We have such a great cast of characters so far!

Regarding speedsters, I'm pretty familiar with playing the mutant, X-Men variety. Think of the speed this way - what can his body handle? Unless he's got an even [i]more[/i] increased durability and homeostasis necessary as part of his already super speed (and by extension, homeostasis), going 480 MPH is going to [i]wreck[/i] him. Right now, you have him traveling just under the speed of a Boeing 747 when it's cruising. They travel at 550 to 600 MPH. While I find the bionic boots to be an intriguing idea, I don't think they're realistic in what his body can handle. Even with his demon endurance, I don't think his body would be able to function under that speed. If you want to keep the bionic boots, maybe consider lowering it to double, rather than quadruple.

That's just my input, but it's ultimately up to Saarebas.
