Personality and Characteristics:
Ulrich is the introvert of the group. He doesn't say much about his personal life and is evasive when someone asks him about himself or his family. He seems to have trouble opening up to people and hides his feelings in order to use them all the more explosively in action. Whenever someone is in danger, his feelings tend to surface very quickly. The first example of this is in the episode Killer Music, when Odd is sent to The Hospital and later on slips into a coma and Ulrich blames himself for not being there when Odd had needed him. A similar situation occurs in the second season episode Cold War, when Yumi is trapped under a fallen tree during a blizzard and he cries as he tells her that he needs her while holding her, after several failed attempts to free her, and screams when she appears to have died.

Though on the outside, Ulrich appears to be fairly emotionally strong, he deals with hidden issues in the way that only few could understand. One cause of this are his parents, who are very hard to please and have high expectations of their son. In Zero Gravity Zone, Jeremie berates Ulrich for going to the soccer game instead of helping to fight X.A.N.A., yet Ulrich does not retaliate or change his mind. Odd explains his reasoning after he leaves the room that Ulrich wants to go because he doesn't want to disappoint his parents, especially his perfectionist father who is a businessman. This is later proven in Final Round, when Ulrich's father appears and berates him for his failing performance in school (and even insults his friends, accusing them of being a bad influence on him despite having never met them). A clear example of his bad grades is when he receives a D- on a science test in Nobody in Particular and receives a F+ on a test in another episode (the plus being added "so he can do worse on another") despite having tried his sincere hardest to get a passing grade.

In the second season episode Vertigo, it is discovered that Ulrich has vertigo, which is a chemical disorder that causes dizziness. He shows signs of it when attempting to climb a rock wall, which reveals the condition to his friends. It hasn't seemed to affect him before this point, except in the prequels, when he hesitates to slide down the ropes to the factory floor. Having vertigo does not seem to be a hindrance on Ulrich when on Lyoko, with the notable exception of the episode Bad Connection.

Yumi Ishiyama:
"You're the person who means the most to me."

- Ulrich to Yumi Ulrich is shown to have had an instant romantic attraction to Yumi as seen in the two-part prequel, X.A.N.A. Awakens, eyeing her as she gets a drink from the vending machine and noticeably watching her as she leaves. He can be seen checking her out yet again when he first officially meets her in his martial arts class with Jim, later bonding with her over their interest in Pencak Silat. He has a close platonic relationship with Yumi, based on observation from a distance and repressed admiration, though both he and Yumi constantly waver between just friends and more than that. This admiration can sometimes cause him to do things that might be considered stupid. For example, in the episode, Saint Valentine's Day, he writes a poem for Yumi for Valentine's day, but when he sees Yumi with William Dunbar, who was giving her a bouquet of roses, he reads the poem to Sissi instead, in an attempt to make Yumi jealous. This only backfires when Yumi, becoming jealous, sweetly thanks William for the flowers telling him he "couldn't have made her happier" before topping it off with a kiss. This earned a glare and scowl from Ulrich. He later admits that he actually wrote the poem for her, causing her to smile. He and Yumi finally confront their feelings for each other in Routine, where the two even nearly share their first kiss together (before getting interrupted when a Time Reversion takes place). The two decide to keep it a secret from the rest of the group, however, it seems as though Odd knows about it, considering at the end of the episode he asks Ulrich. "It wasn't all that boring on Lyoko was it, Ulrich?" Ulrich replies by saying, " Your right, Odd. I learned something too, something super important. "

Ulrich has the habit of getting easily jealous whenever he sees Yumi with any 15-18 year old male that is not Odd or Jeremie. When he does see Yumi with another boy he becomes obsessively jealous and starts to question his and Yumi's relationship. Odd even remarks in The Pretender that Ulrich gets jealous when his dog Kiwi looks at Yumi for a moment too long. Ulrich also becomes extremely competitive (as seen in Marabountawhen it comes to winning over Yumi. Ulrich also has the habit to become extremely protective of Yumi when she is in danger usually by cradling and holding her in his arms or by screaming her name when she is unconscious. This can be seen in Cold War when Yumi shoves Ulrich out of the way of a falling tree during a blizzard and takes the impact herself, Ulrich decides to stay with her to keep her from falling asleep and, when unable to get her out and she begins to fall asleep, begins to cry as he says that he needs her. But when Yumi eventually falls asleep, possibly dead, he screams (although Yumi is saved with a Return to the Past). In the episode The Chips Are Down, when it looked as if Yumi might move back to Japan because of business problems, Ulrich actually tries to write a letter to the president in an attempt to at least keep her near the school when finding out her parents would never allow her to become a border. He abandoned this plan once he heard the lotto numbers being announced on the radio. Instead, he copied the winning numbers and activated a return trip, despite knowing by then that return trips make X.A.N.A. stronger, in order to buy a lotto ticket and give it to Yumi's parents, allowing them to win the lottery. This action temporarily cost him his position in the group, and he was banished until they could think of an appropriate response, although he is later let back in.

As of the third season, Yumi talks with Ulrich about their romantic relationship when she says they always go around "in circles" with their relationship saying how "one day they're together, the next day they're not, one day he's jealous and the next she is" and says that they need to cement their romantic relationship once and for all. She then declares they can be just friends, but nothing more on a strictly platonic level. This, in which, clearly horrifies him. However, he begrudgingly goes along with it, though it obviously upsets him. Even after this, however, Ulrich still shows through his actions that he still considers them to be more than just good friends, although he insists they are nothing more than such. In the episode Tidal Wave after saving Yumi's life, he tells her that he would do anything for her. Also in Kadic Bombshell when Odd and the group talk about love after a classroom reading of Romeo and Juliet, Odd teasingly asks Ulrich if he'd be willing to die for Yumi leading Ulrich to accidentally, but firmly, say "Better believe it" before blushing as Yumi came up to join them. Also, in the episode The Pretender, Ulrich tricks a boy named Johnny, who has a crush on Yumi, into embarrassing himself in front of Yumi, because he couldn't stand the idea of anyone else going out with her (although Johnny was far younger than Yumi is, it still upset Ulrich that he liked her at all). However, when Odd playfully teases Ulrich about his relationship with Yumi, he defensively shouts, "Yumi and I are just good friends and nothing more!" and when Odd asks, "Are you sure?", Ulrich admits he actually isn't sure what he and Yumi are. In Echoes, it is hinted that Ulrich and Yumi finally start on their full deep and close romantic relationship after the Supercomputer is shut down.

In "Code Lyoko Evolution," which takes place one year after the fourth season finale, it is shown that Ulrich has fully accepted his strong romantic feelings for Yumi by openly saying to Odd that he loves her and even referring to her as the "love of his life". After some encouragement from Odd, who had been urging him to finally reveal his romantic feelings for her, he struggles to find a way to tell her. He makes two attempts in the episode to tell her how he really feels about her, only to get interrupted each time. The next few episodes hint at their attraction, with Ulrich sometimes getting jealous over William spending time with Yumi (this being seen in Rivalry), getting protective over her (How to Fool X.A.N.A.) and such. In The Warrior Awakens, when Ulrich can be seen dreaming, the ending of the dream before he wakes up are shown to be many thoughts of Yumi.

In Intrusion, which slightly focuses on their relationship, the two get into a fight when Yumi, angry at him for failing to keep a promise to her, writes about him in an essay paper (under another name) in a negative manner about how he is "immature and stubborn" and doesn't care about anyone else. Ulrich is hurt about her harsh words to him and confronts her about it, demanding to know if that is really how she sees him. Despite her claims it was only an essay paper, he ends up leaving on a group mission to be alone and calls for a break in their friendship. Yumi soon becomes guilt ridden after this and decides to apologize to him at Kadic in his dorm, intentionally getting herself devirtualized on an important mission with the group to see him. However, he refuses to open his door to her, but soon ends up chasing after her when she leaves after admitting the boy in her essay was, in fact, about him. In the forest, he still remains hurt about her words to him and Yumi is annoyed that out of all the good things she wrote about him, such as his depth and sensitivity, he can only focus on the negative. She then calls him out for never being there when she needed him and being so touchy and says how she purposely got herself devirtualized in order to see him because she couldn't stop thinking about him. He then admits to her that he should have been there for her for many things and that she is the most important person in his life to him and he doesn't want to lose her, promising to make an effort from now on. Yumi admits the same goes for her about him and the two share a moment, smiling at each other. In Massacre, when Aelita asks Yumi about her relationship with Ulrich, Yumi describes things as "cool". When pressed for details, Yumi admits that things are going much better between her and Ulrich since he has become "more considerate towards her feelings", fights less with William and is much more mature than he's been in the past, leaving her happy.

Odd Della Robbia:
Ulrich's best friend and roommate. At first, as seen in prequel episodes, he and Odd didn't get along well due to their polar opposite personalities. However, as a result of being room mates, they eventually began to mend a friendship after hanging out together for a while. This, in which, only grew in strength and Odd soon becomes Ulrich's best friend.

Being his closest and best friend, Odd seems to know more about Ulrich's private life that any of the other characters, such as his relationship with his parents (as seen in Zero Gravity Zone) and Ulrich even trusts Odd to get Yumi's birthday present for him when he forgot about it and couldn't buy one himself due to having to serve a detention (Lab Rat) although the detention was, in fact, on account of Odd himself. Although the two didn't get off to the best start, as seen in the prequel episodes, Ulrich soon grows fond of Odd, worrying about him when he's hurt in Killer Music and has to be sent to a hospital. He even becomes guilt ridden and blames himself for the whole mess since he failed to be there for Odd when he had needed him the most.

Ulrich has even been been willing to take the blow for Odd, covering for him during a prank as seen in Cold Sweat. This when Odd gives Milly and Tamiya a picture of Yumi in an embarrassing Halloween princess costume from when she was little and Ulrich (reluctantly) agrees to say it was him who posted the picture when Yumi comes to confront Odd about it. Although this action ended up shortly costing him his friendship with Yumi, who felt betrayed, later causing Ulrich to demand Odd to tell her the truth and vowing to do so himself if he didn't (which Odd later does for Ulrich's sake with Yumi). The devotion to his friendship with Odd cannot be said for his relationship with Kiwi however, since he spends more time moaning to Odd about him than not. Odd is always there for Ulrich, offering him advice whenever he needs it. He often teases him about his relationship with Yumi, dubbing them "The Love Birds", often earning a glare from Ulrich much to Odd's amusement. Odd often tries to push the two together, knowing how difficult it is for Ulrich to admit his feelings for Yumi due to his low self esteem and confidence.

Jememie Belpois:
Ulrich and Jeremie have become very good friends throughout the series. Although the two had scarcely spoken before the incident with the supercomputer, they learn to trust each other as the need to defeat X.A.N.A. appears. There are a lot of times where Jeremie gets impatient with Ulrich, especially his tendency to withdraw himself (as seen in Zero Gravity Zone), but he knows to trust him to come through in the end, and visa versa.

Aelita Schaeffer:
Ulrich's relationship with Aelita can be compared to that of siblings where he spends a lot of time protecting her from danger on Lyoko. He even takes to occasionally calling her "Princess". However, they are also good friends.

William Dunbar:
"I don't want see you hanging around Yumi ever again!"

- Ulrich in "Fight to the Finish" Ulrich and William have been rivals since his arrival at Kadic academy on account of his blunt and open feelings for Yumi. Ulrich can be seen instantly disliking William the moment he saw him - literally - during a class project in the season 2 episode New Order where William was Yumi's partner. He spies on the two throughout the project, thinking that William was "completely snowing her". Ulrich had been distrustful and hated William ever since then. However in the episode The Secret after he manages to save the factory from a bomb with William's needed help, the group takes a vote as to whether or not let William join the group, and he votes yes knowing William could be a valuable asset to the team. They still occasionally fight for Yumi's love despite this.

However, in Code Lyoko: Evolution, the two eventually learn to make something of amends in the episode "Rivalry," when William saves Ulrich from falling into the Digital Void. They still occasionally bicker every now and again throughout the series, but have since formed something of a friendship together. It seems that William has now seen that he will never have a chance with Yumi and has given up on her, making his friendship with Ulrich easier.

Martial Arts:
On Earth, Ulrich is a capable martial artist trained in the art of Pencak Silat (a martial art system from Indonesia). At least part of this training is from his PE teacher Jim (presumably a great martial artist himself - although he'd rather not talk about it), as shown in X.A.N.A. Awakens, Canine Conundrum and Revelation. He's also capable with a sword, which is his main weapon in Lyoko. He demonstrates this talent outside of Lyoko in the episode A Bad Turn when protecting Yumi from a materialized Krab using a real katana, and in A Great Day when using a pipe to sword-fight with a possessed Sissi. As evidenced by a quote by Ulrich in Rock Bottom?, he also practices other martial arts, and in Revelation, he copies the famous nose wiping and hopping stance of martial arts movie star Bruce Lee; this occurs during the battle between himself and a polymorphic clone that had transformed into a dark version of Ulrich.

Ulrich has, on several occasions, shown to be the most skilled in Lyoko when fighting. Many times he has defeated multiple monsters with skillful take downs (particularly in the third season), and has outlasted the others, being the last to be devirtualized, such as in the episode Code: Earth. In the second season episode, Revelation, Ulrich is forced to face off against a polymorphic clone of X.A.N.A.'s while in Lyoko. In the beginning, he is shown taunting the clone (which at the time had taken the form of Odd, his best friend) by saying that Odd had never beat him yet. This implies that Ulrich is definitely stronger than Odd. Then the clone transforms into a clone of Ulrich. After a long fight and an impressive display of swordsmanship and martial arts, Ulrich beats the clone, showing once again that he has impressive abilities. Also, in Fight to the Finish he kills the Kolossus, a powerful fire elemental-like creature, created by X.A.N.A. by drawing energy from all the Replikas. (However, its corpse fell on him, devirtualizing him instantly).

Lyoko Avatar:

 * ID Card: Ulrich's ID card shows three round chrysanthemums.
 * Health: 100 Life Points.

Weapons and Powers:

 * Weapon:
 * Katana - Ulrich uses a thin katana/saber as his weapon in Lyoko. Ulrich use it to slice or stab enemies. His katana is capable of absorbing normal laser fire and can deflect it if positioned correctly. He cannot, however, block specialized attacks, such as a Megatank's elliptical laser or a Blok's ice beam. The latter may simply be a matter of timing, as the Bloks tend to catch Ulrich off-guard when using that attack. The Megatank's elliptical laser, on the other hand, has proven to be too much for Ulrich to handle, due to the sheer amount of force behind the attack. Ulrich can only block the attack for a short period of time and the katana is always devirtualized along with Ulrich himself shortly afterward. Ulrich's katana can also be destroyed through a barrage of regular laser-fire (as seen in The Pretender). In Double Take, Ulrich gets 2 katanas, which are simply called Twin Blades. Also Ulrich would seem to be an expert with the sword since he once stated "I could do the same thing when X.A.N.A. attacks in reality."


 * Lyoko Powers:
 * Super-sprint - Ulrich can run extremely fast in Lyoko. Leaving a line of yellow from where he has been, but in Evolution the line's color changes to blue.
 * Triplicate - Ulrich can create two other clones of himself to divert X.A.N.A.'s monsters. But, each clone only has 1 Life Point. The clones appear to be controlled by Ulrich through telepathy. The clones have every ability he does, with the exception of cloning themselves. They can only take one hit before being destroyed, and are automatically destroyed should the real Ulrich be devirtualized. When using this power, Ulrich simply creates the clones as assistants. At first, Ulrich's control of these clones seemed rudimentary at best, since they would often be easily hit. As the series has progressed, his control of them has refined. In the episode Tip-Top Shape, he was able to use his clones to fight three groups of monsters (a Krab, a Blok, and three Kankrelats) without losing a single clone to his opponents. He even toyed with the final Kankrelat, having one of his clones kick it into the air so he could strike it in mid-flight. The clones can also be drawn back into Ulrich in a process called "Fusion".
 * Triangulate - Ulrich and his two clones form a yellow triangle around their target. A silhouette of Ulrich then runs around the perimeter of that triangle, forming a golden barrier. This is meant to confuse the target so Ulrich can destroy it. After the technique is finished, any remaining clones revert to their assistant state.
 * Enhanced Reflexes- A superhuman ability that enables Ulrich to sense whenever lasers are coming near him from behind, and dodge them with ease.
 * Vehicle - Overbike: The overbike is as fast as Ulrich while using Super-sprint. Ulrich also has a Nav Skid that can shoot torpedoes on since season 4.
