My absolute top dynamic is Bane and Jules. They are complete opposites but work together so well. Bane is more of the brute, and Jules is a softie. They met in the rain after Bane fled from hell (Cerberus was a bad father). Bane was weary of Jules but trusted him after a while. They may have different solutions, but when they find one that sticks, they work in harmony. They are in the middle while they can be sweet and loving, sometimes they have small arguments. My favorite moments when Bane says something sarcastic or jokingly in serious meetings and Jules scolds him. Jules rarely fights, so Bane protects him in dire situations.
Both have a common understanding of powers. Bane has a mix of canine and demon abilities while Jules can use basic magic and white magic. Both also use their weapons, even though Jules doesn't fight often. Bane uses an umbra sword, a sword whose blade is forged of shadow. Jules uses a staff made of his white magic.
They have many badass and heartfelt scenes and have a bond that holds them together. At the end of the story, they are in a relationship.
