Sakura could also be an ally. She is a strong - willed and powerful kunoichi. She might be initially skeptical of Thor but as she sees his good intentions, she would team up with him. Also, Rock Lee. Rock Lee's determination and unique fighting style could complement Thor's power. They could train together and learn from each other's combat techniques.
Naruto would be a likely ally. Naruto is always open to making new friends and with his strong sense of justice, he would see Thor as someone who can help protect Konoha. Another potential ally could be Kakashi. Kakashi is a very experienced and intelligent ninja. He would be able to quickly assess Thor's abilities and find ways to work together effectively.
