Slowly, but surely, Legends of Tomorrow is starting to assemble its Justice Society of America. After a snazzy new logo and a few early ties, Season 2 has added iZombie star Matthew MacCaull in a Steel-y new role for the series, one with familial ties to one of our new series regulars.

It was Nick Zano’s arrival as Dr. Nate Heywood, a historian whose grandfather was Commander Steel, that initially tipped us off his Justice Society of America ancestor might be dropping by, and now we know for sure. Per Entertainment Weekly, MacCaull will join the team comprised of Obsidian, Stargirl, Doctor Mid-Nite, Vixen and Hourman, though most other details remain under wraps.

Elsewhere of Legends of Tomorrow Season 2, we know Nick Zano will play the Steel-y Dr. Nate Heywood, along with Maisie Richardson-Sellers as Vixen, two of several new heroic characters added to replace Ciara Renee and Falk Hentschel’s Kendra and Carter Hall. Patrick J. Adams will also likely appear as Hourman, following his arrival in the first Legends of Tomorrow finale, while Arrow star Stephen Amell will pop up in the October 13 premiere as Mayor Queen.

This year will also see the Legends team going up against a Legion of Doom of sorts, comprised of Malcolm Merlyn (John Barrowman), Captain Cold (Leonard Snart), Damien Darhk (Neal McDonough) and Reverse-Flash (Matt Letscher).

We’ll surely hear more of Legends of Tomorrow Season 2 soon, but in the meantime, watch the first trailer below.
