An effective way to match your villain to your hero is to create an asymmetrical relationship between their strengths and weaknesses.
When strengths and weaknesses are not matched, the relationship between the characters becomes interesting. The opportunity for conflict increases. Even when strengths may be nearly equal, the field of battle switches to weaknesses. Spiderman and the Green Goblin are roughly equal in strength. So, where's the chink in Spidey's armor? Mary Jane. What's GG's weakness? He's insane.
