This wizard could have unique magical abilities and training methods that are not known in the British wizarding world.

His self - identity could also shift as he starts to define himself more by his new skills and abilities gained from the training rather than just his past experiences.
In such a fanfiction, Harry could face many challenges during the intensive training. This would test his limits and make him more resilient. Maybe he'll learn some ancient or forgotten magic, which could change the way he approaches future battles. Also, his relationships with other characters might evolve as he becomes more of a force to be reckoned with through this training.
