“Hi! I’m Omochao! I’m here to help you.”
Omochao is a robotic Chao best known for his appearance in Sonic Adventure 2 and Sonic Adventure 2 Battle. He will act as your guide throughout these games and can be found at various locations throughout most levels. You can even grab him and throw him at enemies, although he won’t be too happy about this.
From the main menu of these games, you can access a tutorial in which Omochao shows you the basics of Sonic Adventure 2, Chao, and much more. You can also compete against him in one of the races!
So how do you get your very own Omochao in your Chao Garden? Unfortunately, you cannot through normal means (or is that a good thing?). The only way to obtain an Omochao in your garden is by using a cheat device or something similar. See the hacking articles in the Chao Island Guides section for more information.
Sonic Adventure / DX (Dreamcast, GameCube, PC, PS3, Xbox 360) — You can see Omochao in the race entry stadium in the Station Square garden. You can also see Omochao position in the races to direct the Chao the right direction.
Sonic Adventure 2 / Battle (Dreamcast, GameCube) — The players main guide through the game, and appears in the levels giving hints, in tutorials, and also in Chao races.
Phantasy Star Online (Dreamcast, GameCube, Xbox, PC) — You could obtain and equip robotic items called Mags to give your character stat boosts. One such Mag was a Chao, and another was a Robochao (which was actually Omochao).
