A well-ballanced keyblade that provides an extra boost to your stats"
Ends of the earth that is found in Kingdom Hearts II Final Mix & Kingdom Hearts Birth by Sleep. Like Terra's other keyblades, it is able to shift into multiple forms, inlcuding a whip, a jet-vehicle, a spinning-cog weapon, a cannon, & a gigantic keyblade.
In Kingdom Hearts Birth by Sleep, Terra's Keyblade develops this form after he chooses Riku to Inherit the Keyblade. Then it takes this form permanently after his body is stolen by Master Xehanort, & his armor becomes the Lingering Sentiment. The Lingering Sentiment continues to wield this Keyblade, even when it attacks Sora, thinking he's Master Xehanort in Kingdom Hearts II Final Mix.
