The first thing you should do when taking care of Thundurus is nurse him back to peak physical health. I would advise having a Nurse Joy perform a house call in order to get the best advice for this situation.
Then, when Thundurus has recovered enough to fly and hold his own in battle, release him back into the wild—honestly why are so many of you intent on seeing the catastrophic destruction of our world?!
