The Source Wall has degraded too much, and the League must patch the hole right now or the whole Multiverse will collapse!

Whoops… but never fear! Kyle Rayner, Miss Martian and Steel — from the non-planet-eating Titans team — guest-star with a plan to create a new Entropy Titan… one that’s so crazy it just might work.
