idk if I'd really want him to be, but they could try to go after Hayate if they wanted? Try because he has a level 80-something Gardevoir that he always keeps on him, so anything done to him mentally would kind of... be wiped clean once she was released and saw him acting unusual. Though who knows if Hayate has won over Archer enough to avoid him wanting to target him

and I pitched a plot idea last month involving a bunch of Psychic type antics including possible mind control, so depending on what the mods do with / think of that they might get a chance to do something like that in a grander scale someday?!
