Billy
- Ascended Extra: In-universe. At the beginning of the third season, he begins appearing as a regular at Torrington, after gaining a Full-Body Disguise that makes him look human (even though's he's about one foot and six inches tall).
- Dark and Troubled Past: You can't be a former space pirate overlord, and not have this.
- Hey, It's That Guy!: Billy is Dean Venture.
- Little Green Men
- Running Gag: He always appears out of nowhere on missions, scaring the main trio.
- Samuel Vincent
- Space Pirates: Once the leader of a vast army, but it became too much for him, and after years of behavioural adjustment at the Center, became the Billy we know and love.
- Talking to Himself: With Martin.
M.O.M.
- Berserk Button: Every single time Martin breaks something in her office.
- Hey, It's That Guy!: M.O.M.'s voice actress, Teryl Rothery, was the first dub voice for Kodachi Kuno in Ranma ½.
- Lethal Chef: It was once suggested that she take up cooking to alleviate her stress. The office looked like it had been attacked, and the "cookies" she baked looked like they were made of sludge.
- Meaningful Name: See "Team Mom" below.
- Only Sane Man: Besides Diana.
- Team Mom: She is Diana and Martin's boss, and seems to be close to them. Still, she got a bit heavy-handed when she once tried to play the role literally.
- The Worf Effect: For being the Center's leader, she does get captured or possessed by many of the Monsters of the week whenever she's involved in a mission, although most of the time, she isn't expecting it.
Marvin
- The Ace: WAS this during his first two appearances.
- Doppelganger: For lack of a better term, of Martin. Ironically enough, Martin's the only one who spots the similarity, while everyone is mostly focused on how great he is (of course, it doesn't stop M.O.M from punishing him for his screw-ups). As The Other Wiki states, he's like a Bizarro version of Martin: similar yet different.
- Greed: Occurs when he intentionally looked for a Leprechaun's charm, in the hope it would bring him good luck. Of course, it results in an Involuntary Transformation into a Leprechaun.
- Recurring Character: Technically doesn't affect the story line in any way, but still is an example. Appears twice in Season 1, twice in season 2, with only one appearance in season 3.
- Spotlight-Stealing Squad: He's this in his first two appearances.
Gerard Mystery
- Skeptic No Longer: After the second time he gets involved in the paranormal (which involves him being possessed by a pre-historic worm), he is finally told of the Center.
- Parental Favoritism: Doesn't mean it, but he does like Diana a bit more than Martin. A bit of a Tear Jerker, considering Martin's his biological child.
- Like Father, Like Son: Subverted, and hard. Their interests are completely the total opposite of each other, which results in some conflict in the episodes he's with Martin, which is both of his appearances (his video call with Martin and Diana on the Christmas episode doesn't count).
- Science vs. Magic: Firmly on the science side, until he finds out about the Center.
- Invisible Parents: Not Gerard, per se, but we never see Diana's mother in the entire series.
Monsters/Villains
This section is dedicated to a select number of creatures (or villains) that Martin and Co come across. The main ones posted here are those who at least appear in more than one episode, or have some significance to a character aside from one-shot monsters.
Gastromo
Gastromo was the first monster that M.O.M ever caught as an agent, and appears in Beast From Within.
- Puppeteer Parasite: forcibly takes over his hosts, and through his touch, can also make other beings his slaves.
- Nightmare Fuel: He might be this to some, since upon taking over his victims, they look like some disgusting slug-human, and turns others into his slaves via worm-like creatures that come off his body.
- Weaksauce Weakness: One linked to real life; slugs can't stand salt, and neither can Gastromo. Also, he consumes so much iron, the host becomes attracted to magnets.
- Big Eater: He makes his hosts into this to an extent, and he prefers to eat raw meat, since he requires a heck of a lot of iron.
Venasso
Venasso was the first monster that Martin Mystery ever caught, sharing that trait with Venasso. Appears in Lovespell from the Underworld.
- Shapeshifting: Venasso's primary ability, is to change her shape. Like a normal chameleon, she can take the colour of her environment, making her invisible. She can also change her shape to look like whoever she wants to, like M.O.M, Vivian Michelle (Martin's first crush), and Martin himself.
- Overly Long Tongue: Of course, being a chameleon.
Djini
One of the few recurring creatures in the series. First appears in Crypt of the Djini, and later on in Return of the Djini
- Jackass Genie: In spades. Wish for a one-of-a-kind statue? She turns you into the statue.
- Our Genies Are Different: Trapped in a purple gemstone skull.
- Hoist by His Own Petard: Can't stop granting wishes, no matter what it is. One time though, another wish is reflected back at her, with similar results.
Two-part Episode Villains
These villains and monsters are notable in the fact that their appearances invoke a two-part episode. There are four such two-part episodes in the series, each one headed by different villains.
Space Pirates
Members of a Space Pirate army Billy once led back when he was Ganthar. They appear in They Came From Outer Space.
- Curb Stomp Battle: Martin and Co are absolutely no match for the Space Pirates, and Billy has to interfere to save them.
- Space Pirates: Obviously. They are a variant along the lines of Metroid Space Pirates.
- Galactic Conqueror
- Kill It with Ice: Highly vulnerable to a fire-retardant like substance M.O.M was extracting from an insect earlier in the episode.
- Shapeshifting: Capable of this, and even morphing into one super-alien.
- Kill It with Fire: After their combined form is frozen, Ganthar tosses them into some computer equipment, making an explosion, destroying them.
- Planet Looters: Upon conquering a planet, they use up all available resources, and move on to other planets to conquer, leaving a line of barren worlds in their wake.
Gatekeeper
Appears in Season 2 Finale, They Came From The Gateway. Due to the two-part episode's nature, it is likely they intended for him to be the final monster of the series, until they continued Martin Mystery for a third season. He is the Guardian of the Gateway, a pool located in Tibet that is the source of all paranormal evil.
- Big Bad: Of the Two-part episode.
- Cliff Hanger: His still being around at the end of the episode. As mentioned above, it is never mentioned what happened next during Season 3.
- The End - or Is It?: At the end of the episode, he is seen in the now shut down Center, eying Martin and M.O.M's U-watches. This is after he was supposedly frozen outside the Gateway in Tibet.
- Omnicidal Maniac: As part of his nature, upon corrupting M.O.M with the Gateway's power, he turns all the creatures within it against the Earth, aiming to plunge the world into an eternal world of darkness.
- Our Liches Are Different: Appears to be an undead spirit, and is humanoid in appearance, matching the standard appearance of Lich.
- They Wasted a Perfectly Good Plot: Not exactly, but after his The End - or Is It? moment at the end of the episode, we suddenly jump into Season 3, with no explanation as to how he was defeated again, or how Martin and Co, and M.O.M found out he was still alive.
- Ultimate Evil: While we do see him, he does fit the bill, considering he's the guardian to the Gateway of the Underworld, the source of all Paranormal evil.
Borack the Faceless One
An entity located in another dimension. He holds dominion over all shadows, and surfaces once every 1000 years to attempt a take-over of the world. Appears in the two-part episode, Day of the Shadows.
- Big Bad: Of this Two-part.
- Eldritch Abomination: Takes the form of a living shadow, and upon the day of his take-over, he is able to drag nearly every living being on the planet into his Shadow Dimension when there are shadows around them. Martin, Diana, Billy, and Kaitlin (Martin's temporary girlfriend), only escape this fate due to being around light on the initial night of Borack's awakening.
- Living Shadow
- Fate Worse Than Death: While in his realm, everyone is being slowly turned into shadows themselves.
Octavia Paine
The series' official final villain. She is also one of the few human adversaries that Martin and Co have come up against. Appears in the series finale, It's Alive.
- Big Bad-Of This Two-part.
- Badass Long Hair
- Bitch in Sheep's Clothing
- Blondes Are Evil
- Contemplative Boss
- Disproportionate Retribution: She was fired from the Center for not being a good enough agent. Her response? Spend years creating an Ultimate Monster to destroy the Center, and get revenge on M.O.M.
- Evil Mentor: Is one to Diana, who she decieves into joining her organization.
- Faux Affably Evil
- Manipulative Bitch
- Not So Different: Attempts to use this on Diana to get her to join her, after revealing her true nature.
- The Rival: Has a history with M.O.M.
