Name: Xavier Lackie
Nickname: Gas Giant

Gender: Male
Age: 37
Species: Rat
History: Gas Giant is a skilled chemist who spent many years in-taking various poisons over the years till he became immune to over 274 types of poisons in Grah and Gina's world. But his studies didn't stop there. He also used his knowledge of Poison to create a special suit that allowed him to inhale, store, and exhale any type of poison stored in his body. In fact, he is not actually fat, his huge body is actually made mostly of gas build-up. He can even shape his body in several odd shapes when filled up. Although this is useless, it's kind of fun to watch.
Gas Giant has a bit of an ego on him. He has a good heart, but he often boasts about on how he is the most powerful of all the Elemental Force members. He was the first member of the Poison House, and originally was the captain of the Poison House, until Bobsled appointed the second member of the Poison house, Lizard Lips, as the captain. Gas Giant and Lizard Lips don't get along very well.
Abilities:
A: Fumigator: Fumigator displays his use of poison gas. Gas Giant breathes clouds of noxious gas which can deal a little damage and slow opponents down, making them easier prey to be punched into submission. He can also breath an entire ring of gas around his body. ...Did I mention his gas is also flammable? He can light a match to light his gas, which can cause damage to any opponent still trapped in a gas cloud.
B: Slime Ball: Slime Ball displays the ability his suit carries to liquify gaseous poison. His liquid poison is much faster, stronger, and longer ranged than his gas, but cannot hit multiple enemies. He can spit poison onto the ground as well, which hurts whatever walks onto it. He can also slide along the poison to turn himself into an uncontrollable wrecking ball that doesn't stop till it crashes into a wall.

Edit: Both Gas Giant and Lightswitch ended up getting the name "Ebenezer," and I think it fits better on Lightswitch, so I'm giving him a different name.
