Gets tied up by Meap ("The Chronicles of Meap") Is stunned by Isabella being extra cute and loses his own cuteness when he was the cutest thing in the universe.. ....or so he thought when he saw her.

Mitch, also known as Big Mitch, is a recurring antagonist of the TV show, Phineas and Ferb. He is an intergalactic criminal. Among his crimes are poaching various extraterrestrial creatures and imprisoning them aboard his clandestine space station, and attempting to seize absolute control over the galaxy. Deviously clever and highly elusive, Mitch has made himself known across the universe as a formidable threat. However, his plans are always brought to a halt by Meap, an experienced agent of an intergalactic security force, with the frequent assistance of humans Phineas, Ferb, Isabella, and Candace.
Heinz Doofenshmirtz painted a face on a balloon and sprayed it with a lifelong lasting spray when he was a kid. He named it Balloony. Though, one day while he was protecting the Doofenshmirtz family's garden while being a lawn gnome, Ballooney floated away. Later, Mitch found Balloony floating in space, called him his best friend and named him Colin.
During the Cutonium search
In "Meapless in Seattle", he was in a search the cutonium (a special element for becoming the cutest thing in the universe). As the cutonium fell into the Earth, he was attacking Meap on the way to Earth. When he reaches Earth, he attacks Phineas, Ferb, Candace and Isabella. He then goes to Seattle, Washington, where the cutonium fell, and Meap and his friends start digging where the cutonium may be, but then is discovered by Dr. Doofenshmirtz, who thought it was coffee, and as he drank it, he became cute and Mitch took Doof with him. In their home planet, he extracted the cutonium off of Doofenshmirtz. He then drank it to make himself the cutest thing that ever existed, so the other cute aliens couldn't attack him. Phineas got hypnotized by the cuteness when he didn't look away like, Meap, Candace, Isabella, and Ferb did. When Phineas came back to normal seeing Isabella, Phineas replies that she must confront Mitch, because the only cutest thing in the universe is Isabella. Isabella fell to where cute Mitch was by hanging onto a rope that was by her when she just got Phineas back out of the trance and said with an aura and echong "What'cha doin'?". This made Mitch to collide with a wall, making the cuteness fail for Mitch. He then tried to run away, only to be stopped by Candace, who threw a cell phone perfectly at a button, whih broke after it hit the button. Meap then said he'd get a 16 minute timeout. He doesn't appear in the credits, unlike The first Meap episode.
