...Well I mean Entei are not even unique pokemon. There's a bunch of them. They're also just the offspring of a god-like pokemon, ho-oh. Kind of like every non-legendary is the offspring of mew.
Entei is a relatively anger prone pokemon that respects the skill it took to capture him in the first place. That being said, yes. He is Julia's dog and does what she says, though he is indignant to being ridden by her. Keeping in mind that Julia respects him and his power, partially out of fear. He is prideful, and there's no telling what his pride and or temper might do to change his obedience when either is violated.
Entei is easily the most independent of Julia's pokemon, and is also fully aware of why she came to the tournament, which cant' be said for all of them.
It's alright, really. I try not to hold grudges especially over mistakes. Hostility towards other RPers makes RPing less fun and can even ruin it.
Lumine is Julia's Abomasnow, the only one of her pokemon that has not been let out of it's ball in the RP so far.
Let me point this out. She weighed which was more dangerous to send out--Lumine or Entei...and she chose to end out Entei. Food for thought.
And eh... I suppose I could let one of her pokemon out if you wanted. Just one though. Having a bunch out would murder my muse.
...Thanks for letting me know Grieger posted. Also, that sounds about right.
