^ In some ways I think that that is what she's being made out to be. They are definitely pushing this aspect of her character with everything that Hunter said. Not only is she effectively a person with photographic memory, they are making her into someone who can do anything really easy because of her "powers". Not sure I'm liking this or where I expect they'll go with it.
If they limited it to just fighting then it wouldn't be as bad, but obviously they aren't. Too many comments were made about this "mocking" ability of hers, even though it's not yet been defined as an ability.
Personally I would rather she not have any "powers", just like in the comics, but she needs to be (for whatever reason they define) able to beat characters like May in hand to hand combat. Mockingbird needs to be of Avengers quality, while May would miss the cut.
In my opinion her "mocking" ability has not come off as a power at all, it's just implied that she's one of those lucky individuals who is able to pick up languages/skills relatively easily. I mean, as far as I remember she has yet to watch someone doing and immediately be able to copy their whole style in the same way Taskmaster is able to: she's just quick on her feet, naturally skilled, and a fast learned.
Just to check against the general audience I went ahead and quizzed my mom, who is perfect for these kind of things since she's seen (most) of the MCU films and regularly watches AoS but has never picked up a comic book in her life and has no outside knowledge. So I asked:
Q: Do you know who Mockingbird is?
A: Who?
Q: Bobbi Morse? From Agents Of SHIELD?
A: Oh, the blonde girl who fights with May! Yes! I love her!
Q: Awesome. Does she have a power?
A: No, or at least not that we
know of. Right now she's just like Black Widow, she's a really amazing fighter. I love that about her.
Q: What about... Do you remember when Lance - her exhusband - said that she picks things up really quickly?
A: Yes.
Q: Do you think that was meant to imply that she has the superpower immediately pick up skills or did they just mean that she learns things really quickly?
A: The latter.... She just picks up things and can copy people after watching her, right? *Uncertain* Why is it suppose to be her superpower?
Q: No, no, you're exactly right. Final question: three way fight between May, Mockingbird, and Black Widow. Who comes in first, second, and third?
A: *No Hesitation* May, Black Widow, Mockingbird.
Q: *To clarify because maybe she reversed it?* May first, Black Widow second and Mockingbird third?
A: Well, Mockingbird has those sticks but... No, I'm sticking to my answer.
Q: Wow, so you have May coming in first.
A: Oh, no question.
Q: I mean you'd but her above Black Widow? Mind if I ask why?
A: *A bit insulted I would even ask* Well first off have you ever seen May lose a fight? I mean, do you remember the last episode? That one guy with all those cool new weapons and the knifes and she took him down easy. No, May is definitely on top.
Q: Really... Where you would rank the other non-superpowered fighters?
A: *Thinks for a while* Well it's hard for me to think of all of them.
Q: Well, Hawkeye, Skye, Coulson, Ward...
A: Peggy.
Q: Yeah. Well all of them.
A: Hmm, well Hawkeye is above Skye, and she's at the bottom I would say, definitely. Then Coulson - physically he's got nothing, but he's smart, you know? Then Ward... Ward is good but he's
nowhere near those women, you know? And Peggy.... It's hard to say since I haven't seen as much of her but from the short, I suspect Peggy is just above Ward. But none of them can touch those top three.
Q: May, Widow, and Mockingbird?
A: Exactly, those three are.... I mean Hawkeye, he is the other nonsuper powered Avenger, right? Well he is excellent at what he does don't get me wrong, he is amazingly skilled but it's a limited skill set. May, Black Widow, and Mockingbird? Those three are heads and tails above the rest of who you mentioned.
So in review, here is what my mom figured out just from the show: She didn't recognize her code name, but she knows Bobbi, knows she isn't superpowered but can learn skills easily, and that she specializes in using her batons. She knows that she is one of the top non-powered fighters in the MCU but for what I am going to say are fangirl reasons, my mom simply thinks May is the best thing ever. However, she gets that Mockingbird and Black Widow are about on level (and rates Hawkeye almost hilariously low especially considering she actually likes him quite a bit!)
