How is your campaign? High level technology (as in Eberron)? If so, you could try creating some monsters that look like huge mechas (or take the Warforged Titan's stats) and call them Weapons (as in Emerald Weapon, Ruby Weapon, Ultima Weapon...),
Other ideas:
-pick a red dragon, boost its HD to heavens, turn it black and call it Bahamut, and when he uses its breath weapon, call it Mega Flare...
-use FF style magic (pick Radiant Assault (SpC), make it look like a huge light blast instead and call it Ultima or Holy, Spell Turning to Reflect, Mage Armor to Protect, Finger of Death to Death, use Baleful Polymorph to transform to frog and call it Frog, tweak Meteor Swarm to be a single sphere of fire and call it Meteor, and so on...)
I'm dried out of ideas.... will post more here soon...
EDIT: added more ideas for spells...
