WWE and Tekken team up

[Turd Ferguson]

I'd think that Ziggler and Hwoarang would be a perfect match.

This is not an easy thing to do, taking characterization into account, along with fighting style.

HHH was Kazuya (the Devil), now he is Azazel (the gigantic Crystal Insect who destroys everything).

Punk is Ogre (primarily cut-and-pastes other people's moves, is considered a God by some).

Vince is Jinpachi. If only Shane would chain him up underneath Titan Towers. Ironically, Shane SHOULD have been Kazuya, and HHH SHOULD have been Lee Chaolan (and Vince should have been Heihachi, with Vince Sr. as Jinpachi). But it didn't work out that way.

Cena is Paul. Used to try to be a serious threat, now he's just a goof.

Big Show is Kuma.

If we remove the Taekwondo/Kick Exclusive requirement, Miz could be Hwoarang. The guy who just wants the main characters (main eventers) to pay attention to him, but they never do. He even had the hairstyle change due to Military (fictional, even in-universe, in Miz's case) characterization.

Derrick Bateman is Yoshimitsu.

New Japan also teamed up with Tekken and latter with Capcom (also for the SFxT, which they made some SFxTxCHAOS (a faction on the promotion) t-shirts) for some t-shirts and other promotional stuff.
