I made the obligatory circus-themed villain group once, and this is an updated take on their main man, called — what else? — Ringleader.
That you know Ring Leader. You, sir, are not just an Artist, but a Collector, a Recorder, and a Maestro. Very nice touch with the bowtie. Which, truth be told, is flair. Doesn’t quite fit with the cape. But that laughing expression, the gloves, the wand, the hat… magnique! Ring Leader, a challenging foe for Green Lantern, Batman and Superman.
