As I remember, back in Generation I, Posion was super effective against Bug, wasn't it? They should bring it back, but make stronger Bug Pokémon, I mean with good stats and good movesets.
I found it a shame that they didn't add Bug Bite to Scizor's Gen. IV repertoire. Otherwise...
Scizor: Bug Bite (60 Atk) x Technician (1.5) x STAB (1.5) = 135 Net Base Atk :ksmile:
OR
Scizor: Bug Bite's (60 Atk) effect (2) x STAB (1.5) = 180 Net Base Atk :sweatlol:
Oh, also, since every odd generation, there have been a brand-new joke fish Pokemon and a butterfly-based Pokemon introduced.
Hints:
Odd Generation -- Joke fish -- butterfly-based
I -- Magikarp -- Butterfree
III -- Feebas -- Beautifly
I hope these respective patterns would continue in Gen. V.
