Aliasing hank_mccoy → beast_(marvel)
Link to alias

Reason:

Same character, both tags showing the same X-Men character (with one or two* images of someone cosplaying as the X-Men character). Beast is his main hero name, with Wikipedia has his alter ego name as Henry Philip "Hank" McCoy.

EDIT: The tag alias hank_mccoy -> beast_(marvel) (forum #253934) has been rejected by @NotMeNotYou.
