Ben Braeden

History
Ben Braeden spent the first eight years of his life never knowing who his father was. The classic rock listening, lady loving Ben would soon meet his older counterpart in Dean Winchester, whom the boy felt would be a good match for his mother Lisa, especially after Dean saved both of them from a monster.

Three years later, Ben got his wish as Dean temporarily joined the family, secretly reading John Winchester's journal late at night while Dean and Lisa slept. Dean's life a hunter soon interfered and ruined things between Dean and Lisa, culminating in Dean having Castiel wipe both of their memories of ever having met Dean.

The next year was peaceful enough, but soon turned tragic when Ben and Lisa were attacked by vampires, leaving Ben comatose. When he woke up two years later, he found out Lisa hadn't been seen since that night. The attack also started opening Ben's lost memories due to the fact that Castiel only locked them in his subconscious just in case Dean ever wished to come back to his family.

Ben ended up falling in with a group of hunters led by Patrick Wheat, who looked upon Ben as a soon. When Adam and Samandriel arrived, the trio quickly bonded, just as a vampire attack killed most of the hunters, as well as Ben's girlfriend Prue, who had been the one to betray the hunters in order to find her missing brother Connor. Connor had already been turned by the time the hunters found him, and the vampire who turned him killed himself so that Connor could never be cured.

Ben decided to start hunting with Adam and Samandriel, quickly going on adventures together, eventually gaining another member in Jesse Turner. When Ben was critically wounded in a hunt, Adam sold his soul to save his friend, causing Ben to encounter the Reaper Cole, who knew about Ben's past.

When Jesse was captured by demons, Ben's memories were unlocked as a way to taunt him on top of the knowledge that Dean Winchester really was his biological father, causing Ben to go a huge depression, which increased his alcoholism. He was brought back down to Earth by resolving to help Adam save his soul, which resulted in discovering Adam had a son named Hunter.

Ben eventually got to confront Dean about erasing his memories as the two came to blows, but eventually started to patch things up slowly, with Dean allowing Ben's team of hunters access to the Men of Letters database.

Later, Ben would team up with Mr. Fizzles to start tracking down his mother, who was still alive and in the hands of the Alpha Vampire, with plans to kidnap Ben and reunite mother and son.

Trivia
Before Hunter's arrival, Ben's drinking and pot smoking were getting out of hand. It was only the boy's influence that caused Ben to start being more level-headed with a kid around.
