Dragon Ball Z Kai: Peace for the Future! The Spirit of Goku is Forever(2011)

Trunks returns to the future and is reunited with Bulma. As tranquility seems to return, the androids are attacking again. Trunks saves an elderly man from being killed by Androids #17 and #18. Thanks to his training in the Hyperbolic Time Chamber, Trunks easily destroys the two androids. Three years later, Trunks prepares to head back into the past to tell everyone of his victory. However, there is still one more android to stop: Cell, in his Imperfect Form. After a brief fight, Trunks launches Cell into the air and destroys him with ease as well. Peace is finally restored to the future timeline. Back in the present, Goku begins his new "life" in the Other World.
