Batman Beyond #28 Variant Edition

"The Joker prepares to deliver his fatal punchline: everything and the kitchen sink hits the fan for Batman and Robin, and even with Dick Grayson's help, the Dynamic Duo of tomorrow and Bruce Wayne may not stand a chance. Will Joker turn Terry's brother into the new Jason Todd? Is now a good time for Terry and Bruce to clash? And why are Neo-Gothamites cheering on the Clown Prince? Will anyone survive 'The Final Joke'?"
