User blog comment:PokemonTDHTF98/What if we have a HTF Crossover Episode./@comment-27169958-20160224103941

The crossover that would work best is HTF with D_Void. They have pretty much the same premise, rules and creator, so none will make the other jump the shark. A cross with something kid friendly will be bad for at least one of the shows. A cross with an adult cartoon that has more sexual humor can backfire too. HTF works best with animations that are kid friendly at first sight, but then splatter everything with blood and organs. Fanon crossovers on the other hand are less restrictive. We can have Elmyra from Tiny Toon Adventures squeeze one of the HTFs to death. That would be hilarious.
