User blog comment:Desert Croc/Season 3 Roster + Season 4 Hints/@comment-25656629-20151125025825

Let's see..

Season 3:

The Fury VS The Pyro?

Samus Aran VS Ellen Ripley?

Blaze VS Krystal?

Pit VS Ness?

'Tis all I got for Season 3 at the moment, but for Season 4, here's one additional guess:

Killua VS Trunks? It's a stretch, but worth a shot
