[@knighthawk] Okay this one is a bit tricky for me because speedsters, which Tohi seems to be to me, have never really been my strong suit, I basically pay no attention to them so their limits are a bit of a blank to me. Tohi obviously is fast, but busting out 480 MPH with his tech legs and knocking people around with about 3000 hits per minute seems [I]really[/I] fast. Again my knowledge on speedsters is pretty sparse so if anyone would want to weigh in to help me give a final verdict it would be greatly appreciated. But all and all a very interesting character, particularly the magical approach to superspeed rather than the usual tapping into the Speed Force.[/quote]

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.

Excellent points. I am not fightinging the ideas, but I am discussing the ideas.

Does anyone know what impulse' or kid-flash' speed is? 
 
No whirlwinds, no phasing through solid matter, no speed force, no '1-mile-mach-1' punches.

as for running on water:
To avoid sinking, you need to generate thrust equal to your weight. You generate this by pushing water down and backwards with each step. For a size 9 shoe, you can’t push more than around 3.5 litres of water at a time or you would sink too far and friction with the water would slow you down too much. 
So that 3.5 kg of water has to be pushed back fast enough to offset your weight. If you weigh 75 kg, my back-of-an-envelope calculation suggests you’ll need to push it back at around 11 m/s. 
Since the water moves back as you push it, you need to go twice as fast as that or you would stand still. So that’s a running speed of almost 80 km/hr, which would be quite impossible even in my idealised calculation that ignores things like fluid drag.
80 KPH = 49 MPH.

You are correct that 6000 BPM is a MASSIVE assault but I don't think anyone would let him get away with that much of a pounding uninterrupted. perhaps he can only do them in small bursts of a few seconds at a time as he is still coming into his power.

An even easier nerf-for-now is to drop him back from 10X to 2X or 3X for right now and as this progesses, he 'unlocks' more multipliers as he trains over each story arc.

I have no trouble with the boots only doubling his LAND based speed, and he might use them to get to places quickly with a snap-release. The easy answer is his feline physiology is already emulating this device as shifted bones and tendons which the inventor even said he got the ideas from, its like shooting an arrow from a crossbow launched from a bigger crossbow.
