How about Cthulhu for R'lyeh, tentacles, wings and all
. And maybe some more kinds of dragons. Here's some others;
Insect Lord : A nature/death mage that rides on a large beetle. Automatically summons swarms of Dragonflies in combat.
Undying Tyrant : C'tis pretender. A massive undead T-Rex with high death magic. Spreads diease in the province he's in.
Master Engineer : Ulm pretender. Earth/astral mage that fights in a titanic suit of clockwork armor. Great bonus added to sieges.
Dragon Lord : Combat pretender that rides a Wyvern. Can ritually summon Draconians to aid him.
Well that's all I can think of right now.
