This is what happens when you let Square-Enix redesign your comic-book characters – they do waaaay more than add piping and collars. In Darkseid’s case, it looks like they amputated both arms below the bicep and replaced his forearms with leftover Gundam bits.
Either that or Darkseid is attending an intergalactic comic-con and trying to cosplay as a Super Saiyan who forgot the spiky blond wig. I’m usually all for Play Arts Kai screwing around with designs, but I really think they went a little too busy on this one. It’s like a fashion Apokolips.
