Ferb Fletcher (2nd Dimension)

Ferb Fletcher is a boy in the Flynn-Fletcher family, the step-brother to Phineas and Candace, and the 2nd Dimension counterpart of Ferb Fletcher. Stuck in an area which is ruled by Heinz Doofenshmirtz, he has grown up without summer vacation and has never heard of it.

Website Info
''A boy of few words, Ferb likes to keep to himself and out of trouble. He doesn't leave the house much due to the patrolling Norm bots and his mother's instruction that talking to neighbors is dangerous.''
