- Klarion activates some monsters while chasing Secret and Deadboy. Meanwhile, all the other kid heroes have regrouped with Old Justice and some of the adult-transformed teens. Simultaneously, the Superboys and the Wonder Girls are being experimented on by Contessa and her cohorts in the Agenda. Realizing they’re being used, the Point Men help the Superboys and Wonder Girls escape. Klarion then battles a grown up version of himself, a clone grown by Contessa. After being reunited with Teekl, Klarion and Doiby combine their magic and science and return everyone to their proper age.
