He's very smart, but he's not a show off about it, and he is a very respectful person. He usually keeps to himself, because small talk isn't really his thing at all. He loves science, since he always liked to learn. He never did well with crowds, but he does likes to make friends.

As a forensic scientist, Barry is pretty good at his job, which is being a CSI. He usually finds out the case of murder one way or another, and he always keeps the look out for any potential evidence. Fortunately, he doesn't get sick at the sight of corpses, because he is an professional. His job is pretty easy for him. He's interested in things like the impossible, because his mother was killed by the impossible. He's a very generous person, and he understands what it likes to loose a friend or family.

As the Flash, Barry is very hyper, and a very cocky person. Also, he's. To be very different from his actual self, he acts the opposite of Barry Allen. He can be very serious at times, or a wisecracking hero at other times. He likes to run, and to run a lot. He likes the concept of being a hero, because he can help people more than he could as Barry Allen. He hates to kill, even though sometimes he has no choice but to do so. That being said, he doesn't kill much, because that wouldn't make him different from the people he fights.

Powers/Abilities: SPEED FORCE- The Speed Force was created by the god, Mercury. Anyone who has the power of the Speed Force is a speedster. Speedsters tap into the Speed Force to have the ability to run faster than the speed of sound. Leaving a trace of electricity for a brief moment behind them. They run so fast, that most people only see them as a blur. The Flash is one of the very first people that have been gifted the power of the Speed Force, because his future self ran so fast that he turned to lightning and struck Barry. The Speed Force can be also absorbed by the Tachyon Device. The Tachyon Device was used by Jonathan Fox, which gave him super speed. He became the Flash in the 27th century because of this.

TIME TRAVEL- Sometimes, speedsters run so fast that they time travel to the present or to the future. This happens rarely, because usually most speedsters cannot run that fast. Barry is not one of them, he has time traveled in multiple comics. Once, to save his mother which caused the Flashpoint Paradox, which lead to the New 52 storyline. Reverse Flash is also a speedster that has time-traveled, he is the speedster that killed his mother to hurt Barry.
