I thought of a random batch of some discs I would want:
MOUNT- Calhoun's Cruiser (Wreck-It Ralph) : Calhoun's Cruiser, obviously
MOUNT- Cy-Bug (Wreck-It Ralph) : A bit of a stretch, but you have to admit it would be awesome to ride around on a giant Cy-Bug! Or have a baby one carrying you around hahah
MOUNT- Hero's Duty Ship (Wreck-It Ralph) : In the event that Cy-Bugs are too ridiculous.
MOUNT- The Hydra (Hercules) : I am positive that this one will not happen due to how confusing it would be to scale reasonably, but it would be awesome
POWER- Glitch Teleportation (Wreck-It Ralph) : Teleportation to a different location
POWER- Hercules' Strength (Hercules) : Improved strength and defense
WEAPON- King Triton's Trident (The Little Mermaid) : General melee weapon
WEAPON- Superpowered Fire Extinguisher (Wall-E) : Mid-range continuous attack (sort of like a flamethrower, ironically)
THEME- The Lion King
THEME- Finding Nemo
THEME- Swamp from Princess and The Frog
THEME- Wonderland
+1 for Aladdin magic carpet, Steamboat Willie, and Kuzco Llama Gun.
