Catrouble

Catrable is the non-binary ship between Catra and Double Trouble from the She-Ra Princesses of Power  fandom.

Canon
Catra and Double Ttrouble met in season four when he shape shifted as Scorpia when she was leading horde soldiers and Scorpia into getting Hordak's equipment, Catra immedtly knew it wasn't Scorpia and asked who they were before Double Trouble shape shifted into her, surprising her and Scorpia. After going back to their normal selfies they introduce themselves and give their abilities to help the Horde with their plan as long as they get paid.

Double Trouble shape shifts into Catra as they meet Hordak, who is also surprised by their ability but tells them not to do it again to him.

Fanon
Double Trouble immediately gained fans after their reveal on the season four poster and trailer which showed them working for the Horde. It quickly gained shipping fans in season four as they and Catra spend a lot of time together and get alone quite well, they even give Catra nicknames such as "Darling" and "Kitten" and is touch-feely with her.

The two have respect for each other and Double Trouble often tried to get Catra to have fun, which they succeed in quite a few times, they also saved Catra's life which she genuinely thanked them for.

When Double Trouble "betrayed" Catra in the last episode there was no spite or anger, but the opposite. They told Catra that she wasn't evil and didn't wish to be, telling her that people leave her because it was her fault not theirs. Surprisingly Catra doesn't show any shock or action to fight back, rather shock and guiltiness; some believe that Double Trouble is the reason Catra will change and join the rebellion and finally get her redemption.
