What was last words in sonic adventures 2?

There are no definitive "last words" in Sonic Adventure 2, as the game has multiple endings depending on the player's actions and the character they're playing as.

Here are some potential candidates for "last words" depending on the ending:

* Hero Story: After Sonic defeats Shadow and saves the world, he says "See ya later!" to Tails.

* Dark Story: Shadow, after destroying the ARK and seemingly killing everyone, says "This is my world now..."

* Ending Cutscene: After the credits, Knuckles says "I'm gonna find that Chaos Emerald..."

Ultimately, it's up to you to decide which line, if any, you consider to be the "last words" of Sonic Adventure 2.
