Don't worry, most people are cannon blind to Gen III at the least because it got kind of overshadowed by the others.

Archie is the leader of Team Aqua so he's kind of a villain, but really he's just an extremist with good intentions shame he's kind of nutso about it though. But he's actually pretty friendly and seems sorta mellowed out since he's a water obsessed person in a water world right now XD;;;
