Well, I haven't really thought through it, but I'll give you some examples I suppose....

Mario & Link, as I said I liked that.

Bowser & Ganondorf, Two main villains

Peach & Zelda, Two princesses go head-to-head

R.O.B VS. Game & Watch, I like this one too

Captain Falcon VS. Samus, Two bounty hunters so why not?

I'll think of some more later.
