Accelgor is #617 in the national pokedex, and it is a Bug type Pokemon.
You have to trade a pokemon to get accelgor. I can't remember the pokemon, though.
You get an Accelgor when you trade Karrablast for Shelmet. After both arrive, they will evolve, into Accelgor and Escavalier.
Unown is the Pokemon that comes after Snorlax in the Sinnoh Pokedex.
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
