There are a total of 22 heroes in the game. There are five free heroes: Ant, Spider, and Beetle are the originals, Praying Mantis was added in a contest and Fiddler Crab Renegade was added due to popular request. Fly and Ladybug come in the "Death from Above" DLC, Grasshopper and Stickbug in "The Grandmasters" DLC, and Worm and Termite in the "Locked 'n' Loaded" DLC. Finally, each hero has an alternative version which has a different skin, different "level up" skill and other small tweaks. This adds another 11 heroes.
