While it's true he's artificially "enhanced" like Cap, unlike Cap, Mace's abilities are non-permanent.
Yeah, but so are a lot of superpowers. Hourman was called that because he got his powers from pills whose effects only lasted an hour. Green Lantern rings run out of juice after 24 hours of use (or originally, after 24 hours no matter what). Bane can temporarily enhance his strength with the Venom super-steroid. Japan's Ultraman can only maintain his giant form for 3 minutes. The title hero of Ben 10 could originally change into a given alien for a maximum of 10 minutes at a time. Three different comedy superheroes from '60s TV -- Underdog, Captain Nice, and Mr. Terrific -- all got their powers from special pills or serums whose effects wore off after a while. All these characters are recognized as superpowered heroes or villains. It's unprecedented to disqualify something from being considered a superpower just because it's temporary.
So yeah, they're "real" but not intrinsic to who he is. It's an important distinction because it's like me saying I have the "power" to be immune to pain just because I shot myself up with morphine (though if I did, I probably wouldn't be coherent enough to make that claim, but you get the idea.) It's also especially important coming after claiming to be an Inhuman because it's 100% voluntary, while the Inhumans mostly have their condition inflicted upon them. He can walk away at any time and be "normal". They don't have that luxury and however well meaning, that makes him a fraud.
It is obviously valid to say he is not an Inhuman. It is obviously valid to say he is a fraud because of that. But it is bizarre and without precedent to claim that a temporary, drug-induced superhuman ability cannot even be called a "power." Maybe I care more about the exact wording than the rest of you because I'm a writer, but to me, it matters.
Side note: was that crazy exploding bullet meant to be the same type that wounded Luke Cage? Seems like it was. If so it pretty much confirms what most suspected in that it's leftover Hydra tech.
Oh, I didn't think of that. I hope that was intentional.
I don't recall them saying that, Phil said he wasn't a inhuman and he would be correct.
That was later. When he first realized that Mace took a serum, he said "You don't even have powers."
That serum is dam dangerous for sure, an army of amped up soldiers will never end well. Remember in First Avenger when the Doc was looking for more than a tough guy to be Captain America.
I think Mace has shown that he can at least somewhat be trusted with the power. He's not the most honest guy around, but he's not a bully. He took advantage when people shoved fame and glory onto him, but he did resist doing so at first, and he has an awareness that it's more than he deserves. Someone with humility and self-doubt can be trusted more with power than, say, an arrogant SOB like Talbot.
