About "Nancy".
Comes out on bonus stage.
Whether you win or lose (haven't seen anybody beat it)
goes on to next stage.

Doesn't block any moves.
But has huge lifebar (like maybe 10times normal?)
Can't juggle, attacks even when he's getting hit.

Missiles, Lasers, etc.
Maybe after you beat him you might get a bonus item??
Nobody has beaten him yet.
