I’m not a great expert about the marvel comics and I got a new target boost that says extra damage to the brotherhood. So my question is, what is the brotherhood and who is in it? I’m suspecting the hood but I don’t own him myself and is only the name so far 
some marvel universe experts here?
Off the top of my head, Magneto may be the only Brotherhood member in the game at present - please correct me if I am wrong here. The Brotherhood of Mutants basically think they are superior to the ordinary human race, they are portrayed in the X-Men films (as well as the comic books, of course).
And I should qualify the above, I am no Marvel Universe expert! Just knew that from watching the films.
The current members of brotherhood are magneto(classic) (first incarnation), juggernaut (Eleventh Incarnation) & Daken (fourteen incarnation). Magneto (marvel now!) He is part of cyclops’s uncanny xmen. So I believe there is no effect. Daken was in brotherhood after he was mystery alive and re appear fighting against xforce to awaken En Sabah Nur(kid apocalypse) into turning Apocalypse.:
Thanks for the clarification
You are welcome, im very much a fan boy.
WTF? I just realized Juggernaut is not affected by Brotherhood attack. 
((((
For some reason juggernaut is affected by xmen boost, magneto is the only one affected by the brotherhod boost, prety pointless if you ask me.
I’m by no means an expert on comic book history but was he ever part of any of the brotherhoods?
Edit: He has been an x-man in recent memory so probably at other times too.
