Real names: N/A
Gimmicks: Incredible wealth, love of supervillain cliches

3. Monkey Fist
Real Name: Lord Monty Fisk

2. Dr Drakken
Real Name: Drew Lipsky
Gimmicks: Mad scientist, quest for world domination
By far the most frequently featured villain on the series, Dr Drakken seems to have a new plan to take over the world every week… but he is always foiled by Kim. He’s a bit inept, then, but you can’t fault his ambition. Futurama fans might be interested to know that Drakken is voiced by Bender himself John DiMaggio.
Real Name: N/A
Gimmicks: Green energy generation, excellent fighter
Drakken might claim to be Kim’s arch-nemesis but it is really his sidekick Shego who is the teen spy’s most dangerous foe. Unlike her boss, Shego is actually competent and she can easily match Kim in a fight – check out A Sitch In Time to see what Shego can do at her worst. The character’s sharp tongue and badass attitude have made her a firm fan favourite.
