Jester Madkat Miro is the supervillain alter-ego of Miro, the fursona of G00da. He an anthropomorphic black panther standing 188 centimeters tall and weighing 84 kilograms.

Miro was a young panther until his soul became bonded with a jester box that had appeared on his doorstep, transforming him into the new avatar of Madkat from Swat Kats. As Madkat, he acts out his feelings, be it out of hilarity or vengeance. Regardless, he thinks it's all funny. The more Miro stays as Madkat, the less he can tell if his actions are the spirits or his own.

Madkat originally had an appearance identical to the original Madkat, being a large and muscular with orange and yellow skin divided by color in such a way that it resembled a Jester's outfit and a jester's hat. Overtime, his appearance began to change. Madkat Miro now retains Miro's more compact height and build with yellow and blue skin. He occasionally is depicted in various palette swaps. His powers include magic, minor reality alteration, hypnosis, elasticity, acrobatics, suppressively loud laughter, and the ability to create and remotely manipulate Marionet Puppets. He is often depicted using large hammers, yarn balls, playing cards, toys, and copious amounts of liquid latex.
