- Crimebreaker Six - like Bat-Man only less so
- Ultra Robo - the robot with the heart of gold, literally and figuratively
- Kamen Pilot Blue - master of vehicles
- Elfelf Princess Balina - the exiled ruler of the Fairy Realm
- Mecharider Sam - he has 60 tons of high-tech gadgets and he's not afraid to use them
- Chirubi the Chosen - unwilling wielder of a cursed blade
