The Black Panda 1(2019)

The series starts with the Black Panther/King of Rakanda (Osiris Blade) going to Wakamono, Japan, in search of the City of Youth and a rare substance called Peckeranium, which is said to extend life and give power. He finds the headquarters of the mysterious Black Panda (played by Alex Chu), who is defended by his two Panda brothers (Levy Foxx and Ken Ott). If he wants to trade his Vibranium for the Peckeranium, he needs to eat their cumloads and perform an ancient panda ritual that involves being buried in an avalanche of sperm while going under.
