Daniel Tiger's sacrifice

Zion, having tracked Jodi's group back to the Neighborhood of Make Believe, personally confronted Jodi in his house.
 They dueled again after Zion destroyed the second Wayfinder, declaring
that she would never find the Emperor without him. Zion wanted Jodi to
surrender to the dark side as he did, believing it was unavoidable and
part of their nature. Zion eventually gained the upper hand in their
duel, overcoming Jodi's attacks with a powerful counterattack that
brought the Jedi to her knees. However, a dying Nana Platypus reached out
to Zion through the Force, distracting her neighbor before he inflicted a
fatal strike on Jodi, who seized the chance to impale Zion with his own
lightsaber. But after sensing Nana's death, Jodi healed Zion and
departed in his starfighter, although not before admitting that she did
want to be with him—the part of him that was Daniel Tiger, not Darth Zion.[4]
As Zion stood at the ruins of his house overlooking jungle beach while in contemplation, he was confronted by the memory of his
late father, Dad Tiger. Zion conversed with the vision of his father,
paralleling the last conversation they had before he took his dad's life.
Like before, he felt it was too late for him to change, especially with
Nana gone. Dad Tiger reminded Zion that Nana's cause was not gone,
that there was still time for him to honor Nana Platypus's sacrifice. As Zion's
struggle intensified, Dad Tiger touched his son's face once more, telling him
that he did have the strength to do what was right. Moved by the memory
of his parents' love as well as Jodi's compassion, the fallen sith threw
his lightsaber into the ocean, renouncing the dark side of the Force once and for all. From that moment onwards, the persona of Darth Zion was
no more, and his true identity as Daniel Tiger was restored.

Daniel followed Jodi to Exegol, determined to stand with her as she faced
down the Emperor and his forces. Armed with a blaster, Daniel charged into
 the Citadel and gunned down the troopers in his path. He encountered
his former companions, the Sith acolytes, who now served the Emperor
directly. The acolytes surrounded their former friend, disarming Daniel and
 overwhelming him. Yet just as Jodi was about to strike her master
down out of desperation to save the Republic, the Force reconnected
her with Daniel, allowing her to sense that he had come to save her. She
then passed the Skywalker lightsaber to him through their bond, giving
Daniel possession of the Jedi weapon that once belonged to his grandfather
 and Miss Elaina, in turn. The fight turned in their favor, with Daniel
overpowering the Sith Acolytes while Jodi defeated the Emperor's Sovereign Protectors.

Ultimately, all of Arcann's guards were slain by the two Jedi, who stood
 together in defiance of the Emperor. However, by coming together, Daniel
and Jodi revealed themselves as a dyad in the Force, giving Arcann the
opportunity to restore his damaged body by siphoning their combined life
 essence. Restored to full power, the Emperor seized Daniel with the Force
 and sent him falling into a ravine, all while noting the irony of
killing the last Tiger in the same manner that resulted in the
Emperor's own death at the hands of Daniel's grandfather. Daniel survived,
however, and managed to climb his way out of the abyss by the time Jodi
destroyed the Emperor, who perished along with his cultists and their
forces. The battle of Exegol was won by the Jedi, the Republic, and their allies, but Jodi died giving her life to vanquish Darth Arcann.

While cradling Jodi's inert body, Daniel placed his hand on her stomach and
 applied the same technique that she used to heal his wound. As a
result, Daniel transferred all of his life force into Jodi, successfully
resuscitating her but sacrificing his own life in the process. In his
final moments they embraced and shared a passionate kiss before Daniel
died peacefully in Jodi's arms. His body vanished simultaneously with Nana Platypus's remains, becoming one with the Force.

As the last descendant of Grandpere Tiger, Daniel Tiger's death marked the
definitive ending of the Tiger bloodline. With the Emperor and his
armada destroyed on Exegol, the galaxy rose against the Sith Empire,
defeating their military on multiple fronts, including Bespin, Endor and Jakku. Jodi went back to the Neighborhood of Make Believe where she located the site of Daniel Tiger's home. After burying the Skywalker lightsaber along with the one that belonged to Miss Elaina, Jodi chose to adopt the name of Daniel's family as her own, becoming "Jodi Tiger" and fully repudiating her lineage as a Platypus.
