Asher Colby

History
Asher Colby's only real father figure in his life has always been his big brother Michael. Ever since he was born, it's been Michael that's looked out for him and made sure he grew up healthy.

When Asher was attacked by a Schtriga, it was Michael that sacrificed his own life so the Winchester brothers could kill the monster. Later when the demon Meg brought the Horseman Pestilience to town and made the children sick again, Michael was the one who fought back, at the cost of their mother and home. Asher was instrumental in defeating Meg, using the exorcism that depowered her possessed army.

After the brothers left town to find a new home, Asher fell in love with his adopted brother Mason. The two became a powerful hunting duo, and eventually planned to get married. Unfortunately a pack of werewolves had other ideas and murdered Mason, as well as several hunters, during the ceremony. An unhinged Asher went off and murdered virtually every werewolf that had invaded the ceremony, leaving Asher mentally broken for a while.

Fortunately he recovered in time to help face down the demon Dawn when she took over the town of Lawrence, Kansas. Asher resolved to move on with his life, although this resulted in him landing in an abusive relationship, which Michael quickly rescued him from.

In an attempt to find someone to keep Asher safe when he eventually died from a brain tumor, Michael tapped the witch Rowena McCloud to help fix Asher up with Adam Milligan. Although this plan failed, the two did share a kiss and agreed to eventually date when both had healed from their own tragic relationships.

Later, when Adam's son Hunter disappeared, Asher was put in charge of locating the boy as Asher was the only one left of Michael's group that Hunter had taken a liking to.
