"Goofy looks" were the result of many things, including lack of sophistication in tooling, translation from sculpture to final product materials, lack of budget for detailed paint ops, modifications to be kid safe, and so on. But I don't think the original MotU designers ever intended the figures to look goofy . . . it simply couldn't be helped.Also i don´t think that more alterations and overdetailing does mean that the sculpts are more serious. If something is serious or not is very subjective. A figure could be also seriously goofy
I admit Fang Man is a little goofy, but thats what he should be. Don´t make something of him he isn´t. Goofy looks were always part of MotU, thats part of the fun i guess
The characters are already inherently goofy enough without embellishing it on purpose IMO.
