New transfer student Theseus arrives at the Prometheus Academy, tracking the Minotaur as his alter ego the Grim Avenger. Hercules isn't sure of the new hero's style, but the two will have to team up to defeat the monster.
Tropes:
- Claustrophobia: The minotaur apparently is claustrophobic; he says that he hates labyrinths and gets all sweaty while he's in his own. However, he doesn't do much to prove he can safely remain out of one. The Olympians send him back after Hercules and Theseus track him down at the end of the episode.
- The Cowl: Theseus faces the Minotaur as the "Grim Avenger", complete with costume, faux-Batman voice, secret hideout, and constantly referring to himself in the third person. (In the movie, Theseus was stated to be one of Phil's long-gone pupils.) Predictably, this leads to conflict with the more classically heroic Hercules.
- He Who Fights Monsters: Herc becomes more and more anti-heroic as he deals with the Minotaur, to the point where he seemingly plans to kill the creature, despite trying to control the Grim Avenger's darker tendencies earlier. Theseus talks him down from the edge, saying that, "Neither of us wants to be like him."
- It's Personal: Hercules wants to capture the Minotaur and return him to custody on heroic principle for most of the episode. However, then the monster crashes a school party and injures Icarus. After Herc recovers from the initial horror, he goes on a Roaring Rampage of Revenge, much to Theseus' shock.
- Let's You and Him Fight: Hercules winds up fighting Theseus, even though they're both heroes who should be united against the Minotaur. Herc later refers to "[getting] in a fight with a wrong guy" as a "rookie mistake".
- Meadow Run: Cassandra, who has developed a crush on transfer student Theseus, imagines them running across a beach to each other. The fantasy ends up subverted when the relationship doesn't go anywhere.
- Meaningful Echo: Theseus, as the titular superhero, tells Herc to "lead, follow, or get out of the way", before adding that he intends to lead, so that one is out. Later, Herc, angry and determined to track down the Minotaur, tells Theseus, "Lead, follow...just get out of my way." Theseus' expression indicates he wasn't expecting Hercules, who has been trying to rein him in the entire episode, to react this way.
- Out-of-Character Alert: Icarus is shocked to see the otherwise stoic Cassandra swoon over someone, namely Theseus.
- Series Continuity Error: In the film Phil mentions that Theseus among the other heroes he trained, but failed in the end. Yet he appears here as a dark counterpart to Hercules.
