So, I've been kicking the idea around in my head for ages, and I just can't figure it out; What is the perfect Evil Overlord build? I mean, look at what a good and proper Evil Overlord needs: Minions, presence, brilliance, charisma, and power. One needs to be a brilliant strategic planner, and needs to be a credible threat. Either large hamminess or extreme genre savvy is needed. Examples of perfect Evil Overlords are Anubis, minus the omnicidal tendencies and near-omnipotence, Ba'al, Lex Luthor, and David Xanatos are all perfect examples. Now, full casters obviously make the best choice, with Charm/Dominate, summons and Planar Bindings, necromancy, and divination, and artificers are tempting, as they have most of the same tricks, and easier access to golems, but really, I'm having troublel coming up with one that would be memorable, unique, unconventional enough the players won't recognize the entire build on sight, and incredibly dangerous. Dangerous enough to threaten an entire party of similar levels, from levels 10-ish to 20-ish, and with nothing the players aren't allowed(No gestalt, special anything, and preferably, though not necessarily, no flaws, and restricted to WBL for personal equipment(Though not in his dungeons)).
I guess the real problem here is that the players are all relatively clever, and will spot a build typical build a mile away. The biggest, most important part of an evil overlord is memorability. Typical God-Wizard is incredibly dangerous, yes, but is no more than the last god-wizard they've seen with some extra levels and more resources. I mean, Anubis was scarier than Kronus, despite being basically the same guy with a bit more baby-eating and hamminess(Which was really quite a feat, given the Goa'uld being, well, Goa'uld), but the difference in technique was part of what made him more interesting. And, really, I need this thing to be dangerous. Dangerous to things like CoDZillas and Batmen.
So, I'm stuck. The best things I've been able to come up with are standard wizard builds, a couple of Ur-Priests, a crappy Dread Necro, a Thrallherd, and a commoner. All of these are mundane, boring, and easily recognizable by anyone with reasonable systems mastery, although Duskpriests are pretty cool.
So, can anyone help me out? I really got nothing. Also, sorry for the disorganization. It's 2AM, and I'm tired.
