Describe your Mermaid OC once. After that it is the same character every time.
Post your Mermaid OC. Other people can draw them too and send them back. Or keep them to yourself.
Happy, angry, sleepy, shy. The same character, every mood.
Tap an outfit and they put it on. Same face, same hair, same character.
Where they are from, who they lost, what they want. A story about your Mermaid OC, not someone who just looks like them.
A rooftop at night, a classroom, outer space. They still look like themselves.
Dive into the GenTube feed and see the merfolk other creators are dreaming up.
A mermaid OC is your own original character with a fish tail and an ocean story. Unlike a canon mermaid from a movie or show, your OC is yours: you choose the tail shape, scale colors, hair, fins and the underwater world they call home.
Just describe them. Tell GenTube the tail color and scale pattern, the hair, the eyes, and the setting like a coral reef, a deep bioluminescent trench or a moonlit surface. GenTube turns your words into lush aquatic fantasy art in about two seconds.
Lean into the details that make merfolk art pop: iridescent or opalescent scales, flowing hair caught in the current, soft underwater light rays, bioluminescent glow and an ethereal, dreamy mood. Add words like shimmering, pearlescent and deep-sea and the style follows.
Yes. The maker is not just for classic mermaids. Make a merman, a siren, a deep-sea naga, a koi or jellyfish hybrid, or a whole royal merfolk court. If you can picture the tail and the world, you can create it.
Yes. You can create as many mermaid OCs as you want, free, with no credits and no limits. Iterate on the tail, swap the colors and try new ocean worlds until your character feels exactly right.
Of course. Post your mermaid OC to the GenTube feed, and anyone can remix it into a new pose, a new reef or a new color scheme. Remix other creators mermaids too and watch a whole underwater world grow from one character.
