Comic legend Mike Grell has covered a wide range of the DC Universe during his remarkable career, from his early run on Superboy and the Legion of Super-Heroes to his long tenure as the ongoing writer of Green Arrow, and most famously as the creator of The Warlord.

What’s next up on his plate for DC? Drawing a sequence telling Iron Maiden’s backstory starting in issue 7 of T.H.U.N.D.E.R. Agents!

T.H.U.N.D.E.R. editor Wil Moss explains Mike Grell’s contribution to the series:

We’re thrilled to have an artist as legendary and as talented as Mike Grell on board to help us kick off the second arc of T.H.U.N.D.E.R. AGENTS with May’s #7, joining writer Nick Spencer and the regular art team of CAFU & Bit. Mike will be drawing a sequence starting in #7 that dives into the backstory of the classic TA foe The Iron Maiden, revealing the crucial role she played in the current team’s formation. Also starting in #7 is a sequence set even further in the past by the über-talented Nick Dragotta, channeling his inner Wally Wood. The secrets revealed in these two timelines will have shocking -- that’s right, shocking! -- consequences for the team in the present. So don’t miss it!
