So this was a doodle a while back for my mom and dad, showing them how their long awaited son looked like.
Don't ask about the tail really, just put it as he can twist it around a bit.

Anyways... I guess here's a ref for this kid.

Name: Thompson, Thomas, Tommy, Tom (( shortening names are fun ))
Age: 18
Height: 8'0
Gender: Male
Personality: A very happy and outgoing guy, kinda strong in a ways, always loved working with tech. He's not exactly the dominant type unless he's doing something not involving his parents.
Likes: Seeing people happy, taking care of his younger siblings, swimming, meeting other sharkies, milk, taking long walks
Dislikes: People who fish, anything that's not exactly raw, peanut butter, hitting horizontal poles from his height, dry areas
History/Backstory:

Soo, lets see... Tom started his life in, an orphanage? As a baby he was left at the shelter, where he was taken care of. It hadn't been about a year plus when the place was robbed, and some gunshots were fired, forcing others to flee. He was about 1 1/2 at the time, already knew how to walk, so he had somehow did his best to get away from the place, ending up in an alleyway.
Tom lived in the alleyway for a bit, not wanting to show his face to others. He ate the scraps of others food, till some couple went on a walk that day.
They found Tom in a trash can, which at first he was a bit fiesty and lashed at them with his teeth, but he ended up crying afterwards. So the couple decided to take this 2 year old boy in, and raise him up. Since then, Tom's gained a younger brother just a month after being taken care of, and by age 18, gained another younger brother and sister. His life consists of him living with his parents for now, but he's often found walking outside.

I guess that's it for him..? Meh, oh well~ First drawing of this guy, i'm alright with it.
