Both. You can do instant aerial regular teleport if you think the trait activation is coming.
I also forgot to mention that Martian Manhunter also has the best back dash punishment in the game. If you place an MB orb behind Zod, he gets juggled if he back dashes. You can then hit-confirm instant aerial regular teleport. Even if Zod does not back dash, though, he cannot back off and Martian Manhunter can activate trait, get in, and do whatever he wishes. Martian Manhunter's interactable object control is also on par with Zod's.
I am not calling anybody out, but if you are using Martian Manhunter and you are losing to Zod, you are not good. You either do not understand your character very well or you are playing the match terribly wrong.
Even the most basic Martian Manhunter can be tough for Zod. I was fighting @
MK_Chameleon online earlier. His Martian Manhunter was a lot more difficult for me than his Raven, who was his original main character.
By the way, Martian Manhunter beats every zoning character 7:3, which includes Cyborg, Raven, Sinestro, and Zod.
