Two of the most powerful beings in the universe, Yoda and Goku, decided to get together and exchange some knowledge. 

Though Goku is arguably one of the most powerful beings in the universe, there was one person who could teach him something. So he traveled to a galaxy far far away to train with Master Yoda. 

Just like Luke Skywalker, Goku trained and trained, and trained. 

Yoda and Goku take flight to their next training location.

With pizza for motivation, Goku went Super Saiyan Blue with ease. 

Goku finally learned how to fully channel and focus his chi.

Even the strongest beings in the universe need to treat themselves after hard work. Cheers!
