Do We Have This One? Needs A Better Title

Basically, a character who is Satan in everything but name. He runs a place where the dead go, or is the ultimate evil in whatever work he's in, or just loves torturing people, but he's not Satan. This trope has two forms:

Type I: The work is meant for kids, so they can't come right out and say it. The implications are obvious. Type II: The work takes place in an alternate world where a made up character has Satan's shtick.

Examples:

• Him on The Powerpuff Girls
• Lucius Heinous VII on Jimmy Two-Shoes
• The Red Guy on Cow And Chicken
• Chernabog on Fantasia. Overlaps with Everyone Hates Hades, but Walt Disney meant for it to be Satan, and it was changed by marketing.
• Trigon the Terrible on Teen Titans
• Mephisto in the Marvel Universe.
• Mr. Boss on The Baskervilles
• Senor Diablo on Johnny The Homicidal Maniac
