Stad Facts:

They usually come in dark grey but albino Stads are pretty common as well. They can often have patched marble patterns of different shades of dark grey or white. Their eyes and glow come in any colour.

On all fours their head heights come to around 7 feet, and when sitting up on their hind legs they stand at 12 to 14 feet.

Amphibious they are as quick on land as they are in water. They need to swim around in water at least once a day to keep healthy when away from their home planet [which is mostly covered in water]. Without water dehydration is deadly for them and can cause permanent damage to their system.

They don't have any fur, scales or feathers, just skin.

Apex predators they are considered some of the best predators in the known universe.

They have wide long fins on the sides of their legs that help them swim but fold up when out of water.

An electric species they can generate 8,000 watts of electricity.
