Really first one to come to mind is CM Punk. Very popular wrestler, who’s already set up to be in Cobra with his Cobra shoulder tattoo and Arashikage forearm tattoo. John Cena’s also always been vaguely military themed, but he’s crossing into movie star status and might be harder to sign for a one-off GI Joe deal.
Regardless of what I'll say below; even entertaining this idea makes these two probably a hard no. CM Punk is not only currently getting action figures from Mattel, but also works for WWE that jealously guard things like merchandising of their 'brands.' Which, for them, means people. There's basically no way I see Punk getting an action figure outside of the Mattel WWE line until he retires and gets a Legends contract. And I don't see Hasbro wanting to do it because of the Mattel connection.
Cena has the same 'works for WWE' problem for the moment - but maybe not too much longer. The other potential problem is that he's got an ongoing DC show and the DC licensing is going to, you guessed it, Mattel. So again, Hasbro would be in a position of putting a guy Mattel has double-rights to make action figures of into their own action figure line.
Now, if you've ever wanted to see Seth Rollins as a Ninja Turtle, I've got fuckin' news for you.....
There’s a choice that’s bound to be a little polarizing, but what about current athletes?
Absolutely not. The last thing I want is any more 'celebrity cameos' in G.I. Joe. We're very lucky that Sgt. Slaughter never really became super problematic. Can you imagine if instead of Slaughter the big name for Joe had been Hogan? My god, ew. Especially now when so many different celebrities are so divisive in one direction or another, it's a recipe for disaster, in my book. Or at least even more endless online arguing.
If anything, I'd love to see popular -characters- become Joes. Imagine if Hasbro convinced the Big Movie Business Guys to let them Joe-ify John Wick or Rambo? Yes, played by real celebrities, but with that level of separation that they're engaging with the character, not the actor. Or actual Classified versions of the original Predator team?
