How does Sonic Adventure 2 Battle end?

Answer 1

It ends like this: Sonic and Shadow bravely obtain the power of the Chaos Emeralds and turn Super to defeat the Ultimate Life Form before it crashes the ARK on the planet!

Super Sonic and Shadow stop the ARK by using Chaos Control, afterwards you see Shadow continuing to fall his last words are spoken. It then shows Sonic back on the ARK delivering the bad news to everyone. He gives Rouge one of Shadow's rings he held, Rouge asks Sonic if Shadow was created to destroy us, Sonic answered "He was what he was, a brave and heroic hedgehog that gave his life to save this planet, Shadow the Hedgehog." Rouge assumes he's right.

Tails and Eggman are then shown talking. Eggman talks first and says he used to look up to his grandfather but he realized he meant pure destruction to the world. Tails said he wasn't sure if that's true but what he did know is that they all saved the world together, Eggman assumes he's right.

Knuckles and Rouge are now shown talking Knuckles asks whats next for Rouge and if it involves more jewel stealing. She answers she's done with that and she has more important things on her mind Knuckles just says if you say so.

Sonic once again is shown thinking out loud wondering if Shadow really was the Ultimate Life Form Amy interrupts and wonders whats wrong. Sonic says its nothing and then says, "Lets go back to the planet that's as cool and blue as me!" They all leave Sonics last words before he left were "Sayonara Shadow the Hedgehog" and then the credits!
