* GameBreaker: ''Franchise/{{Batman}} Fluxx'' has the Batmobile and Batarang Keepers; the Batmobile can be discarded from play to take an extra turn, and the Batarang can be returned to your hand to put a card from the discard pile on top of the deck. If you get both at once, no one else will ever get a turn again.
* SpiritualLicensee: As mentioned in the Laconic Wiki page, it's the closest we can get to a tabletop version of [[ComicStrip/CalvinAndHobbes Calvin]] [[{{Calvinball}} Ball]].
