From "Starfire"!

After the Homocider's destruction, the mysterious figure now plans to take matters into their own hands (as said in a previous pic, which you'd already know if you were payin' attention to the series so far), only this time, the identity of this anonymous villain will soon be revealed! I won't say much, but let's just say as soon as this vile being gets to Earth...an old rivalry will be revived.
