- Adorkable: The player character from Diabolical certainly acts this way in some scenes. For example, some of their evil plans seems more like harmless pranks than anything else and at one point after hearing their name mentioned on the news, they bounce up and down on the couch in excitement.
- Anticlimax Boss: In Slammed!, Paul Prototype can be knocked out with one punch in the championship match at Ring of Valhalla.
- Base-Breaking Character: Breden from Choice of Rebels. This is particularly due to their romance being partially forced upon the player, and how the player has to practically beat them off with a stick to reject them. There's also the possibility that they're The Mole.
- Black-and-White Morality: In "Choice Of Robots", members of the military are considered "evil" because they kill people. Anyone supporting, helping or otherwise not being completely against the military is just as evil as they are, including the player character if they decide to create military robots.
- Complacent Gaming Syndrome:
- While some games are generally better about it than others (Mecha Ace, for instance, sets gameplay-affecting stats at character creation and only shifts them in a few extraordinary circumstances afterwards), stats, particularly "opposing-poles" stats that reduce every time the player chooses the other option, both go up when the player choices of a particular type and offer a higher success rate for a higher stat. While this theoretically keeps the player "in character," making the choices consistent with a character's personality, in practice it also encourages a very uniform set of choices throughout the game, since choosing anything else could permanently gimp the character, discouraging any Character Development or changing mindsets.
- On a less-meta level, picking the option in line with the highest "stats" is almost always the best choice, whether it's sticking to ranged combat with a high Perception in Mecha Ace or using "acrobatic" moves with high Technique in Slammed!
- Complete Monster:
- Champion of the Gods: Sarpedon is one of the three Vestiges encountered in the story, and easily the worst. Residing on an island in the middle of the Forgotten Sea, Sarpedon regularly causes boats to crash onto his island, and then turns the surviving passengers of said boat crashes into statues that he arranges into his own twisted "art", a process he has repeated onto hundreds of innocents. When you crash onto his island, Sarpedon wastes no time in inflicting this same fate onto your entire crew, and, when you attempt to stop him, Sarpedon happily drains the life force of his own statues, killing dozens of them. Murdering many of the people who try to stop him, Sarpedon uses his last breath to summon a plague onto the nearby city of Kelinos, plunging the hundreds of residents into deathlike comas from which they nearly die if not for your intervention, all just to spite you.
- Choice of Zombies: Anita is a minor villain encountered in the story, yet makes the most of her time to be a truly monstrous individual. Seemingly the kind leader of a group of survivors of the zombie apocalypse who have taken up residency at a church, Anita is actually a religious fanatic who believes zombies to be the next step in human evolution, and, as such, uses her friendly exterior to lower innocents' guards before feeding them to a group of zombies she keeps chained up, releasing any people who reanimate back into the world in the hopes to turn even more people into the "Master Race". Depending on your choices, Anita can try to feed a child to her zombies, and even succeed, all while claiming it is the "will of God".
- Diabolical: Ara-Kunos the Eighth, the emperor of the planet Yod, at some point came to Earth under the alias of Dr. Arachnus and made a name for himself as the world's most infamous villain. Prior to the game, he attempted to steal all of Earth's water supply. When stopped by renowned hero the Star, Arachnus mentally tortured the hero into becoming a borderline insane shell of his former self. Later, he murdered President Alex Johnson by drinking all of his blood, before acquiring the President's clairvoyant powers. Receiving visions that a threat to him was somewhere on Earth, Arachnus went into seclusion while having mechanical spiders kill anybody they come across. When he finds out that you're the said threat, Arachnus infects thousands of people in Merit City with a eventually-fatal nano-virus that turns them into zombie-like drones, all with the goal of killing you. Eventually, he reveals his true identity, and declares that he intends to terraform the entire planet, killing the majority of humans and enslaving any survivors. When you enter his ship, it's revealed that Arachnus shows no sympathy for his people, brainwashing them into mindless soldiers who will die for him without a second thought. When confronted, Arachnus offers you the opportunity to join him, only to mock you for thinking he was being genuine about his offer; if Hackmaster was chosen for your sidekick, she'll attempt to take up Arachnus's offer, only for him to kill her for no reason. In a game that acts primarily as a parody of heroes and villains, Dr. Arachnus is played deadly serious, and out of all the supervillains in the world, proves to be by far the most heinous one the player confronts.
- Hero of Kendrickstone: Milius Black-Clad was once the Grand Wizard for the city of Kendrickstone, but after sacrificing animals and children in order to further his research, he was banished from the city. Enraged at Kendrickstone for rejecting his "genius", Milius began kidnapping and brainwashing hundreds of innocents into becoming his slaves, then using them to lead raids on caravans and travelers coming to and from Kendrickstone, making sure to slaughter as many people as possible during said raids. After promising to spare Kendrickstone should it surrender to him, Milius is revealed to have lied, planning to massacre the hundreds of inhabitants and raze the city to the ground even if it unconditionally surrenders.
- Mobile Armored Marine: Governor Plaxus is the smug, greedy leader of the colonist planet, Far Hope. When contacted by the Lacertians, a race of lizard-like aliens, Plaxus immediately began trading them anything they requested in exchange for their immense riches, and, when the Lacertians began asking for humans so that they could "research" them, Plaxus was more than happy to oblige. When you investigate Far Hope, discovering the houses ransacked, the crops burned, and the thousands of citizens missing, you discover the truth that Plaxus has betrayed his people to the Lacertians, who plan to devour them all, in exchange for granting Plaxus their regenerative abilities. When you confront him, Plaxus happily explains that only himself and the "chosen few" followers will survive the Lacertians' occupation, and eagerly tries to murder you when you express your disgust with him.
- Fan-Preferred Couple: Some romance options are more popular than others, like Hawkins from Mecha Ace or Wakefield from Deathless, or become options because of fan demand, like de Vega from Affairs of the Court.
- One True Threesome: In Hollywood Visionary, it's possible to end the game dating both the Actor and the Grip, although it's difficult, and bringing it up the first time will make one of them storm off; you'll only get the threesome ending if you suffer through this first failure, and then bring up the possibility again at the very end, when both are more open to the possibility.
- This might occur at the end of Slammed! with Ecstasy and Madison, though no resolution is given.
- The Scrappy: A lot of people find Figs from Tally Ho to be a pest. And to some extent, Mopsie as well.
- Ship-to-Ship Combat: Choice of Rebels: Uprising has probably the biggest shipping war, with PC-Breden and PC-Simon/Suzane (depending on gender). It's a bit one-way; both are popular romances, but Breden's a minor Base-Breaking Character and those players who aren't interested in them tend to dislike being forced into a romantic attraction while being discouraged from romancing Simon/Suzane.
- The Woobie: The humiliated Samantha Withers in Choice of the Vampire.
- Jerkass Woobie: She comes off as this, though, if one is playing a Choctaw character, given her earlier racist diatribe against Native Americans, in which she outright calls the protagonist subhuman.
