What does it do? I don't have the Legion PAC and this is a new one to me.

It's the same as KC.

Can Wild Card's use it?

Yes, just like the KC ability, and again the stuff based on "symbol" will not work for WCs, as they don't have the symbol.

What Harpua said. They wanted to have the same ability that KC figures had without breaking the seal of letting in characters that never appeared in KC, which was a wise choice.
