If Ralf gets the charge motion back for his Ralf Kick you can kiss the Yagami team goodbye. Nuff said right there.
Even if he doesn't, having TWO Ikari members with the Moon Slasher pretty much wipes them out.
I mean, if Ralf is brought back to his old strength, he's possibly one of the best all-out-offense characters in the game. Clark is more than a match for any other grappler in there (except maybe Goro), Leona is one of the best aerial/tactical characters in any game, and Heidern would redefine defensive play.
All in all, if that's what Eolith did, they'll be one hell of a team.
But hey, I'm biased. The Ikaris are my favorite team by far.
