Bibuteen

Bibuteens are a humanoid species that resemble Bibu from a French animated short film, Pink Sword of the Bibu. They are completely made in style of what they look like in that film, they are all teenagers, and they don't age at all, so they keep themselves 100% teenagers. Their sword is very unique that they had an iPhone-like phone that they only had one function, turn itself into a pink sword that looked like what it looks like in a film, and they even wear modern casual wear, even if the rest of the world is in its old times as well (especially when the first ones were there in 5000 BC).
