If you want other SEGA rivalries that personally put SONY Rivalries to shame, here's several more as temporary Ideas:

Ulala (SPACE CHANNEL 5) X Miku Hatsune (Project DIVA) (Sega had something to do with the publishing I believe. Correct me IF I'm wrong.)

Metal Sonic (Sonic CD) X Shadow (THIS IS THE ONLY ACCEPTION TO MY RULE.)

Akira (Virtua Fighter) X Grace (Fighting Vipers)

Gunstar Hero (Either Red or Blue) X Epsilon Eagle (Alien Soldier)

Tyris Flare (Golden Axe) X Centurion (ALTERED BEAST.)

Espio the Chameleon (Sonic) X Joe Musashi (Shinobi)

Ryo Hazuki (Shenmue) X Kiryu Kazuma (Shenmue)

Alex Kidd X Sonic

There are too many to list for rivalries... Some of them are obscure even! But being someone with a Knoxload of Ideas, this should be a start...

I'll mention their rivalry connections later, unless you oppose of this Idea (I tried to find an opponent for Axel of Streets of Rage, but found nothing...)...
