Soovar

Soovar is a Sea Devil soldier who joins the Doctor's army in the fifth episode of Season 4.

Personality
Soovar is a loyal Sea Devil who serves his fellow Sea Devils, until their base is destroyed by Morbius. After this, he joins the Eleventh Doctor and his friends to help them fight against Morbius and all the other threats to the Universe.

He has a tendency to get pretty emotional when he remembers that his fellow Sea Devils were all killed by Morbius.

Abilities
Being a Sea Devil, he is a very capable swimmer. His main weapon is a disc-like gun that fires a blast of heat. This can cut through metal and rock. Later in Season 8, the Sixth Doctor upgrades it so that it can cut through Dalek armor.
