Name: Jacob Jr (Known better as Jake. I also hope that you don't mind me using a different name.)
Description: Jake was always the image-conscious brother out of the two, and tried to look his best whenever he was doing anything. He had classic good looks, and was rather muscular, as well as tall, measuring about 6'3". His brown hair almost always seemed to have gel in it, spiking it upward. Jake had to wear glasses as well, but elected to wear contacts instead, covering his brown eyes. Although the resemblance between Jake and his younger brother, James, can be seen, the overall appearance of the two are vastly different.
History: Jake seemed to be the lucky one of the two brothers growing up. He was able to fit in with the popular crowd in high school due to his good looks and athleticism. Part of him always felt bad that he was accepted, and his brother wasn't. He would have helped him out, but he didn't want James to be made fun of even more by the fact that his older brother had to fight his battles for him. Jake is now in the same college as James. Although he wasn't as smart as his youger brother, he managed to get in due to a football scholarship. Jake shows his funny and outgoing personality more than anything, while hiding his true thoughts so that he could maintain his macho image. His brother and father are the only ones that know the real Jake. He seems to be trying to make up for lost time with his brother, trying to help him out whenever he could. Jake knew that, due to the fact that he was so liked, he'd be looked up to by James, but at the same time be hated by James for being a typical jock.
