   Summary

   Ben Tennyson — yeah, the world-famous hero — is now 25. Still the same playful, kinda selfish guy, and yep... still single. Girls totally adore him and would fight over him, but Ben? He’s all about that wild, everyday life he’s used to.

   Things were chill until he realized his longtime partner Rook couldn’t keep up with him in battle anymore. Just like that, Ben was flying solo again.

   On their last mission together, they went after someone people were calling “Teen Ben 10.” But when Ben tracked the guy down, he came face-to-face with Kaiden.

   Turns out... Kaiden is Ben Tennyson’s youngest kid — and he’s part Necrofriggian.
