Shayne J'onzz (Sixth Dimension)

Shayne J'onzz is the son of the Sixth Dimension versions of J'onn J'onzz and Kendra Saunders.

When the Justice League first come to the Sixth Dimension, they are greeted by the believed future Justice League along with Shayne. While watching the deception of the World Forger, Shayne is reminded of the many different versions of the Justice League that have all gone through the same lies. He then decides to confront to the Prime Earth versions of his parents and shows them the truth about everything. After the arrival and reveal of the World Forger, he is sent to future Apokolips to be jailed with the Justice League. After helping them escape, he fights alongside the Justice League to defeat Alpheus and put an end to it all.

After their victory in the Sixth Dimension, everyone traveled back to the Prime Earth where they befriended Alpheus and made a promise to defeat Perpetua.
