A Hamato Clan ancestor (credited as Mystic Aura) appeared in Rise of the Teenage Mutant Ninja Turtles. In "End Game", Splinter consulted his scrolls on his next step of action. His dilemma was whether to give his teapot (which was actually the final piece of the Kuroi Yōroi) to Baron Draxum and save his captured sons in exchange for dooming humanity, or to not give up the final piece and keep humanity safe at the cost of losing the Turtles. His ancestor urged that his destiny was for the latter to take place. Splinter realized how unacceptable it was to give up his sons and shredded the scrolls in anger. He then chose a third option - to go and save the Turtles himself.
Trivia
- The Hamato Clan ancestor is voiced by Hoon Lee, who was the voice of Hamato Yoshi/Splinter himself in the previous animated series.
