For someone who has a huge interest in pop culture and lots of franchises, it's really hard for me to pick something...
But I have an idea that might fly:
Mini franchise based on mine interest:
Courage the Cowardly dog is a (dark) comedy/horror american animated series made by John R. Dilworth (The person who founded Stretch Films studio) for Cartoon Network.
The show is about Courage, a small "cowardly" pink dog who defends Eustace & Muriel from aliens, monsters, ghosts, mad scientists, evil people and other abominations.
The show is considered as cult classic among the fans of the show (or even the CN fans as whole), but it managed to be popular due to use of surreal horror elements in the show, medium blending or writing.
Although now it's niche show, but still manages to be part of 1990's people's childhood.
Racers:
1. Courage
2. Eustace & Muriel
3. Katz
Items:
Oil Tank - Happy Plums
Tacks - Black Puddle Queen's black puddle
Flame Power - Eustace's mask (The player racer's head is replaced by Eustace's mask)
Exploding Traffic Light - Evil Carrot (From "Muriel blows up" episode)
Homing Missile - McPhearson Phantom (It flies straight at one of the players)
Dummy wheel: Bugle Monster (His design would be changed to make him less creepy) (The CGI trumpet slides across the track)
Speed Bomb - King Ramses & his slab (Ramses would swap the racer's place with different one)
Ice Crystal - Big Bob blasts (Horst's weapon)
Force Field - Clyde the fog spirit (Covers the user with it's fog)
(I planned to put Eustace's mallet somewhere, but I didn't know how, so I scrapped it)
I feel we need a CN franchise in the game somehow...
