Tougher than Knuckles.With all the Cross Tag Battle news going around, I was reminded of a certain gif I saw on Tumblr. There's this character in Under Night In Birth named Merkava, and... well... it has really long wavy arms. After I saw the new Nuckelavee shirt design RT released, I decided to go ahead and make an animation featuring another wacky inflatable arm tube man. I made Knuckles himself, but the arms are 100% just ripped from Merkava's sprites; they're REALLY good looking you guys.Here's a look at the gif this is based on.Commissions:
