Sorry, but I'm going have to say no to that power. Diseases can be played in such a way that it can work in the RP, but Mikael's power can't be. It's simply too strong, all he has to do is release his virus and everyone's screwed. Only two characters (Newt and Henry) could hope to stand a chance against him.

Plus, NEST wouldn't let a Meta-human like him out into the public. So, yeah.
