Think of the Powers in terms of Anime. So to me I equate speed with the following:<br/><br/>30 mph - For those in the "Run, Lola, Run" category. Runners who can't be caught by norms<br/><br/>120 mph - Fast car, fast bike types. Think Bubblegum Crisis<br/><br/>600 mph - Airborne Mechs, flying through space and the atmosphere<br/><br/><br/>As for Mind Control I believe it was stated eariler that it's a mental attack vs Talk. When damage reduces Talk to 0 you're considered under the control of the other character. Then, to resist commands you have to roll vs their Talk.
