Brainy-Yak

Brainy-Yak, real name Brian Yak is a villain from Robotboy. He was once a normal yak, but he was mocked by some of his fellow yaks and a young Dr. Kamikazi for how stupid he was Professor Moshimo (who at the time was just a yak herder) hated the treatment he got, so he made him smarter by giving him a brain transplant, which he learned from comic books. He gave him a big brain, but this lead to him not being able to relate to the other yaks, which made him think he was a freak. He blamed Moshimo for giving him the brain transplant, which made him hate him and run off.
