I love Keroro Gunso so much to the point that I randomly doodled myself an OC during class using a cheap ass ballpoint pen and highlighters(and red colored pencil)
She's not a Keronian, unfortunately😅 She belonged to an alien race I made up where they looked just like ordinary animals from Earth, and they have this capability to morph themselves to whatever aliens they consumed(they're carnivores, sorry). If they eat a Keronian, they copy their DNA, and merge it to their own, making themselves look like a Keronian. I won't get to scientific with the explanations so that's that🤷♀
They'll still have unique features to set themselves apart from the race, and still be recognizable to their original natives. They hunt in packs, that's why.
And I ship her with Galulu.
