Ryu and Ken Masters vs Billy and Jimmy Lee

Sou-Setsu-Ken vs Ansatsuken.

Feeling that the Ansatsuken duo of Ryu and Ken Masters have stolen the spotlight from them, the Lee brothers issue a challenge to Ryu and Ken.

Not one to back down, Ken and Ryu (who was training in the volcanic regions of Hawaii at the time), accept the challenge.

Ryu and Ken: Third Strike versions

Billy and Jimmy: Rage of the Dragons versions

I love Double Dragon, but I don't see them winning against the current incarnations of Ryu and Ken.

Ditto

This may sound harsh but Billy and Jimmy don't stand a chance.

Ryu and ken all the way.Unless DD gets a new game soon and they become quiet a bit more powerful.

Depends, Alpha versions of Ryu & Ken lose, But their current incarnations can take it.

I'd be really surprised if they even beat the Alpha versions

I think they can, Alpha versions are weak.

I don't remember the DD doing anything canonically other than physical non-extraordinary MA techniques. Hell, someone like Adon would give them trouble.
