All for one, and one for all, but one is better than all y'all.

Loki was the heavy in The Avengers (2012), so it's only fair that he's the supervillain equivalent of Diet Dr Pepper Cherry. But just because Hawkeye and Black Widow lack superpowers doesn't mean they're Diet Dr Peppers. I think they should be reassigned as Dr Pepper Cherrys, leaving Nick Fury, the head of S.H.I.E.L.D., as the sole Diet Dr Pepper.

The only opinion that matters, however, is Robert Downey Jr.'s.

Correction: Robert Downey Jr.'s agent, because that's who negotiated for Downey's name, and Downey's name only, to be placed above the title in the contractual credits on the ensemble film's one-sheet.

That guy or gal is the real superhero.
