Some stuff about him.

• Sonic12 can sometimes make the game, SONIC12, play like a regular, poorly-made Sonic fan-game with no disturbance whatsoever.

• He can regenerate any damaged tissue if possible. He doesn't do that most the time since he likes pain.

• Sonic12 can get too excited torturıng the others, as he would let them live in a excruciating pain close to death.

• Sonic12 is capable to contort the person's own perspective of reality as a way to freak them out.

  • He can also do this in his game as well.

• Sonic12 could transform into his Super Sonic form. But since the Chaos Emeralds don't have that functionality in Sonic 1, it's unlikely.
