[Crossover] I'm Not a Slime!

Hello, everyone. I'm an utterly ordinary Gumball, the first to conquer every map. I brought along the underlings I'd recruited along the way, retired to Gumball Village, and dropped off some local specialties, a bit like fairy water, for the neighbor lady. Then I suddenly discovered a new space-time imprint near the village. Wow, has another gate opened somewhere? I soon arrived in front of the gate and walked right past it without even looking. What are you thinking? Did you really think I was going to go in? As a retired, utterly ordinary Gumball, there's no way I'd go in! But this strange space-time gate wouldn't leave me alone. It kept appearing wherever I stopped. Heh, did you think my maxed-out evasion was just for show? I'll show you what real skill looks like! But this gate was clearly a sneaky little punk. It suddenly grew bigger, and before I knew it, I'd been swept into a sea of stars! "Aaaaaah! I haven't given the lady and the gentleman their specialties yet!" I flipped off the slowly closing gate (though my round little Gumball hands made it hard to tell), hoping the little punk would learn to behave next time. The protagonist is the original character from the game Unusual Maze. I played it in middle school, then uninstalled it. I thought of it again recently, so I decided to write a story about him. The protagonist is strong, really strong, especially, especially strong (I'm saying it three times because it's important). The pairing is undecided, and there may not be one. Usually, the protagonist is the bottom. He has a human form, but if possible, he'll usually curl up in his Gumball form. Theme: I'm not some weak little monster like a slime!
