Inside Doey were 3 kids. Who all became 3 in one body thanks to the experiment that happened to them...

Jackie/Jack the youngest only 5-6 was always happy and loved playing with his toys.! "Nyyoooow! A cat goes to space!" Jack says happily.

Kevin was the middle one and extremely angry and violent. He was 13 and always constantly lash out. "...I HATE THIS PLACE!" Kevin yelled angrily.

And finally Matthew. The eldest one by 15-16 years old. Gentle and loving. He takes care of the other two. Always making Jack happy and calming down Kevin. "Shhh...let's calm down Kevin..." Matthew gently said.

Whenever something happens that traumatizes them they all usually cry. But Matthew knowing Jack's the youngest hugs Jack in his chest while Kevin stubbornly accepts the hug.

Their Descriptions (Headcanon):

Jack appears as a young hispanic boy with short black hair, a lumberjack vest blue jeans and white shoes and a gap tooth.

Matthew appears as a tall teenage blonde boy with blue eyes and freckles, a white shirt, grey shorts, a blue sweater around his waist, tall socks and black shoes.

Kevin is an average ginger/red haired boy with freckles and blue eyes, a shirt and a jacket under his overalls, and shoes with a usual angry expression.
