Name: Unknown. There was actually a survey of sorts on this in the Powerpuff Magazine. the results:

Ed -- 16%

Tyler -- 11%

Cody -- 3%

Sir Sebastian "Puffy" Crumblebottom -- 4%

The Villain Formerly Known as the Prince of Darkness -- 64%
 
 

Location: unknown
 
 

Accomplices: none, if you don't count Mr. Quackers. Quackers is not exactly an accomplice -- more of an advisor. he doesn't actually seem to have anything to do with committing the crime, just planning it. In the bathtub.
 
 

Outfit: (the most fun part!) the essential santa claus (santa claws??) suit, plus thigh-high hooker boots and fuzzy pink fluff about the neck and waist.
 
 

Powers: anything! well, probably not, as he seems to be unable to beat the Powerpuff Girls... at least so far. He has a see-all, hear-all TV, and he seems to be able to possess what he sees/hears with his Magical Microphone. He can also make things (like Octi) bigger and more evil. Or is that included under "possess things"? Well, I clarified. He can fly and do the same laser-vision things as the powerpuff girls (and you thought they were special). He can get big and scary and frighten the living daylights out of anyone who comes near him. He can make piñatas come to life. He can shoot a laser-beam-thing out of his mouth, which looks a bit odd when he does it (in Meet the Beat-Alls) but worship-worthy nonetheless.
 

Agenda: to destroy the powerpuff girls. more specifically...
(warning. spoilers.)
Octi-Evil: he possesses Octi (Bubbles' cute stuffed octopus) and talks to Bubbles through it. Buttercup and Blossom are going at it over who's going to be the leader, and Him devilishly uses Bubbles to come between B-cup and Blossom. ("uh, buttercup? Octi says YOU should be leader.") Him makes Octi get really big and start destroying Townsville. Octi grabs Bubbles, and B-cup and Blossom are fighting too much to notice... but eventually they stop fighting and are friends again and Octi turns back into Him and he curls up in a little ball and disappears in a flame.

Tough Love: Townsville is happy and everyone loves the Powerpuff Girls. Except Him. Who plots in the bathtub with Mr. Quackers to kill the PpG by turning everyone's love for them into hate.  He accomplishes this by some really neat Macbeth-type magic, and makes all the Townsvillers destroy the powerpuff girls.  They don't want to hurt the ones they love, so they don't do anything, until b-cup realizes Him is behind it and starts throwing punches. So he's defeated again, except he'll be back... and never does repeat performances.

This episode is also the one with the Infamous Professor Lick. If anyone knows how to hook a computer up to a VCR/if i need anything special, i'll see if i can get a clip of The Lick. summer is very soon (yay!) and i'll have free time then. but you have to tell me how. vampyre009@yahoo.com.

Telephonies: the gangrene gang is being truant, and they're prank calling people. They call the mayor (Grubber is Ms. Bellum) and tell him that something's opening and they're butting the ribbon and he's supposed to be there. so they get into the office and have access to... the hotline. they call the PpG (as the mayor) and have them go check out mojo and fuzzy, the lesser villains. then it's Him's turn. when they fly into wherever Him lives, he's wearing short shorts (BvsH grins), leg warmers and a headband, and doing aerobics on the floor. he hasn't done anything evil (note: look how scared the PpG are of him? isn't that delicious!?) and goes on with his exercising ("this figure doesn't come easy, you know!") Him gets in touch with Mojo and Fuzzy (Mojo calls him "Sir". hahaha!). they compare notes, and Him calls the mayor's office to find out exactly what's going on. he gets Big Billy on the phone, who is not the most intelligent of people, and who tells Him what's going on. Him, mojo and fuzzy break into the mayor's office and beat up the gangrene gang, and look good while doing it. Him does, anyway. And the day is saved, thanks to... Mojo, Him, and Fuzzy??

Speed Demon (BvsH purrs): the PpG get into a race while going home from school and get thrown into the future. They see lots of people who are old/dead (Ms. Keane, the professor and Ms. Bellum are old, the mayor's dead), and then discover that Him has taken over the world without the Powerpuff Girls there. ("and while you were gone, the world went to HECK!!" Okay, that sounds kinda lame. But whatever.) Then he gets big and scary and lovely... purrr... and makes Blossom cry. ha! then the PpG wimp out and fly back to where they came from.

Moral Decay: he's sitting in the dentist's office. that's all. this ep makes me cry.

Meet the Beat-Alls: One night, Him and the lesser villains (mojo, fuzzy & princess) all decide to storm the PPG's house. (Him is in his big form, but not the scary big form, just a big version of his normal shape) They all do it at once... and squish the powerpuff girls. realizing that as a team they can defeat the PpG, they start working together, with many Beatles spoofs along the way. There are many other pages that have lots on that. I don't (although I will mention that there are characters that look a lot like the beatles from yellow sub.) Mojo then falls in love with Moko Yono, a girl monkey, and the band comes apart. Apparently, without Mojo, Him & the other 2 lessers don't have what it takes. This episode (and moral decay) insulted me, and i wasn't too crazy about the Him aspect, but there's more on that here.

I really can't think of any more to put here. I'd love to put sound clips and whatnot up here, but we get back to the whole "BvsH is clueless at that" thing. but if I missed anything, email me.
