Concept artist Andy Poon has continued to roll out several of his designs for the current wave of DC Comics-based TV series -- with his latest batch featuring crime-fighters Vigilante and Citizen Steel, as they appear on "Arrow" and "Legends of Tomorrow," respectively.

Both introduced in the 2016-2017 television season, Vigilante and Citizen Steel are new additions to the DC TV universe, as the shared world continues to expand and crossover, as exemplified in the recent four-part "Invasion!" crossover.

Take a look at the slightly varied designs for Vigilante and Citizen Steel below:

Starring Stephen Amell as the Emerald Archer, "Arrow" airs Wednesdays at 8 pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, John Barrowman, Willa Holland and more.

Airing Thursdays at 8 pm ET/PT on The CW, "DC's Legends of Tomorrow" stars Arthur Darvill as Rip Hunter, Brandon Routh as the Atom, Victor Garber and Franz Drameh as Firestorm, Caity Lotz as White Canary, Maisie Richardson-Seller as Vixen, Dominic Purcell as Heatwave and Nick Zano as Citizen Steel.
