Archetype:Earth is basically the mentioned LONG ago Arcueid Brunestud at 100% power (Is opposed to 70%.), and is a princess. Her Last Arc finisher traps the opponent in an force field (A common occurrence for most pre-Fate characters.), traps them further into an orb of pure light, the light explodes, decreasing all health to 0%, thus complying to the Unconscious rule as to how to kill an opponent. No longer is the Marble Phantasm as powerful, as Archetype:Earth has full power, and more authority over the Earth. In Melty Blood, it was even mentioned by Ciel that there is a possibility of her changing things like the ice on the North/South Poles, changing of Axis, etc.

Evidence: Unlike Arcueid, Archetype：Earth has full access to Arcueid's full power and more authority over the planet than she normally possesses. She is called an Ultimate One in this state, taking on her original appearance before losing her hair to Altrouge Brunestud, and the part of her in control is the subconscious Crimson Moon side of her. Normally limited to the Millennium Castle in their "dreams", this form is her awakening to experience the human world for the first time in Melty Blood Actress Again Current Code. Ciel believes that Arcueid managed to awaken her Origin, but Archetype denies this, declaring that they are intrinsically a single being. She simply has a very long waking period, as the basis of life for her is far too vast compared to the living organisms that live on the surface.

Shiki Ryougi recognizes a overwhelming aura flowing from her during their conversation, stating that she cannot see her death, going as far to say that she does not have a death, and that she is a monster. She is able to directly affect the entire planet. Ciel mentions the possibility of her melting the ice of the North and South poles, or even disrupting the axis of the earth.

Man... And Magical Amber is meant to be the most powerful character in the Nasuverse...  NASU-SAN! DEFINE YOUR EVIDENCE!!!
