Drawings Featuring Siblings - Best Buddy or Worst Enemy?

Siblings often grow up together in the same environment and can often either be a person's first foray into friendship or the star of their villain origin story. As deep as the familial bonds run, some siblings can often have wildly differing personalities while others seem to be carbon copies of each other. With your siblings around, you're never alone (despite sometimes wanting to be). 

When we're first introduced to Inuyasha and his half-brother Sesshomaru (from Inuyasha) the two mixed about as well as oil and water. 

Do any of the sibling bonds depicted below stir up any feelings for you?
