The Johnny Stopping Evil Force 5 is comprised of 5 of Johnny Test's worst enemies. Over time, the Beekeeper was replaced by Zizrar (the mole king), but other than this the group has remained unchanged. The members of the group are Wacko (founder), Brain Freezer, Mr. Mittens, his butler Albert, Beekepper (resigned) and Zizrar (who replaced the Beekeeper). Now that Brain Freezer has become good and Wacko is estranged from the group, however, it is unknown if they still exist or if they have disbanded.
Over time, Johnny Test has faced a number of evildoers, always defeating them in the end. From cats, to clowns, even a bee loving old man, Johnny Test made himself several enemies. When Wacko paid the price to get 4 of the villains out of jail, they were then introduced to Wacko's brilliant alliance plan eager for revenge against the flame headed boy, and they willingly signed up with him, exchanging their traditional outfits in for similar outfits with a cross over the chest.

- Mr. Mittens As Tim discribed, Mr. Mittens was never a friendly cat, he despised his owner for never cleaning his litter box and all the dogs for chasing him.

However, the zapper wasn't strong enough to turn humans into cats, so he invaded the military base and charged his zapper with their million-volts electricity source.
