Probably Dead?
Ah Alright!Hey! I was catching up on the conversation and I just want to set the record straight - there are no movesets and there are no levels.
All I ask is that you are realistic. For example, Mew is a pretty powerful Pokemon but with having Jade, a novice as a trainer as well as only knowing Mew for roughly a year, they won't battle very well at first. I like to think that in order to be successful, the bond between Pokemon and trainer has to be developed and fortified.
Scarlett might have an easier time because she's known Entei and has battled Pokemon for 11 years. However, she might still have a bit of difficulty since Entei was essentially her parent and she didn't battle with him much. They have a father, daughter power dynamic which can be an issue when they start battling since the trainer is supposed to be the master and the Pokemon is supposed to be the battle companion.
As far as what your legendary is capable of, I would do research on that Pokemon, see what their Pokedex entry looks like and figure out for yourself what you think your Pokemon is capable of and if you're not sure about something, I'm more than happy to help. Just PM me your question.
