S.O.S S.O.S!

I'm in a fanfic emergency!

The problem is, so I'm writing a fanfic about Tony Stark's daughter (not published yet) and she's going to go to the x men school. I'm making fandom crossovers and have already figured out some of their powers.

First for Sherlock:
Sherlock: deduction (I'm making it a mutant power in this cause I couldn't think of anything else)
Mycroft: same as above
John: ? (help me)
Moriarty: maybe invisibility so he can rob people but if you've got a better idea... Shoot!
I have the most characters from Sherlock because it's part of the storyline. The other fandoms going in will probably have fewer characters
If you've got any other suggestions for other Sherlock characters comment below

Divergent:
Tris: fearlessness (obviously)
Peter: computer genius
I only don't have Tobias because I can't think of a power for him. Any suggestions!

THG:
Katniss: archery (bet ya didn't see that coming)
Suggestions?

Doctor Who:
Here is my problem:
I CANT DECIDE WHETHER IT WILL BE TEN OR ELEVEN DX!!
My sister, the non- whovian told me:
Her: well why don't you just put them both in?
Me: you are such an Anderson... Oh wait. Oh it's Christmas!
Her: who's Anderson? And it's June by the way.
Me: oh sister dearest, you see but you do not observe.
Her: what the heck!
Long story short, I got the best idea.
Because I can't decide, I'll simply...
*dramatic pause*
Make them twins!
I know I know it's a stupidly stupid idea but I just couldn't decide! Plus it's double the doctor and who doesn't want that!

Anyway what could their power be?( I say power because if they're twins then I think that it would be cute if they shared the same power) and don't say time travel because then the TARDIS wouldn't be needed.

Anyway that's all for now lovelies!

(Ps yes I do make Sherlock references when stressed)
