* The Chaodyn in ''Literature/TheDeathGateCycle'' are monsters which, if wounded, their spilt blood will turn into another Chaodyn. The only way to stop this is to deliver a wound that kills them before any of their blood hits the ground.



* The show ''Series/AgentsOfSHIELD'' shares a continuity with the ''Captain America'' film examples above. Coulson [[spoiler:takes down HYDRA by basically cutting off as many heads as possible and, when he gathers enough intel, he calls in the Avengers to deal the final blow. Hydra is now scattered and Kelbo says that "heads ain't growin' back". Then Ward decides to revive HYDRA in his own image and recruits Baron Von Strucker's son as his apprentice; two more heads have grown.]]

All known heads are again cut by the end of the third season, including Hive, the original head. Of course, it's still possible that more will turn up in season four...]]

* The Disney adaptation of ''Disney/{{Hercules}}'' had Herc face this problem when fighting the iconic multi-headed serpent. It starts with one head, but when Herc chops it off, ''three'' grow in its place. In desperation, he starts wildly chopping at the beast, leaving him with a bigger problem than what he started with. However, he soon triumphs by causing the chasm they're in to cave in, [[RockFallsEveryoneDies resulting in the Hydra being crushed under a rock slide.]]

* Creator/{{Nintendo}}'s attempt to ban cartridge dumpers and copiers in the 90s: They started by targeting the most prolific manufacturer of cartridge copiers, Bung Enterprises. They went as far as to get an injunction on Bung Enterprises merchandises in the US. They managed to kill Bung Enterprises shortly after, but then numerous manufacturers then sprung up in Bung's place. Additionally, the amount of negative publicity generated resulted in the StreisandEffect (the US Customs also received a number of eggs on their face after they confiscated a package from Bung Enterprises meant for a US customer, and it turns out that the package only contained a GameBoyAdvance link cable), which affected the popularity of their consoles a bit. The funny bit is, Nintendo never learn. They later did the same things with flashcarts, with predictable results, and then they went over the MoralEventHorizon by trying this with ''Website/YouTube videos containing their characters'', again with predictable results.

*** There's also a classic math problem involving hydra ''herds'' in which every blow which fails to kill a hydra spawns a number of duplicates of the damaged hydra equal to the number of blows which the entire herd has received. (Added to that, Heracles is cursed to only be able to smash heads in the worst possible order.) Still beatable by an immortal demigod, but it's surprising how quickly the required number of blows grows.

* Most directly related to the mythological hydra, if a planarian's head is split without severing it from the body (not that they can't survive ''that'') both halves can regenerate, ending up with a two-headed planarian.
