i'm just glad there's plenty of actual good bug-type pokemon nowGen 1 wasn’t meant to be whatever pokemon is today IIRC. It’s meant to be more of a traditional JRPG so they intended all the poison types to poison you in dungeons. It’s also why so many late game Pokemon are direct upgrades over early game ones. You’re supposed to box them and use the new ones like selling off your iron sword to buy the Immortal Phoenix Blade of Eternal Ruination.
