This article pertains to the beta elements from Sonic Adventure.


Sonic Adventure was originally titled Sonic RPG, to be released on the Sega Saturn. However, by the time the Dreamcast came out, the developers realized they would need a better system that could handle the creature Chaos.

Classic Characters

Sega originally wanted the Classic forms of the characters in the game, but decided to fully use the Dreamcast's capabilities, and ultimately re-designed Sonic, Tails, Knuckles, Amy, and Eggman.

Super Sonic

Skip to 0:47 to hear the voice clip.

 Like in previous games,

Super Sonic was originally going to be playable in regular stages. It is possible this was removed for more bug fixes, as the game was a little bit rushed at the end of development. There is an unused audio file within the game's data in which Tikal explains how to transform into Super Sonic.

Unused Sky Chase Dragon

There was an unused mini-boss of a mechanical twin-headed dragon that was going to be a mini-boss in Sky Chase Zone. It is invisible, but it follows the Tornado in flight without damaging it.

Station Square

Origonally,  each area of Station Square was going to be completely connected. Also, more pedestrians where going to roam around the city.

Timed Train

The train was possibly going to leave and arrive without the player's boarding, but this was possibly removed because the areas would overlap.

Unused Duck enemy 

In the Sonic Adventure Autodemo , An unused duck enemy was found in Final Egg.
