The Avengers: Age of Ultron ****Now with Spoilers in living Technicolor***

Spoilerish..

If Klaw, wouldn't he be the enemy of Black Panther? Teams up with Ultron in the comics too.

EDIT: nevermind, misread what you said. Yes, if Klaw is involved, there has to be a lead in to Black Panther.

It fits with rumors that they're subbing vibranium in for Ultron's traditional Adamantium body from the comics.
