it evolves from shelmet
You get an Accelgor when you trade Karrablast for Shelmet. After both arrive, they will evolve, into Accelgor and Escavalier.
You have to trade if for a karrablast
Accelgor does not evolve into anything.
Shelmet do not evolve by level in Pokemon White. Shelmet evolve into accelgor when traded for karrablast if neither the shelmet nor the karrablast is holding an everstone.
Shelmet evolves only when traded for a Karrablast. Both will evolve, into Accelgor and Escavalier respectively.
You have to trade a pokemon to get accelgor. I can't remember the pokemon, though.
Accelgor is based on either a Ninja, an Auto Racer, a Bagworm Pupae, or a Giant Tune Worm, as it states on Bulbapedia.
If you want a fast pokemon get accelgor and if you want defense and physical get Escavalier. But I rather get Accelgor becuase its fast and has decent special attack. BTW Accelgor has bad defense and Escavalier has slow speed
Accelgor is #617 in the national pokedex, and it is a Bug type Pokemon.
Volcarona,accelgor
Stunfisk.
Accelgor, Bouffalant, Escavalier, Druddigon, Vanilluxe and Volcarona and that applies for both Pokemon Black and White.
