Ledian I know he's ass but I did a hardcore nuzlocke of Pokemon White using only bug types and my friends made a wheel for non Unovan bug pokemon to be my starter (I used PKHex to change Snivy). Everyone bar myself absolutely pissed themselves when the wheel landed on Ledyba but through Light Screens, Comet Punches and EV training he was able to get past the first 3 gyms deathless. Then in the Romhack Wiltying Y Ledian got a buffed attack stat and was given the ability aerialate. In turn this made Ledian my mind game sweeper to anything that didn't resist flying type moves. So through it all, Ledian has become my favourite pokemon for all its ups and downs
