You could start with wacky characters who have exaggerated personalities or quirks. Maybe a superhero with a fear of heights or a talking animal with a human job.
One easy idea is to create a story about a character's dream. It gives you a lot of creative freedom to imagine strange and wonderful things. Another option is to tell a funny story that happens at school or in the workplace. These settings are familiar and can lead to many interesting plotlines.
You could do a comic about a talking dog that has crazy adventures in the park.
You could have a character constantly getting into comical misunderstandings. Like thinking a dog is a werewolf or something!
One funny idea could be a workplace comedy with oddball colleagues and their crazy antics. Another could be a story about a time-traveling dog that causes chaos in different eras.
How about a comic strip about a group of animals with human-like personalities going on adventures in a magical forest? There could be funny interactions and unexpected plot twists.
A comic about a superhero who has really strange powers, like the ability to turn into a marshmallow or make objects talk in funny voices. That would definitely bring some laughs.
You could do a comic about a talking dog who always misunderstands human language and gets into funny situations.
How about a story of a little kid who discovers a secret world in their backyard? It can be full of funny creatures and surprises. This idea allows for a lot of imagination and creativity.
You could do one about the crazy adventures of a group of friends during lunch break at school.
How about a series of funny misunderstandings between aliens and humans in daily life? That could be a hilarious short comic. For example, an alien trying to figure out how to use a human toilet and causing all sorts of chaos.
