Suggested by Sonic Mystique is a shapeshifter but that won’t help her a ton in this round. What she really needs to focus on is her high tech weaponry and second level mutation. With that she has the strength to easily crush the Brood or could blast him from afar. Either way I don’t see the Brood being able to win here. They are powerful in a group but if it’s just 1 then there is no threat. Mystique wins.
