10 Obscure Batman Facts That You Have Probably Never Heard Of
5. He Adopted A Piece Of Starro As His Son
You know, the giant alien starfish that controls people via telepathy and conquers entire worlds, yeah, Batman kept a sentient piece of them as his adopted son.
During the No Justice storyline, Starro joins the Justice League in their battle against the Omega Titans. Determined to redeem themselves after all their horrible past deeds, Starro sacrifices themselves in order to help the heroes win.
In the aftermath, Batman comes across a surviving piece of their fallen ally, and decides to keep them. This sentient miniature Starro is housed in the Hall of Justice. In uncharacteristically lazy fashion, Bruce simply names them Jarro, after the fact that they used to live in a jar.
Jarro becomes strongly attached to Bruce, coming to regard him as their father. They also become an important ally to the League in their battles against the likes of the Legion of Doom. Despite their background, Jarro is shown to be quite affectionate and protective of others, at one point going as far as manipulating the League to stay away from the Legion, so they don’t get hurt.
