The world's third-smartest man, and the superhero known as Mr. Terrific. A millionaire and scientist, Michael is an expert in many, many fields. Prior to the events of the series, he had journeyed to Earth 2 on an undercover mission for Batman, leaving his company, Terrifictech, in the hands of Karen Starr (Power Girl), who unbeknownst to him had returned to Earth 2. He returns during the Dark Multiverse crisis, and later finds that Stagg Industries has acquired his company and with it, the technology to enter the Dark Multiverse.
Michael uses "T-Spheres" — supercomputers in floating spheres adorned with his symbol — as well as his intelligence to fight crime.
- Adapted Out:
- His status as the second Mr. Terrific has been removed, as there (so far) wasn't ever a Golden Age of heroes, and Earth 2's Mr. Terrific was a villain who Michael didn't base himself off.
- Badass Normal: No powers to speak of, but he's skilled in all fields. He's basically Batman but with some flying orbs instead of batarangs.
- Expy: He's the Reed Richards/Mr. Fantastic of the team, being the super smart member of a team of explorers.
- Hollywood Atheist: He's rather dismissive of religious beliefs on rational grounds.
- Jerkass: He's more interested in scientific research than helping his friends.
- The Lost Lenore: He still misses his dead wife, Paula.
- Science Hero: Uses his tech and brain to save the day.
- The Smart Guy: Well, he is the third-smartest man in the world, and is easily the most analytical member of the team.
- Token Minority: The only non-Caucasian member of the team.
An adventurer who was transformed by the Orb of Ra. He is in a relationship with Sapphire Stagg.
Rex has the ability to change the chemical makeup of his body, as well as its shape.
- The Big Guy: The most physically imposing and strong member of the team.
- De-Power: After the fight with Algon, he turns back into a human. But at the end of #12, he returns to save Mr. Terrific.
- Expy: He's the Ben Grimm/The Thing of the team, being the super strong, deformed big guy who has a civilian love interest, while also not getting along with the more childish member of the team.
- Locked into Strangeness: In #12, as he was about to destroy the scepter of Ra that gave him his powers in a Tragedy Of Impulsiveness, he gets an SOS from Phantom Girl, and opts to instead become Metamorpho again, destroying the staff in the process.
- Reality Ensues: When he loses his powers, he finds it impossible to have a normal life due to the years he spent as both Metamorpho and as a mercenary, thus not having enough experience to get a regular job.
- Star-Crossed Lovers: His main motivation is getting home to Sapphire, who is a universe away.
A former criminal exposed to a mysterious chemical, Plas ended up helping Batman explore the Dark Multiverse. This experience left him as a dormant egg, and only when he was re-exposed to Dark Multiverse energies was he restored to his normal state.
Plas has the ability to shapeshift, and his body is extremely malleable. He is also immune to Dark Multiverse energies.
- Avengers, Assemble!: Go Terrifics, Go! (Metamorpho thinks he needs to change it.)
- Deadpan Snarker: He's the most humourous and immature member of the team.
- Expy: He's the Johnny Storm/Human Torch of the team, being the most humourous and fun, while also having a rough relationship with the resident big guy.
- Parents as People: When he gets the chance to be awake again, he goes to Angel and Luke, trying to apologize, but they don't want to hear it. However, he did somewhat manage to mend things with Luke by riding the Batmobile together.
- Rubber Man: So much so that he can stretch to get a bird's eye view of a giant being while standing on it.
- Took A Level In Jerk Ass: He's really pissed that nobody bothered to wake him up, or even tell his family. He's still his immature self, but he's clearly got a chip on his shoulder.

- Expy: She's the Sue Storm/Invisible Woman of the team, being the one female of the group, as well as having powers related to tangibility.
- The Heart: When the Terrific's made plans to disband, she was against it due to this. In #12, Plastic-Man and Metamorpho come to her SOS without a second thought. (To clarify, Eel cut father/son bonding time short, and Rex became Metamorpho again, for her.)
- Hotter and Sexier: Inverted. Linnya's costume is very obviously based on Phantom Girl's Retroboot costume, but Tinya's shutter-style Cleavage Window has been filled in with black.
