My mander minion is Fred, my fire minion from spectral minion is Harvey the ice is Bill or Bob depending on my mood, and the fire is George. My pet hydra's name is Cleo and so my spell is named Cleo too. :D
My son is a fire wizard, and we call the Dragon spell "Pizza Dragon," because it looks like he's standing on a pizza (maybe we were just hungry when we noticed this :-) ). I call my Orthrus "Moondoggie," because of the animation. I named my cyclops minion Bob, and my Minotaur minion Max. Still working on Medusa...she definitely needs a nickname too.
Like everyone else, I call Power Nova "the cheeseball" or "flamin' hot cheeseball". Ra = Super Chicken Heckhound = Fluffy Forest Lord = Chewie Humongofrog = Barfy or Frogger Poison = Ooze Orthrus = Drippy-nosed puppy
I also call Ninja Pigs (the ones you fight, not the spell) "Self-propelled sausage rolls"
Life is Sprinkle. Death is Pat. Balance is Blue. Myth is Sam(for all minions.) Storm is Swirly. My fire doesn't have her's yet. I named my unicorn spell Sparkle. My storm shark is Sparky the Sharky. Forest Lord used to be Bigfoot until I got the pet. We call it by my pet's name now.
I call my Sorcerer's Mander Minion Rufus. Also, minions should increase in strength as you level up, they just become obsolete in some way eventually the way they are now. You should also be able to control what they do. Don't bad guys usually tell their minions what to do and where to go?
