I'll skip the drooling.
HP: 100. Strong for a Stage One. It will be around for a while.
Night Cry: Great for a Rocket deck. In any format. So its use is linear.
Toxic Claws: Great cheap effect, but a might costly with three energies but with the Night Cry power, it's a benchwarmer until ready to use.
Energy cost: Fits anywhere, which is the point.
Retreat Cost: One, a surprise as Persian are known for speed but one is low enough.
Overall: A perfect benchwarmer for a Rocket deck, and given Rocket's Meowth's usefulness, it is a quite viable card to insert in a deck by itself, complete with the sneaky Toxic Claws. But the lowish HP can be draining in time. 7/10.
