I've tamed just about everything on the ark and breed, imprinted and mutated most of them...but I still have the same tek stego I tamed near the start of my adventures. Good old Whack who while not the toughest or fastest creature I own, he's proven to be the most loyal. I got ambushed by a carno outside my base and I whistled to attack while unloading everything into it. Not ONE of my big tames came....but Whack certainly did. He charged that carno and had it taken out in two swipes. He got a handful of mejos as a reward. And while other stegos have been breed to be alpha rex killers he's still in my barn amongst multi colored dinos and creatures out of fiction
