Deadpool was currently wearing a bright green t-shirt with a giant number ten painted on it, while holding a half-eaten block of tofu in his left hand.
"tum, keep your eyes peeled and your DNA scanners ready, because Ring 22 is about to become a high-speed zoo!" Deadpool shouted, throwing the tofu at a passing camera drone. "This is the 'Shape-Shifter Showdown'! We have the wielder of the Omnitrix versus the greenest Titan to ever grace our screens! It's Ben Tennyson against Beast Boy! It's a battle of a million aliens versus every animal in the encyclopedia!"
Ring 22 was a sprawling, multi-climate biodome. A dense jungle abruptly transitioned into a rocky canyon, which then dropped off into a deep, saltwater lagoon. It was the ultimate playground for combatants who could change their form to match their environment.
Heimdall was hovering above the canopy on a floating platform. "Match Number Thirty-Eight! The universal savior, Ben Tennyson! Versus the changeling hero, Beast Boy!"
The Dinosaur Dance
Beast Boy stood in the jungle section, cracking his knuckles with a wide, confident grin. "Alright, watch and learn, watch guy! You might have some cool space monsters, but Mother Nature never loses!"
In a flash of bright green light, Garfield Logan vanished, replaced by a massive, roaring Tyrannosaurus Rex. The sheer weight of the green dinosaur shook the trees as he charged forward, jaws snapping wildly.
Ben calmly slammed his hand down on the glowing faceplate of the Omnitrix. "Mother Nature? I've got the whole universe on my wrist!"
A blinding emerald flash erupted. Where the teenage boy stood a second ago, a massive, muscular, brown-scaled humanoid towered over the trees.
"HUMUNGOUSAUR!" Ben roared, his deep voice echoing through the biodome.
The two titans clashed in the center of the jungle. Beast Boy snapped his massive T-Rex jaws, trying to bite down on Ben's shoulder. Ben simply planted his feet, caught the dinosaur's upper and lower jaws with his bare, scaly hands, and effortlessly flipped the giant green reptile over his shoulder like a judo master.
The Game of Tag
Beast Boy hit the dirt and instantly shifted forms. The massive T-Rex shrank down into a tiny, agile green peregrine falcon, shooting up into the sky to avoid getting crushed.
"Catch me if you can!" the falcon squawked, diving down to peck aggressively at Humungousaur's eyes.
"You want to play tag? Fine by me!" Ben slapped the Omnitrix dial on his chest.
Another flash of green light illuminated the arena. Ben transformed into a sleek, blue-and-black velociraptor-like alien with wheels on his feet.
"XLR8!"
Ben zipped away in a blur of motion, creating a localized tornado that sucked the green falcon right out of the air. Beast Boy spiraled out of control, quickly shifting into a heavy rhinoceros to drop safely to the canyon floor. He braced his horn, ready to charge the moment Ben approached.
The Final Grapple
Ben skidded to a halt on the rocky terrain, evaluating the angry green rhino. "Okay, speed isn't working against heavy armor. Let's try a little brute force and a lot of attitude!"
Ben hit the dial one last time. He grew rapidly, sprouting orange fur, black stripes, and massive claws.
"RATH!" Ben screamed, flexing his enormous muscles. He pointed a sharp claw aggressively at Beast Boy. "LET ME TELL YOU SOMETHING, GREEN RHINO MAN! RATH DOES NOT PLAY HIDE AND SEEK! RATH PLAYS SMASH AND CRUNCH!"
Beast Boy charged, the ground rumbling beneath his hooves. Rath didn't dodge. He roared, sprinting head-on toward the rhino. At the last second, Rath leaped into the air, caught Beast Boy by the horn, twisted his entire body weight, and slammed the rhino onto his back with a devastating suplex.
The impact cracked the canyon floor. Beast Boy reverted to his human form, completely dazed and groaning in pain, unable to move his arms.
Rath pinned him down, raising one massive claw. "RATH WINS!"
"Match Thirty-Eight winner... BEN TENNYSON!" Heimdall announced, wiping sweat from his brow.
Up in the booth, Deadpool tossed his number-ten shirt aside. "The Omnitrix outclasses the animal kingdom with pure alien muscle! That's 38 winners down, 13 matches to go in Round One, tum! The bracket is getting terrifyingly small!"
