Athos' ability does not work that way. He gets magic before ability transformations, not things like Cielo which is in-battle. I confirmed this with the admins, Athos can take Cielo's magic no problem, and his transformation too but it's up to interpretation.
Roo can easily kill Fortune. Hell, GENE could do it as a bunny with one of his shockwave moves.
