Actually, in HG/SS, without Celebi, the leader is Archer. But in all other kanto only games, its Gionnavi. Though Tectnically, Team Rocket is still led by Gionnavi but hes not really commanding them so hmmmmmmmmmmmmmmmmmmmm................im going to say in HG/SS, without The Celebi, the leader is Archer because he makes all their plans. Second in Command of team Rocket in HG/SS would Have to be Petrel, because you see him the most and is sent on the most missions by Archer. Anyway, Hope this Helps!!:)
