Some pre-evolutions I designed for the other Legendary Warriors from Digimon Frontier.
Faemon is the rookie warrior of wind. She is an effeminate butterfly/fairy with balloon pants. Drawing breasts on her is forbidden, but flowers and grass braids are welcome. Her name comes from "fae", another term for "fairies", and is derived from her adult/champion level, Fairymon.
Kriegmon is the rookie warrior of thunder. He's a spunky little cybernetic beetle with access to unstable amounts of energy. His name derives from "blitzkieg", an intense method of warfare involving speed, surprise, and powerful attacks on the enemy. It is also a play on the name of his adult/champion level, Blitzmon.
Cubmon is the rookie warrior of ice. He's designed after Japanese preschool outfits of rain hats and rain boots, as well as possessing a color palette of primary colors.
Halbermon is the rookie warrior of darkness. His design is a foil to Strabimon, with lion-influence rather than wolf. Though not bound by blood, he loves him like a brother, and their bond is still very strong. His name comes from the german word for "hallow" in "All Hallow's Eve" or "Halloween".
