Oh my god, I have so many characters for video game ideas it's not funny. More than I have for my various novel ideas.
A few examples, if I may:
Lady Kinsetamine the knight and her faithful dragon Arkady - two companions for a dual character platformer series based around switching between the two characters and solving puzzles. Drew some concept art and had the mechanics drawn out as well as level designs, but I scrapped it all several years ago.
Slash - ex convict and dog like space pirate who leads the Sirius corp. Set in a universe where stars are actually gods, some benevolent... some hell bent on wiping out all life. Sirius was the most notorious star-god. Was to be an action platformer ala Metal Slug and Contra but with heavy emphasis on leveling weapons and exceptionally high difficulty. Other characters included Kat (Feline katana wielding samurai), Klebol (Kobold mechanic), Winston (Peacock sniper), Fenix (Pyromaniac phoenix), Sins (Hydra heavy weapons specialist/priest), and Hammerhead (Robot artillery piece). Yes, it was weird. Didn't get far with this idea, only a few concept arts and boss ideas.
Kasey - a walking talking lobster who captains a pirate vessel. Was to be an RPGmaker game based around ship to ship combat, but I got bored trying to program a working tactical ship combat mechanic into the game. Other characters included a tree, a human trader, a steam powered robot, a sea dragon, a mermaid, a siren and a water elemental, all who could captain their own vessels/sea beasts. Adapting into a novel instead at some point.
FutureRaptor - a blue feathered time traveling velociraptor. Was to be the main character in an adventure game series that parodied Doctor Who, using the AGS engine. Concept art and most of the puzzles laid out, but that's about all I did before giving up.
