The two cards you mentioned are indeed Superpowers, but more specifically they are Signature Superpowers, which only one specific Hero can use. Each Class has 3 Superpowers, each of which can be used by two specific Heroes. Examples would be Whirlwind, which can be used by both Green Shadow and Night Cap, and Super Stench which can be used by both Super Brainz and Impfinity.
