Circadia Senius

Circadia Senius is a supporting figure in the far-future 30th-century setting of the Legion of Super-Heroes, inhabiting the same world as characters like Brainiac 5 and Rond Vidar.

Introduced to DC readers in 1986's Who's Who: The Definitive Directory of the DC Universe — that beloved Copper Age institution dedicated to cataloguing the far corners of the DC cosmos — Circadia Senius is a figure rooted in the far-future world of the Legion of Super-Heroes. Created by Len Wein, this character inhabits the same rarefied corners of the 30th century as luminaries like Brainiac 5, Rokk Krinn, and Rond Vidar, lending an air of legitimacy to even a handful of appearances. Rare in the catalog but genuinely part of DC's Legion tapestry across titles like Legion of Super-Heroes, Adventure Comics, and Legionnaires Three, Circadia Senius is exactly the kind of deep-cut discovery that rewards the dedicated fan who loves exploring every nook of comics' most expansive shared universe.
