Dex Hamilton Alien Entomologist

Dex Hamilton: The titular protagonist. Dex is an intelligent alien entomologist with a great love for insects. He runs The Habitat, where he and the others maintain a large variety of different habitats in which they can observe insects they've captured for study.
Zap Monogan: A human/insect hybrid found by Dex a few months before the series. He has a very laid-back attitude which can sometimes get on the others' nerves, but in a dire situation he'll always drop the act. He's the strongest in the group, and can grow insect wings that allow him to fly. He's also the group's pilot.
Jenny 10: Created as part of the 'Jenny Project', Jenny 10 now works as Dex's mechanic at The Habitat. She maintains the insect's habitats and builds the weapons used by the team to capture new bugs. She's always known that she was part of the 'Jenny Project', but she only told the others when Jenny 8 showed up.
Tung: A human/frog hybrid from another planet. Tung tends to have disgusting hygiene habits and strange taste in food. He can jump long distances and scale walls with little effort, and also has a long tongue, hence the nickname. He sometimes gets in trouble for eating the insects captured on a mission.
The Habitat: The Habitat is a large technological complex that houses all of Dex's insects. It was funded by the Mayor of Metropolis. The Habitat is composed of a matrix of special holding cells that simulate the insect's natural environment.
