Martian Manhunter is nowhere to be seen in the two teasers and 50+ photos of CW’s Invasion! crossover starting Nov. 28. As the most powerful hero in the DC extended universe (some would argue more powerful than Superman himself), his absence from the largest crossover event in TV history was questioned by fans. But if this new Supergirl poster is any indication, it looks like he will be joining Supergirl in the Arrowverse, officially meeting heroes like The Flash, Vibe, Firestorm, Green Arrow and Dig.
At this point, it’s unclear if Martian Manhunter will travel by way of breach, or his own devices. The scene where Supergirl arrives to Central City with The Flash and Vibe doesn’t show J’onn is with them. We don’t really know how J’onn escaped Mars and arrived on Earth on Supergirl, though in the comics, it was through an experimental teleportation tech called a zeta tube. Maybe he still has access to it? Straight up teleportation is pretty much the only power Martian Manhunter doesn’t have, although he can go invisible, phase through solids, shapeshift and move objects with his mind.
While the poster isn’t confirmation Martian Manhunter will appear in the The Flash, Arrow or Legends episodes of the crossover, at the same time, it’d be mean of The CW to advertise his presence and not follow through. I’m not sure how you have an all-star team up without J'onn, especially if there are aliens involved.
