Powers: 
-Hyper Intelligence
Equipment:
-'Tin Man' Powered Assault Armor: Roger, using his expansive intellect, has constructed himself a suit of powered armor which he uses for his engagements as Tin Man. The armor amplifies his strength ten fold, he can't lift a tank or throw a car, but he can dish out some strong punches. It also doubles his running speed, so while he can't exactly run at superhuman pace he will out speed the average man. His armor also greatly diminishes the physical strain of activity on his body, so he'll usually be able to contiue without the effects of fatigue for longer than most. The armor's armor plating also allows for enhanced protection, granted, while the armor would protect him from small caliber bullets at decent ranges and large caliber shots at longer ranges, bullets still have the capacity to get through. His armor also allows him to take a few punches form targets with super strength or other physical enhancements, but not very many.
The armors offensive options are a wrist mounted grenade launcher, with four grenades ready to fire. Granted, between engagements he needs to reload these. On his left glove are electric shock plates which will do about as much damage to someone as a modern police issue tazer, making it useless against armored targets and somewhat useful for frying exposed machinery. On both wrists there are also twin hidden blade mechanisms. And of course on his armor's magnetized thighs(magnetized to allow him to store weaponry) are his twin pistols.
From a utility perspective, Roger's armor has several helpful options. It has magnetized boot and hand plates that can be activated and deactivated to allow for scaling(albeit extremely treacherous scaling...) of metallic structures. This armor also has rocket boosters on the shoulders and boots of the armor, allowing for extremely limited flight. He can't go very high, and and fly about twice as fast as he can run with his armor on. The jets fuel supply is also very limited, allowing only for short flights.
-Twin Pistols: Roger has two pistols, which he usually keeps on the magnetized thigh plates of his armor.
-Trench Knife: Roger keeps a trench knife tucked away in his belt, just in case.
Personality:
Roger is a generally friendly fellow, liking to make and keep friends. He's quite the talker and enjoys discussing any kind of subject, but he especially loves talking about technology. Roger is very accepting of others, as he was raised to treat others as his equal. Roger has trouble understanding why people would want to be different religions or sexualities, but he forces himself to accept it. He likes making jokes, although whether his jokes are funny or not really depends on the person.
History:
Roger's real parents are unknown to him, and he spent the majority of his childhood in an orphanage. The key figure of his childhood was probably a man he called "Father Clark", a jovial black fellow who worked for the orphanage and cared for the kids. Clark taught him to treat everyone equal, no matter their color or anything else about them. He was eventually adopted by a normal american family, the father of said family happened to be a mechanic, but Roger would always miss Clark. As his new father taught him about engineering, Roger quickly discovered his power. He could builds things and process information at rates most adults and the other boys and girls in his class couldn't match. As he got older his mind only got more powerful. But as he grew older and new forms of fiction came about, Roger took a liking to taking a dime and going down to the shop to pick up tales of comic-book heroes, like the new 'Superman' character.
When Roger heard of the war, he decided it was his duty to be like Superman, and aid the effort. He constructed himself a set of armor and managed to get the military to insert him into a special meta human unit, all while keeping his identity a secret, hiding behind the self-chosen alias of 'Tin Man'.
