Here is mine for an example and I will actually use this one.
Name: BloodStone but also just goes by Blood
Age: 1700
Gender: male
Gem or human: gem
Side: Homeworld
Gem: Bloodstone :3
Looks: Black armor with deep red scratches on it, red skin, light grey eyes and short black hair. Is rather tall and well built, and has a scar on his right cheek.
Weapon: Black sword that glows red through cracks.
Personality: Vicious, almost completely detached from emotion, and will carry out any order given to him.
Backstory: Bloodstone was made for the sole purpose to keep Earth in Homeworld's possession and must follow his orders of taking out anyone who stands in his way or his gem will be shattered.

And also a human that I will use.
Name: Regan Nevelee
Age: 16
Gender: female
Gem or human: human
Side: Crystal Gem
Gem: n/a
Looks: Short and frail with rich brown straight hair that reaches her shoulders and deep brown eyes. Wears a stealthy suit of armor that is a dirt brown to help with camaflouge. She will wear just a plain white shirt and green shorts when relaxing or not in battle.
Weapon: Crossbow with a little bird carved into it
Personality: Is pretty sweet and motherly once you get to know her, but usually to outsiders she doesn't show concern for them and is very military in her actions.
Backstory: Regan is an only child and lost her mother and father in the panic of everyone fleeing and so decided to try to fight to save her home world instead of run like everyone else.
