Demons of The Lesser Key of Solomon

The first one pictured here would make for a fun enemy.  Jumping over it would be a bad idea, and it could cling to the ceiling and attack with the tongue/tentacle, or even use that to swing around.  

It may be entirely possible that not all of these demons will be enemies. Zagan from the Ars Goetia apparently has the power to "make men witty; he can also turn wine into water, water into wine, and blood into wine (according to Pseudomonarchia Daemonum blood into oil, oil into blood, and a fool into a wise man). Other of his powers is that of turning metals into coins that are made with that metal (i.e., gold into a gold coin, copper into a copper coin, etc.)."
I personally would like to see more unique characterizations of these demons than simple villains and monsters for you to vanquish. Here is a  A list of 90 Demonic sigils in which you can see that not all are exemplified by their evil nature. 

I would enjoy that highly! As a die-hard fan of Aria of Sorrow for the Gameboy Advanced I loved being able to summon those "Support" demons to repeatedly pummel my foes.

Man, those seals are really cool

It's fine.  Plenty of spirits appear in multiple texts with variations on names, seals, offices, etc.  That list is way, way, waaaaaaay off, though.  Like, off to the point where people either didn't do any research, or they just took the Berbiguier route and made stuff up.

A few examples:
"Adnachiel, The Hunter Demon" isn't a demon at all, it's an angel.
"Agiel, Lord of Calamity" is also an angel.  You use its name as part of the 1st pentacle of Mercury to invoke spirits.
"Ambriel, The Changer" is an angel.  It's a prince of the order of thrones, and its name is used on charms to ward off evil.
"Aratron, Demon of Sorrow" is an Olympian spirit known for alchemy, medicine, invisibility, and the ability to make barren women fertile again.  You could arguably cause sorrows, especially when alchemy is concerned, but it's a far more benign spirit than, say, Draplos, an evil-natured deceiver. 

And so on, and so on...

Some demons are portrayed as cunning, and some more as forces of nature limited to act only within their spheres, and approached only with divine protection or with tasks/requests/offerings that fall within those spheres.  Ditto for some angels, as many are cut from the same cloth, at least according to lore.  The lore, though, is long, rambling, often inconsistent, riddled with errors at times, and also, most importantly... fiction 

I'd love to see some demon NPCs as well.  It's one of the reasons I enjoyed the Shin Megami Tensei games so much.

Yeah, there's several different spellings or even alternate names for most of these demons. It's not exactly what you would call an exact science. 

Yea I realized this with Astaroth. My girlfriend is suddenly interested in the game since they are using demons of The Lesser Key of Solomon which she knows about. 

I'm sure she'll quite enjoy this game then! Should be fun playing co-op with her as she can probably name all of the demons used

i like that pic of me much better than the one of the guy humping the rat, stupid artistic license >P

but when you look at many of the 'demons' in those books, they draw a lot from the pagan religions before that, often twisting them to whatever end the author wants, was much more fun to be loved than feared >_>
