if Silver is Nishi then Green = Izumi Shirona = Reika Garchomp = Muscled Warrior (or something like that) Lance = That guy who fuck the false Reika and then die Snorlax = a nice fat guy who thumbs you up
Lance and Dragonite might be Sakata and Sakurai since it seems a bit weird to leave them out of a parody group shot, but... it's definitely a curious choice, if that's actually the case. The only other thing I could pin him as would be Daimon or Inaba (like Maguitus suggested) though Inaba seems like a discredit to Lance's badassery.
If we go with the idea that Garchomp is Daimon, would that make Totodile Takeshi? That's kind of adorable in a really goofy way. Snorlax might be Hoi Hoi (the panda) by similar logic. LAYS AROUND TOO MUCH. 0 POINTS.
