History:
Nothing is known about the villainous Sponge before his first confirmed appearance as a member of the Honor Society. On Thursday, March 9th, 2000, a group of super-powered indiviuals broke into Intellidyne Ltd. in Boulder Colorado. The reason for the beak-in remains unknown, but this team of expert thiefs match the power set of a known criminal breaking-and-entering team calling themselves the Honor Society. This Society has a reputation amongst various police agencies, but was never confirmed seen before the Intellidyne break-in. While in the midst of this break-in, the Honor Society was challenged by the fledgeling superhero team known as the Phoenix Company. The society members, including Sponge, fought the Phoenix Company to a standstill, then escaped capture. At the time, it was believed that the Society's goal was to steal the design for a prototype computer processor, however this was not the case.

Unbeknownst to the Phoenix Company, the Honor Society had managed to capture Brad Stinier, a bio-engineer employed by Intellidyne, for reasons unknown. Given the Honor Society's track record, it is highly likely that the Society has given Stinier to whomever hired them for the Intellidyne break-in. The current location and status of Sponge and the rest of the Honor Society is currently unknown.

Unusual Features:
Sponge has blue tinted skin. His skin is naturally a shade of light blue, but gets darker the larger he grows.

Strength Level:
Appears to have average human strength proportionate to whatever size ratio he possesses. Note: When Sponge grows, he increases his strength and reach proportionate to his size.

Skills:
Sponge has shown no appreciable skills.

Known Superhuman Powers:
Sponge has the ability to absorb kinetic energy directed at him and rechannel that energy into an ability to grow. His maximum height is unknown, but theoretically he has a limitless growth range as long as he is supplied kinetic energy to feed from. Sponge also tends to go into a berserker rage when physically attacked, which makes him the ideal brick. Though Sponge's height, density, and strength increase, he does not have superhuman strength and density beyond his proportional mass (i.e. he can still be affected by damage done to him).
