Editing Splinter (Teenage Mutant Ninja Turtles) (section)

==2012 animated series==
In the [[Teenage Mutant Ninja Turtles (2012 TV series)|2012 series]], Splinter is again introduced as Hamato Yoshi, voiced by [[Hoon Lee]]. His relationship with Oroku Saki is mostly intact, with the Hamato and Foot Clans later revealed to have had a long-term conflict with each other. Despite being raised as brothers, both Yoshi and Saki become rivals due to their affection for Tang Shen, and Saki wishes to discredit Yoshi in front of her. Yoshi loses his temper by mistake and the altercation forever destroyed their relationship, culminating with Saki learning of his true heritage and starting a battle that burns down the Hamato Clan monastery, indirectly killing Shen and, seemingly, Shen and Yoshi's daughter, Miwa.

After moving to New York City, Yoshi has just purchased four pet turtles when he stumbles upon an exchange in an alley between two Kraang droids. Seeking to silence Yoshi before he can share what he has seen, a fight ensues and the canister the droids have been carrying smashes open, splashing both Yoshi and his turtles with a mutagen. As the result of stepping on the tail of a black rat upon entering an alley, Yoshi mutates while the Turtles take on human characteristics. Realizing he can no longer live a normal life, he retreats to the New York sewers where he raises his pets as sons and teaches them ninjutsu. Compared to his earlier counterparts, he is very strict in this series.

Splinter's sons, along with their new friend April O'Neil, soon become involved in the conflict with both of Splinter's old enemies, the Shredder and the Kraang. Reluctantly allowing the group to get involved, Splinter appoints Leonardo as their leader and continues to offer counsel and lessons as they engage various foes. Recognizing great sensitivity in April, he begins training her as a [[kunoichi]] and comes to regard her with a fatherly fondness. Splinter ventures from his lair on only two occasions. The first is when he falls under the control of the [[Rat King (Teenage Mutant Ninja Turtles)|Rat King]], who attempts to persuade him to forsake his humanity and embrace the life of a rat. Splinter eventually breaks free with the Turtles' help and defeats the Rat King. The second is when Shredder kidnaps April and lures Splinter to his stronghold for a final confrontation. Splinter overpowers Shredder's men and engages his old foe. Shredder reveals that Splinter's daughter, Miwa, had not died and that Shredder had taken her and raised her as his own. Splinter nearly defeats Shredder, only to be attacked by Miwa; Miwa, whose name is now Karai, has been taught, by Shredder, that Splinter is responsible for her mother's death.

As the second season progresses, Splinter tells the turtles about his true relationship with Karai. He is eventually able to convince Karai of the truth about their past, but she subsequently mutates into a snake-like being when Shredder's plan for revenge backfires. Later, Earth is invaded by the Kraang and, in the ensuing battle, much of Splinter's lair is destroyed before Splinter is able to defeat Kraang Sub-Prime. Splinter then leaves the lair to find his missing sons. Splinter again engages Shredder in battle and, seemingly victorious, Splinter prepares to reunite with his sons, April, and Casey Jones, only to be attacked from behind by Shredder and thrown into a sewer drain. He is rescued from drowning by Karai and left in an area of the sewer to recover.

At the end of the 3rd season, Splinter asks Shredder for a truce to stop the alien Triceratons. Shredder agrees but at the end of the battle, Shredder kills Splinter. The turtles hold him one last time before they, Casey and April flee with Fugitoid, as he arrives at the very last moment in a spaceship as Earth is sucked into a black hole.

When the turtles go through the time and fail to claim all the Black-Hole Generator pieces to help in the battle against the Triceratons and warn Splinter in time to stop Shredder from killing him. Splinter defeats Shredder, somewhat paralyzing him as Tiger Claw takes him away. When Shredder has himself infused with mutagen, he kidnaps Karai and demands her to come. Splinter fights Shredder along with the turtles, and the fight, leading up to rocky crevices and chasms below, Splinter and Shredder fall into a gaping chasm. Shredder's fall stops short as he lands on a rock outcrop as Splinter falls way down. He is still alive but his leg is broken. He sees the Rat King come toward him, seemingly surviving his fall down as well. Meanwhile, the turtles try to find him but Shredder goes after them. Splinter fights the Rat King but soon tumbles down and realizes that his fight with the Rat King was all a hallucination because of his fever he had developed in the chasm. He finds the skeletal remains of the Rat King and Donatello and Michelangelo find him, alive and well.

He later attempts to use his healing mantras to help April recover from the influence of the crystal fragment of the mystical Sol Star, and receives a vision of the ancient Aeons themselves but is overpowered by the form of a demonic Aeon. As April becomes possessed by the cosmic entity from within the Sol Star fragment, he attempts to reach her but is contained by April's exceptionally strong telekinesis. Regaining consciousness in the ransacked lair, he warns Donatello to be very careful as that being was not April. When April awakens from her ordeal, he expresses how impressed he is at how April was able to literally destroy her demons. He is once again killed by Shredder during a battle when Super Shredder impales him with his mutated claws and throws him off a rooftop. Splinter is buried at the O'Neil farmhouse. His spirit still gives his sons advice.

In season 5, Splinter's spirit briefly returns to the physical plane in order to help his family and friends after Shredder's henchmen accidentally open a portal to the nether world in an attempt to revive the Shredder and bring him back to life. After the crisis is stopped, Splinter has a final  goodbye with his family and friends, and his spirit peacefully floats into the sky and returns to the afterlife once more.
