Fisk's Superheroes is a mod by Fiskfille that adds superheroes and villians from Marvel, DC, and customs.
The mod allows you craft suits of both heroes and villains from across both DC and Marvel universes as well as some other movies and tv shows and the suits give you the powers of whatever superhero's or supervillain's suit you are wearing.
Depending on the hero or villain's suit you are wearing, you could gain the power to fly, stretch, use ancient magic, run at super speeds, change in size, and tons more.
