Please refer to the "A Note About Hatch Meet - Ups"
Not saying that I have one, but they aren't so rare. All you get is one Epic Talent which I think is May Cast Empowerment or Fortify or Conviction
That's only with a first generation one. You never know what you will get when you hatch. Someone can breed in all kinds of cool traits into a scorpion. Just depends on which one you find to hatch with.
Just as with every other aspect of Wiz101 (and every other game) there are casual pet hatchers and hard-core pet hatchers. For a casual pet hatcher, the talents aren't nearly as important as having a special-looking pet to tag along with you on your adventures through the Spiral.
For end-game achiever types, a pet who supports their playstyle is far more important than the type of the pet. For everyone else, that's much less true. The original poster sounds like a casual player who just wants a scorpion as a pet and doesn't care much about whether scorpions have any "good" talents or even if it has any first-generation talents at all.
