I can't. Thus the purpose of this thread is to make you do it.

Obvious icons of past platforms include Mario or Link for Nintendo and Sonic for Sega. And maybe also Raiden. Perhaps less obvious would be Pacman or Clyde for Atari.

Possibly, Capcom icons like Megaman or Ken/Ryu or M. Bison can qualify as NES icons.

We've got Master Chief for XBOX and I don't much else about that console. Maybe GLaDOS for 360.

I don't want to mention PS1 'cause I'll just start listing FF7 characters... and Squall. PS2 would probably be Sora and Riku or Dante from DMC.

Anyway, let's put our heads together and find these iconic icons.
