We all know the sonic and super sonic chao right?? do you want a hyper sonic chao???? if so, then follow these steps
Step 1: Buy And Hatch A Shiny White Chao Because hyper sonic is white and he also flashes the rainbow but white is the main color of hyper sonic
Step 2: Make it a Neutral chao and raise it to be a running type Because that's how you make sonic and super sonic chao
Step 3: Wait till the chao is in the blue cocoon because that's means the chao is becoming a adult and is entering the first evolution
Step 4: After it evolved into the right type and alignment, give it red drives or animals of the red group then wait for it to enter it's full second evolution
Optional: If you want it look more like hyper sonic later give it purple drives to make the spines go straight up more
If you accidentally make it the wrong type or alignment: If that happens try it again with a new shiny white and repeat the steps or wait till it reincarnates so don't abuse it or if it's dark run you can make a hyper shadow chao (Hyper shadow is a custom hyper form for shadow) by repeating the steps of this guide but don't do the optional part plus after it evolves into the basic hyper shadow chao give it more running drives instead of power drives.
Trivia: Hyper Sonic only appeared in sonic 3 and knuckles
He is the strongest form of sonic (Most Likely)
Even if Hyper Sonic flashes the color of the rainbow in sonic 3 and knuckles you can't make chao do flash the color of the rainbow so you have to get a shiny white for a hyper sonic chao
