12 [Similar Anime] Like Isekai Quartet

Both shows are crossovers of 4 shows containing similar attributes to them (all isekai's in IQ and all Type Moon works in CP) and both contain lots of parodies about their base shows. They both also require knowledge about the original shows, in order to get the most enjoyment out of them

Both are funny chibi parodies of their original shows, and both have a very lighthearted tone in contrast to their original shows (with the exception of Konosuba)

Comedical anime that parody multiple franchises and require knowledge of all included franchises to be fully enjoyed, but in turn rewards watchers with quality jokes and references towards the works parodied. It is also not only parody, but the actual characters trapped in a world that chibified them. Also check these out if you're a fan of chibi style animation.

Best comedy shorts. If you dont laugh watchin these get some help. Please

They both have a chibi artstyle made by the same animation studio. They both include extra interactions between characters.

Both good comedies. There is always some sort of violence in each that make me laugh, they also have similar styles :)

This is the sequal obviously
-Has better jokes than the first one.
-More Friendship and Teamwork.
-Makes Aqua "more" useful than ever before.

Although not quite similar in thematics both are parodies that make a prominent use of punchlines—even without seeing the original series you will laugh. I found Naruto SD more hilarious and absurd comedy than this one with outstanding episodes to more regular ones.

Parodies of a certain anime, redesigning characters into chibi form and making them play out comedic situations. Both have short episodes.

While Isekai Quartet is a combination of four different shows, there is no denying that the show feels very much like a Konosuba spin-off compared to the feel of the other shows.

While having no notable names due to the characters of Re:Creators are all original characters, both Isekai Quartet and Re:Creators have a similar premise of having multiple characters from multiple types of media and genres and having them all in one world and having them interact with one another.

Parodies of a certain genre (sentai/isekai) using characters of notable franchise of said genre with a chibi redesign. Both have short episodes.
