Dont move on Stage

[Silverthorn]

In LF2 everything can move

Back to the problem...
Why do you want to make a character with those properties, you can't even exclude him from the character selection menu. You say, he is only for stage, I say, if he's a character, you can also use him in vs, 1on1, 2on2, and battle. I think, it'd be better just to take a type-3-object, and make it do random attacks.
