*Post gen 2, with exceptions like Tyrantrum (honestly, who doesn't like T-Rex Pokemon?)
A good deal of Gen 2's dex was originally meant for RBGY, but there was apparently not enough space, that and GSC is considered a sequel to the 1st gen games complete with Kanto postgame and a Red superboss.
That said, this Pokemon in particular would definitely
grind a few gears.
