In the spin-off game Pokémon Ultra Fire Red XD, Deisnutz has an alternate form called Deisnutz XD. It is a Ghost/Fighting type with either Cacophony or Levitate as an ability. The main design difference is that the XD Form has bright blue hair instead of golden yellow. The shiny form's coloration becomes reminiscent of Oni from Street Fighter IV. Its canonicity is debatable however, as the events of the game take place inside of Kanye's mind.
The design of Deisnutz and its pre-evolution, is based off the infamous "Deez Nutz" meme. The design also draws inspiration from Dan Halen from the show Squidbillies.
Deisnutz looks like Nutjobber, but now with hair reminiscent of those acquired by Super Saiyans from the anime Dragon Ball: Z. It's shiny coloration is based off of Akuma from Street Fighter.
Its name is a combination of the words "Deis" and "Nutz".
Shinattsu is a combination of the words "true" (shin) and "nuts".
Deisnutz was originally going to be Mega Nutjobber before its official inclusion in the game.
