Painted BMW blue, with white trim. "Mk40-B" is printed on the right shoulder. Bruce, being a stickler for stats, has data printed on the various parts of the machine. Force output on the arms, the maximum thrust from the boosters, that sort of thing.

Years attended TSA: 0, first year. 
Bio: Bruce got a motorbike for his sixteenth birthday from his mechanic father. He immediately fell in with a rough crowd. Fighting, street racing, even petty theft and public intoxication were all under his belt by his eighteenth. He changed his tune when his best fiend wiped out and Bruce watched him die as they waited for the city's overtaxed paramedics to arrive. 
Bruce turned over a new leaf, but his best skill was racing motorcycles. So he raised the money for an entry fee and put together a proper machine to try his hand at an organized track race. He won and has been doing that ever since. He donates every penny of his winnings to rescue organizations, and that is what attracted Tony Stark's attention.

Skill/Ability: His suit has the highest acceleration and top speed, both in flight and on foot. The Blur is a remodel of Stark's Hypervelocity suit, the Mark 40, or the "Shotgun." It's been slimmed down some, to reduce weight and drag in flight, at the cost of some of the weapon systems. The only weapons left are the repulsors, which are exceptionally strong on this model of armor, as they're used in its hyper velocity flight. The repulsors can get the Mk40-B up to Mach 6.2, but as soon as it reaches Mach 5, a pair of scramjets mounted on the back can take over. The scramjets are housed inside of the armor, and when the required velocity is met, they can be extended and activated to almost quadruple Blur's speed. The jets run off of an experimental hydrocarbon fuel developed by Stark Industries, which is housed in several tanks on various parts of the suit. This fuel is much more limited than the repulsors, and it must be used sparingly. 
The spare processing power that isn't being used for targeting is now put to use as a flight guidance system. It gives advanced proximity and collision warnings, so that Bruce has enough time to react to things that he won't necessarily have enough time to actually see. When at full speed, Bruce relies more on chimes, whistles, and his heads-up-display than he does on his vision, which is basically, well, a blur. 
With a top flight speed of Mach 24, the Blur rivals some of NASA's experimental aircraft.
When anywhere above Mach 1, the shockwave that follows in Blur's wake can be used as a weapon. Bruce just has to fly near something for the wave to hit it. The greater the speed, the more powerful the shockwave. 

Personality: A real thrill seeking party boy. Kind of a daredevil, but he's confident in his abilities and they usually pull him through okay. 
Relationship?: none yet. 
Other:
A racer and a mechanic by trade, Bruce considers his position at Stark Academy to be the next step in both.
