What you are seeing rn is what I call "Phase 1", CR X is gonna get 2 forms in game to back up his huge nerf from the og (CR X's base form is like a slightly weaker super sonic)

Phase 1 here is like a buffed super sonic, I won't reveal his abilities yet but these forms get alot of downsides for CR X

During the 1 minute transformation sequence, CR X's body grows to be like modern sonic. He forces years of growing of sonic's body to a single minute which causes intense bleeding due to how quick this became and ofc intense pain. Take it as a false super sonic that's even stronger than the usual super sonic. An orangish red in black aura surrounds him along with smoke that he can change the structure of and also what matter it is (liquid, solid and gas) and reform it however he wants. Yes, you will fight this. Good luck when the time comes
