Mummy

The mummy's character: calm, reserved, silent.
He never talks, even if asked. Cold and calculating.

Why he doesn't speak, no one knows. His race can speak, but he's always silent. He does everything silently and methodically. He doesn't attack until he receives a direct order from his master.
Powers and Abilities: The Mummy is extremely strong and agile, allowing her to evade enemy attacks and deliver her own. She can split her body into ribbons and stretch them, allowing her to trap and wrap them around her opponent. The ribbons can also regenerate lost limbs. The Mummy also doesn't require oxygen and can even survive in outer space.

Mummy's first appearance was on a farm. She was sent by Victor to retrieve a dangerous element, Corrosion, which had crashed on Earth millions of years ago.

Max's device detected Corrosion at a refrigeration plant, where the Mummy was searching for another shard buried under concrete. Ben, as Diamondhead, accidentally unearthed it, after which the Mummy attacked him and took the shard. The battle rages. The Mummy mutates a security guard, who attacks Gwen and Max while she fights Ben. Using Plasma, Ben froze the Mummy in liquid nitrogen, and then buried her with Corrosion and covered her with concrete. The mutants returned to normal.

He was later released by Yenaldushi, a space werewolf belonging to the Loboan race. After his release, he assisted Ze'Sker in his plans to mutate Earth. At the spaceport where the Tennysons had arrived due to the purple lightning, Werewolf and Mummy attacked them together, and were later joined by Victor.

When Max and Gwen attempt to return to Earth on a salvaged ship, the Mummy appears on it, attacks them, and sends them flying into outer space. On the satellite, the Mummy attempts to send a corrosive beam to Earth, but Ben, in the form of Upgrade, comes to Max and Gwen's aid and sends her flying into space. During Ben's battle with Ze'Sker in space, the Mummy comes to his aid, but due to Victor's mistake, she is sent with him into the Null Dimension and is never seen again.
The Mummy has now escaped the zero dimension, thanks to Ben Tennyson's mistake, but he doesn't manage to stay free for long. Ben Tennyson captures her and imprisons her behind a special force field to prevent her from escaping. The Mummy is currently located at the Orderlies' headquarters. Orderlies' headquarters is the headquarters of Earth's orderlies. This operational base operates under the direction of Max Tennyson.
