Super deformed

Jim Henson's Decepticon Babies!

Super-deformed is a style of manga and anime art that features smaller, cuter versions of pre-existing characters, with distorted proportions.

• The G1 Mini Vehicles' alt modes were based on Choro-Q toy cars, which themselves were super-deformed versions of actual cars. (This is particularly clear when you compare Cliffjumper to an actual Porsche 924.)

• The Monster Pretenders featured rubbery beast shells and robot monster modes that were scrunched and deformed enough to be considered super-deformed (Scowl's bio in particular makes note of this horrid cuteness.)

• In 1990, Takara marketed a series of super-deformed Transformers toys, with the Transformer PD Type mini-comics serving as their official fiction.

• MyClone figurines are also designed in a super-deformed style.
