Just like his original counterpart, he was voiced by Mick Wingert.
He appeared in the episode "Bad Po". When Po discovers the Mystical Mirror of Yin and Yang, the item splits Po into two halves. One being Good Po, who has Po's innocent nature and stupidity. The other being Bad Po, who is an arrogant brute: all the qualities of Po's alias as the Dragon Warrior.
Bad Po commits numerous wrong-doings in the Valley of Peace, such as insulting his friends, customers at Ping's Noodle Shop, and creating hatred and fear for the civilians. These crimes were blamed on Good Po. When the two halves soon meet, Bad Po manipulates Good Po and then imprisons him. Master Shifu finds out, but is imprisoned as well. When Shifu and Good Po escape, they form a plan with the Furious Five to restore Po to his normal self with the mirror. However, they had to do so before sunset, when the effect becomes permanent, as Bad Po attempts to take over the Valley of Peace with the help of Fung and the Croc Bandits. Bad Po fights the Furious Five, and Good Po helps by hurting himself, as the pain also affects Bad Po. Bad Po soon breaks the mirror and believes he has won. However, Good Po revealed to him that he had broken a copy of the mirror, and uses the true mirror to defeat the fiend, thus restoring Po to his normal self.
