Accelgor (Japanese: アギルダー Agilder) is a Bug-type Pokémon. It evolves from Shelmet when traded for a Karrablast, which evolves into Escavalier simultaneously. Neither evolves if at least one holds an Everstone during the trade.
Accelgor has a large pink head reminiscent of a helmet, adorned with green stripes, a black star-like marking or hole on the front, and a swirled shape in the back, with its eyes in a shadowed crevice giving the appearance of an annoyed pout. The rest of its body consists of blue, segmented cloth-like tufts, with ribbon-like extensions at the top of its back. Its arms appeared to be crossed, as if in an aggressive mood.
