Cheetor

Cheetor was known to be the first major robot mode to actually torment Waspinator. During the Mario, Sonic, and Mega Man at the Beast Wars short known as Kid Puss, he scolds Waspinator, forcing him to remain a kid which he gets heavily annoyed from (despite him enjoying the milk in the bottle that he feeds him). As soon as he was through he left the room for a couple of seconds, only for Waspinator to get tormented by Rattrap, who had been watching the entire time. Waspinator is stopped just before he could catch Rattrap, from the words of an angry Cheetor. Waspinator's head was stuck in the dollhouse, and was yanked back on to his bed. Cheetor warns him that if he moved from his spot one more time, he will feed him castor oil, in which filled Waspinator with fear. He tosses him his bottle again before leaving out of the room a second time.

But Rhinox punished by her, he kicked him out.

During Cheetor's absence, Rattrap once again took advantage of the situation and called a bunch of wasps who invaded her room to torture Waspinator. Things for Waspinator took a turn for the worst, but, Cheetor soon returned forcing all 3 wasps to flee. Cheetor enraged is later shown feeding Waspinator the castor oil, who he struggles to oppose, but broke out when Rattrap Snapped his tail with an iron nutcracker, forcing him to swallow a large spoon full of oil and seconds, Feeling very sick he races out the window and starts to vomit. Rattrap laughed enjoying the moment at first, but a large drop of castor oil had later poured down onto his head causing him to vomit as well.

He made a cameo appearance in the Mario, Sonic, and Mega Man at the Beast Machines episode Don't Bring Your Pet to School Day, where he is shown bringing Waspinator into her elementary School with him looking more annoyed than he did in 1943. He then informs him to behave or they will not win the gold Star for the best pet.

Waspinator, however, is unamused with this competition and went as far as to remove his bow and hairdo that Cheetor gave him off-screen before the episode began. Waspinator then gets greeted by bunny, who begins to shake his hand while talking in a strange accent, which gets Waspinator even more annoyed. He then sees Rattrap being transported by a cage by Cheetor's classmate and friend Dinobot. Cheetor fawns at the little mouse, and claims to him as being adorable. Waspinator is amused and continues to eye Rattrap, on both revenge (Mostly for humiliating him In 1943, to the other wasps, and having him drink castor oil), and hunger (Mostly cause of him always wanting to eat him of course.), he then remembers that bunny is still shaking his hand. Finally snapping, Waspinator grabs a Mace from out of nowhere and strikes the bunny in an unknown part, and goes after Rattrap causing him to shriek in panic.

He is stopped by Cheetor, who is outraged on his behavior and demands that he apologize to him at once. Dinobot holds Rattrap in front waiting for Waspinator's answer. At first, Waspinator doesn't reply or do anything. Cheetor insisted again, forcing Waspinator to kiss Rattrap's head in humiliation and annoyance. He then does so twice (Mostly due to him enjoying the taste) and later begins to suck on his head. He then eats the little brown mouse whole but is tossed on the floor by an angry Cheetor. "SPIT HIM OUT!!!" He ordered, slamming him on the floor multiple times until he finally coughed him up. Cheetor than drags the naughty Waspinator Wasp away, and warns that If they don't win the star, he will take him back to the pound.

Horrible images of the pound haunted Waspinator, causing him to gulp violently. It wasn't long before he was tossed back to his chair, where Bartholomew is shown with 3 large bumps on his head dazed from the pain. Cheetor than points at Waspinator's Nose and demands him to stay put and be nice to the other animals. Waspinator shows a hysterical marking the words, "Yes Ma'am" In his eyes. Rattrap like back in 1943, strikes again and begins to torment Waspinator, with a drawing of him in the toilet. Waspinator furious gets up, but Rattrap points back to Cheetor, forcing him to sit back down in a cowardly way, despite her not shown when he points.

Rattrap than swallows a red apple whole, and goes over where Waspinator is seated spitting a large number of apple seeds in his face in a machine gun firing rate. Waspinator beginning to lose his temper, starts to growl. Rattrap responded by spitting one more in his face, which caused him to snap, but Rattrap points to Cheetor again doing her work causing Waspinator to cower in his chair again.

Rattrap then unleashes a frog and escapes the room with Waspinator pursuing in a panic state. He follows the 2 into the locker room, where he attempts to catch the frog, only to be suckered by Rattrap again. Before Waspinator could react the frog burped a third time, causing him to fly into the locker. Rattrap arrives with dirty gym clothes and begins to pack the locker leaving Waspinator locked up inside. A chase occurs throughout the entire school until it reaches the playground where Waspinator finally has both pets cornered. At one point he snatches the frog, but Cheetor arrives and demands to know what he has in his paw.

Waspinator on the verge of panic, took drastic measures and ate the frog, turning around facing Cheetor grinning he had nothing. Cheetor more angry, than disappointing grabs his tail and storms for the classroom revealing that they were next, which meant she had to search the whole school for him. During the presentation, Rattrap returns and torments Waspinator, again with releasing several of the other students' pets. The ants later crawl into Waspinator's fur making him scratch all over. The Frog jumped again, and soon or later Waspinator found himself caught in the Globe. "WHAT ARE YOU DOING?!!" Cheetor cried, with Rattrap laughing onto the Ant farm.

The Fire ants in his fur combined with the frog in his stomach caused Waspinator to do insane tricks with Rattrap still laughing in amusement. The Crowd, however, enjoyed the performance and applauded Waspinator, even with Rattrap joining in the applause. and Waspinator is shown In Cheetor's arms with the gold star. "You may not be the nicest wasp, but you at least got the gold star for being the best dancer," Cheetor said in her final words before the episode ended, marking the end of her appearance in the Mario, Sonic, and Mega Man at the Beast Wars series.
