Sigh, and I'd hoped the recent "I am a new super-evil villain called Zodiac, and to prove I'm a real super-evil badass, rather than doing something creative and new, I'm going to casually mention I've killed all the other people who were members of the more interesting and novel Zodiac offpanel" was an isolated throwback to the 1990's
And add me to the "Stop fucking gratuitously killing JLA/I members Robinson!" group.
