- A Good Name for a Rock Band: Steel Crescent Syndicate.
- Crazy Awesome:
- Metal Man is a sawblade wielding lunatic who nicknames everyone and fights the mob with his blades. He doesn't attack people but only because he can't mess up his blades by getting blood all over them. At one point Proto Man, Cut Man, and Guts Man have to drag him to safety because he insists on having an epic Bonnie and Clyde-esque last stand against the cops.
- Dust Man is a Cloud Cuckoolander who drives around in a creepy old van, fights pests and animals around the Skull Fortress, spends his time scaring the other Robot Masters with weird ghost stories and his general weirdness, and has a vacuum cleaner as a weapon.
- Crosses the Line Twice:
"Game over, Ring! Pull out!"
- Ring Man trying to hit on Roll in "Mega Pinocchio", which ends in her trying to shoot him in the face.
- Evil Is Cool: The Steel Crescent Syndicate's robots, in sharp contrast to Wily's bumbling minions (excluding Proto Man and Elec Man).
- Idiot Plot: It's lampshaded repeatedly that the conflict in "The Mega Man in the Moon" could be solved in seconds if the president and Senator Wolfe just got over themselves, stopped causing problems with the UN, and let Duo deal with Wily. It's actually enforced; the Syndicate wants the R.I.P to stay out of America and are manipulating things to keep them away.
- I Knew It!: The author noted in the author notes of "The Mega Man in the Moon" that several fans managed to correctly guess that Senator King is working for the Syndicate.
- She also gave credit to readers for correctly guessing that "The Great One" is actually Ra Moon.
- Jerkass Woobie: Snake Man.
- Memetic Mutation: "It's not a banana!" Explanation
- Moral Event Horizon: Dr. Wily trying to fire the Lunar Laser on New York, at least in Proto Man's eyes.
- Nightmare Fuel: Has its own page.
- Rewatch Bonus: Everything about Senator King after The Reveal in "The Mega Man in the Moon".
- Rooting for the Empire: Some readers want Wily and his robots to win, or at least win out against the Syndicate.
- Sympathy for the Devil: For many readers, Proto Man is a sympathetic antagonist due to a variety of factors, which vary from his personality, his relationship with his siblings, his background to his current situation. It's strongly implied that his unhappiness stemmed from being forced to live a quiet lifestyle which clashed with his thrill-seeking personality, and this in consequence made him escape Dr. Light's home and work with Dr. Wily. It's entirely possible that if Proto would have found a different outlet for his need for excitement, he wouldn't have gone rogue. On top of that, even if working with Dr. Wily suits him well for the moment, the chapter "20,000 Leaks Under the Sea" hints at Proto Man's fear of losing Dr. Wily, the only person who can repair him, and being forced to go back to Dr. Light. It's easy to forget that Proto Man depends on Wily for what is essentially his health. Add to that his genuine fondness for his siblings and their constant refusal to join him and you can see why some people feel sorry for him in spite of his unapologetic behavior.
- Tear Jerker: Has its own page.
- The Woobie:
- Mega Man. Holy crap. The poor kid just wants to perform science experiments but instead is constantly forced to fight Dr. Wily and his forces, with all the physical and psychological issues that entails. He develops massive self esteem issues and begins to wonder whether he's a human or a robot. He has to deal with constant family problems and his brother tries to kill him on a regular basis. It's very hard not to feel bad for the guy.
- After "Bot Transfer" Snake Man has become this, with his brief time in Mega Man's body expanding his thinking and worldview considerably... but his usual body isn't equipped to handle such processes, and in "Bad Day at Peril Park" he's confronted with how lousy and counterproductive some of Wily's schemes really are.
- Uncanny Valley: Oil Man has a liquid-like design and a creepy face reminiscent of old cartoons.
- Unexpected Character: The author has plans to include every Robot Master in the series, but some cameos were more unexpected than others.
- Time Man and Enker appear in "Bot Transfer" as members of the International Robot Police, and Time Man mentions Duo several times throughout the episode. They also have Ra Thor, Knight Man, Cloud Man, Sword Man, Centaur Man, Gravity Man, Flame Man, Wind Man, and Tornado Man.
- The Steel Crescent Syndicate has Burner Man, Oil Man, Slash Man, and Ballade among their ranks.
- Jewel Man cameos in "The Mega Man in the Moon" as a clerk at a jewelry shop while Astro Man appears defending the Lunar Laser. Dyna Man, Volt Man, and Sonic Man, from the DOS game, are mentioned as robot criminals that were destroyed in the past.
