Superman & Lois has previously revealed that the Nazi villain Atom Man (or Atoman) was the first big bad Kal-El faced as Metropolis' Man of Steel. Now, though, it's looking like he'll make his return in the show's upcoming third season.
As you can see below, the supervillain was spotted battling Superman on set in an episode that's being directed by The Flash star Tom Cavanagh. We're assuming this is the same version of Atom Man we've already met, and that he's once again set out on a mission to attack and destroy Metropolis' multicultural neighbourhoods.
Lots of big changes are coming to Superman & Lois as the series enters its third year on The CW. We recently learned that Jonathan Kent actor Jordan Elsass has decided to leave the show, with Michael Bishop set to take over from him.
Season 2, meanwhile, established that this story takes place in its own reality separate from the Arrowverse. That means team-ups are off the table, though with The Flash nearing its end, there will soon be nothing left for Superman & Lois to actually crossover with!
As you may have also noticed below, Tyler Hoechlin's Superman has a new costume!
The blue is a little darker and deeper than before, while the emblem is now attached to the suit rather than just part of it. As expected, that resembles the logo for the series and gives this costume a big-budget feel. With big screen plans for Superman still up in the air, we'll take what we can get, and Superman & Lois has definitely delivered a great take on this character thus far.
