[@Princeofhearts]For one, I'd tone down the scale of his powers. A fist-fight using super strength of 100,000 tons with flash-equal speed is over the top compared to most others if he went off the wall from mind control or some such. [u]most[/u] superheroes get super strength or super speed, not both. And tossing on super-genius intellect with full martial arts training.

Soft suggestion and suggestion only is to set yourself up with a personal level or point system and shift the things around to scales of strength, instead of starting off with arctic superbreath, make it 10 MPH and lower temperature by 10 degrees, you could freeze already cool objects around 40 degrees and kick up debris easily hands free. Then after some adventuring and training, ramp it up to 20 MPH winds and 20 degree cooling. When you reach huricane force winds the arctic breath will be just as easy to accomplish.

But teffinately drop the strength and speed to something like 10X a human of his height/weight, that's 100-120MPH and 2000 pounds or so. More than enough to be a superhero without being justice leauge material off the bat.
