>>28371280I guess, gen 2 introduced dark and steel, added quite a few ice types off the top of my head
gen 3 went a bit crazy on the dark types I think 2 grass/dark, 2 water/dark, 1 dark availalable very early that is common (barring zigzagoon).
Also grass got good treatment with Breloom, Cacturne, Shiftry, Tropius, Cradily.
Gen 4, idk. seemed to patch up mechanics and pokemon so it's all over the place (evolutions, physical/special split.
