Alien Role-Play (Heavily Inspired by Invader Zim)

Ok, so, we're going to create an Invader Zim ripoff through a role-play. If you ask, you might be able to make your own alien species; I will stop letting people make species once I feel enough have been made, so that we don't make too many.

(I'm calling them Ripoff Insert_Name_Here until we make the characters.)
We start with our protagonist, Ripoff Zim being sent to earth with Ripoff Gir. We then switch to our antagonist, Ripoff Dib, finding out that aliens are coming somehow. Slight time-jump and Ripoff Zim and Ripoff Gir are making their disguises and base. Larger time-jump and Ripoff Zim and Ripoff Dib are in school together. Hijinks ensue.

Ucheko

Ucheko are cat-like aliens from the planet Tatakai. Their bodies are described as "centaur-like with fur all over them". Their fur is usually black, white or yellow (like a lion) but can be died any color in the world. Their eyes are cat-like, and the lightest color on them match their teeth. They wear only tops as they find pants unlikable.

Name: Heiwa
Age: 14 (Both Human Years and Ucheko Years)
Species: Ucheko
Gender: Female
Personality: Heiwa is a hyperactive and kind young Ucheko. She tends to talk a lot and will try her best to make people feel better.
Appearance: https://drive.google.com/file/d/1ze7c5FyiBtpCk9BllMJ9eEohFJdVjvSs/view?usp=sharing (though it doesn't look like it in the drawing, her hands do have appose-able thumbs)
Other: She didn't come from a good background, so it's a wonder she came out okay.
