I’ll be honest, I don’t know a lot about the crow, I’ve seen a few of the movies but not the show and I know nothing of the comics.  I do plan to re-watch at least the first movie before this starts.<br/><br/>That said, hear is my idea.  It requires a bad guy scientist, a counterpart to beast (not sure if any of the listed villains fit that).<br/><br/>Sara has a mutation that doesn’t affect her directly but insures any kids she had with just about anyone would be alpha level mutants (not sure that’s the right term, I mean they would be on or above the level of magneto and Xavier).  The x-men learn of her because Xavier gets a strange reading, something between human and mutant.<br/><br/>Chris (my OC cloud shark) had been with the brotherhood briefly (during which he became friends with Sabertooth) before going to the institute.  He had gone there in hopes of regaining his memory and hadn’t intended to spy but when he learns about Sara he contacts Sabertooth and sends him the data.  This counterpart of beast’s thinks if they get there hands on Sara they might be able to make a formula that would activate dormant X-genes and enhance existing mutant powers.
