Their relationship could develop in a very mentor - mentee way. T'Challa would be the strict but fair mentor, teaching Peter about combat strategies, technology, and how to handle difficult situations. Peter would be the eager student, always asking questions and coming up with new ideas. As they spend more time together, they would become like family, with Peter looking up to T'Challa as a father figure and T'Challa being proud of Peter's growth as a hero.
At first, their relationship might be a bit rocky. Peter is used to his own ways in New York, and T'Challa has his strict Wakandan values. But as time passes, they start to understand each other. T'Challa would see Peter's determination and courage, and Peter would see T'Challa's wisdom and leadership. They would bond over their shared goal of protecting the innocent.
Initially, Peter might be in awe of T'Challa and his Wakandan heritage. T'Challa would be cautious but intrigued by Peter's abilities. As they start to interact more, T'Challa would open up about his own past and struggles, which would make Peter feel closer to him. Peter would also share his experiences as Spider - Man, and they would find common ground in their sense of justice. Over time, their relationship would be a strong one, with mutual respect and love, and they would be a great team in facing any challenges that come their way.
