Many films and television programs are entertaining in and of themselves, having a large fan base. Occasionally, the makers of these shows decide to crossover, resulting in an exciting and crazy occurrence for fans. Regrettably, not all of them are great and provide as expected. Here are the top wackiest crossovers of all time:

1. The Rock and Star Trek

The Crossover episode with The Rock on Star Trek Voyager

That isn’t a joke, by the way. This bizarre event occurred in the Star Trek: Voyager episode “Tsunkatse,” which aired in 2000. It was partly due to the fact that Voyager and WWF Smackdown both drew enormous audiences for UPN, which led to their merger. Seven of Nine is kidnapped, imprisoned, and forced to battle in an arena against the Rock, a.k.a. Dwayne Johnson, in this odd episode. As strange as this event was, it was one of the first occasions Johnson acted in a way that wasn’t typical of a wrestler. His significant bit in this act was a foreshadowing of greater parts to come.

2. Ed Sheeran in Game of Thrones

Ed Sheeran as a Lannister soldier on Game of Thrones.

*Spoilers ahead* I mean, what was the point of that? His character was only a random Lannister soldier with a single uttered line of speech, and he didn’t do anything with it. It’s a shame, because this was such a crucial sequence! This scene, which came nearly soon after the Freys’ killing, was meant to test Arya’s entire kill-all-lannisters mentality. However, as soon as Ed Sheeran comes, the scene’s subtext changes completely to just focus on the celebrity crossover.

3. Mr. Robot meets Alf

Mr Robot and Alf crossover

The crossover episode on Mr. Robot with Comic character Alf.

Fans of “Mr. Robot” are used to unexpected twists and turns. Even still, the episode with a cameo from 1980s comedy extraterrestrial Alf was unquestionably the weirdest of them all. To be accurate, the entire thing is really a hallucination that occurs in Elliot’s head. A comatose Elliot thought up a weird daydream of his family on a road trip in the style of a cheesy ’80s TV sitcom while hospitalized after a brutal beating. A retro USA Network opener, a Full House-style credit sequence, and an appearance from Alf were among the highlights. You can’t dispute, though, that mixing a brilliant computer programmer with a fuzzy extraterrestrial dude who loves to devour cats is strange.

Undeniably, everyone enjoys seeing their favorite characters from one TV program, movie, or comic cross paths with their favorite characters from another. Even better if it leads to a fiery confrontation. However, it is recommended to the movie makers to give a second thought to some of the weirder ideas they might have.
