You’re project Shadow, you’re the hedgehog who is all of himself, the biggest rival to Sonic the Hedgehog, and you work for G.U.N. It’s been 7 years, the rivalry between you and Sonic continues, the Restoration HQ is on guard, and Eggman is retired. Tangle and Whisper invited you and Sonic to their place to show you something they learned. Tangle cracked her knuckles before getting Whisper into position and doing a Steven Universe-esque fusion dance, but, without the zest. Tangle and Whisper than fused into something they called Tangsper, but then Sonic had said-

“Amateurs.” Sonic crosses his arms with a smug look, which made Tangsper turn to Sonic in complete offense, daring him to do any better. Sonic gives you a signal, and you reluctantly get into position

“Fu…sion! HA!!” You and Sonic both say in unison as you both perform the fusion dance, as you and Sonic then fuse into one being, and come out as a more dragon ball-esque fusion, with the vest, wristbands, belt, and baggy pants

“Oh that’s BULLCRAP!!” Tangsper points her finger at your chest, she didn’t believe the fusion dance was better than their own fusion dance
