I have noted several similarities between Spider Man & Scarecrow from DC's Batman. I will proceed to state several of them.
- They both have brown hair.
- They both wore glasses at some point in their lives.
- They were both picked on for being nerdy.
- They were both caucasian.
- They both took there anger out on their enemies. (Spidey dealt with Flash Thompson in "The Terrible Threat of the Living Brain" and Jonathon Crane alias Scarecrow dealt with his enemies by becoming a psychologist.)
- They both became costumed characters. (Peter Parker became Spider Man & Jonathon Crane became Scarecrow.)
