Master Shen Character Facts

Master Shen is the master of the Crane School and Mercenary Tao's older brother. Whilst they both trained at the Mutaito Training Academy, a rivalry quickly grew between Shen and Roshi. Master Shen and Mercenary Tao, likewise, began to fight over the smallest things. Eventually, a simple spilled bowl of rice was enough to break the brothers apart. 
Shen and Roshi were both students of Master Mutaito, and they quickly became rivals. Master Roshi states that when King Piccolo defeated Mutaito, he could not deal with the shame of losing in front of his pupils. Roshi believes that on that day, Shen changed for the worse. Mutaito returned and sealed King Piccolo with the Evil Containment Wave, but died in the process. Shen was never the same again. His heart became dark, and his Master's failure and eventual death weighed heavily on his mind. He eventually started the Crane School, whilst Roshi started the Turtle School, and their rivalry continued.
