Tesseract lives with on a planet of volcanoes and ice that is constantly at war. He hates this but has no choice but to fight. His weapon of choice is the hourglass staff filled with black volcanic sand, which he breaks in half and holds in each thumb and uses the rest of his hand to control. If he can just subdue or confuse others, that's what he prefers but he will kill if he has to. He's known to use it for creating illusions as well, making others think they are more of the army than there actually are, misdirecting attacks with sand figures, etc. He can also control the sand figures for short distances.

He is truly loving with those he cares about but the one he loves wholeheartedly resides on earth. They were separated when they were reincarnated from their past lives. He knows they can't be together, but he still longs for her and wishes she was by his side. He is not allowed to visit her like he was allowed to in their previous lives, and it hurts him greatly. He will often scry in large bowls of water just to catch glimpses of her and visit her in her dreams. Despite being so in love with her he wants her to find love where she is. There are a few others he considers like family, but he mainly keeps to himself.

He is tall, 6'7", with an average body shape. He has a large scar that runs from his neck on the right side down across his chest and hooks around his back. It wasn't an injury sustained during battle but brought on him by his peers for disobedience for communicating telepathically with his love. He has not forgotten this.

He has six eyes. The bottom two stayed closed unless he is using his sand magic. The top two eyes are rust orange with no pupil, the middle set are the rust orange with brown and have pupils. The bottom two, activated with magic use, look like a galaxy. He can grow his hair out but keeps it smooth (Anubis like) on his body except for some hair along his jawline and chin. His love told him he smelled of shooting stars. His voice is deep, rumbling, sounds like thunder.
