The Barkin Twins - Timeline (of the Anthros)
When they were Kids:
When they were very young, they lived with a Tribe.
Their Father was from a Clan that used to be Demon-like before all of this Clan were killed by the Tribe of their Mother.
In that Time, Bruce`s and Jell`s Parents run away with them. Both of their Parents got killed. And so would have been Bruce and Jell if the Demon Blood wouldn´t woke up in Bruce and Jell.
All they remembered was Blood on their Fur. Their entire Pelt were almost covered with try, dark red Blood.
Since that, they were trying to find a new Home. But still the Tribe of their Mother was hunting them and they always found them. Bruce soon found out about his Demon Side and learned to control it.
Jell never really noticed it.
There were Werewolves. (woohooo for Randomness) So Bruce needed to hide his Sister when ever there was a Full Moon on the Night Sky.
