>>51342656He has potential to be set as secret, charming, villain (though it'll be otome shoujo genre charming). President of a mega-corporation with vast wealth and influence, that dabble in darker shits. Sadly, not gonna happen since he there is no intention from GF to set him as one (even with a story where he fells to "power corrupts"). Besides, chairman of big corp as villain trope is overused.
Best bet is for another Legends game set in Hoenn; Steven's ancestors is pretty much guaranteed a villain
and a female, just like Cynthia has Volo
