Nirvena is a 38 year old nidoking living in the sonic world, residing somewhere near Pinball Highway. He's fat, his weight being comparable to some heavier known pokemon as well as some of eggman's mechs/robots. He absolutely enjoys going on fun runs on pinball highway, this is where he has practiced with sonic speed. He has the powers of a nidoking and, as just mentioned, sonic speed. Admittedly, he's always been chubby. While not at the size anymore, his nickname comes from being the record holder for fattest nidoking (at one point), getting the title of "Plumpking". He's making some strides in slimming down though he has caved in to cravings every so often.
