* CompleteMonster: [[spoiler:[[BitchInSheepsClothing Serph Sheffield]], when placed in charge of the Karma Society's God Project, began using everyone and anything around him in his quest to [[AGodAmI attain the power of God for himself]]. He uses Sera's growing love for him to push her PsychicPowers into further maturation, only to express disgust at Sera'a creation of a virtual paradise consisting of [=AIs=] she uses to escape the pain of his experiments. When Colonel Beck proposed to change Sera's paradise into a training simulation for creating stronger [=AIs=], Serph overrides Heat O'Brien's warning against destroying Sera's mental condition and tells Beck to proceed. After a desperate Heat pulls a gun and demands the project to stop, Serph tells Heat that a human's mind is no different than a machine, and that each of the subjects, including Sera, [[WeHaveReserves was expendable and could be replaced]], before manipulating Argilla into killing Heat. After being turned into a demon by a heartbroken Sera sending a massive data surge into the now black Sun, Serph goes on a killing spree starting with Beck and Argilla before being killed offscreen. Refusing to accept that he is dead, he re-appears at the EGG facility as Solar Data and tries to kill the [=AI=] Serph and Heat while proclaiming to have the power of God. A cruel and manipulative young man, his actions are largely responsible for the disasters plaguing the series]].
* DamselScrappy: Sera until [[spoiler: she [[TookALevelInBadass gains Atma powers]].]]
* EnsembleDarkhorse: Heat was this to the Atlus staff at least during the first game.
* EpilepticTree - [[spoiler: Satan]] in the second game states that a "heretic is trying to destroy the world." Fans theorize that he's referring to either Aleph from ''VideoGame/ShinMegamiTenseiII'' or the Demi-Fiend from ''Nocturne''.
** The Seraphim appearing in the second game really don't help any. Expecially since one of them - in a factory - says "This is not the factory I knew..." Guess where he was found in the second SMT game.
** [[spoiler: Brahma]] has something akin to the [[VideoGame/ShinMegamiTenseiIIINocturne Amala Drums]] on the heads of his various forms. Let that sink in for a minute. Though it is confirmed inseries he is not connected to [[spoiler:God/Great Will]] by Schrodinger himself.
* FashionVictimVillain - Margot Cuvier's outfit wouldn't look out of place in LadyGaga's wardrobe
* LesYay - Pretty blatant in regards of Argilla and Jinana. Heat even [[LampshadeHanging Lampshades it]] by complaining about how she's upset about her "girlfriend". [[spoiler: This was due to her being forced to ''kill'' a frenzied Jinana]].
* LikeYouWouldReallyDoIt - [[spoiler:Averted.]] When you first see [[spoiler:Roland and Argilla's]] {{Heroic Sacrifice}}s in the second game you'll almost certainly dismiss them as [[HesJustHiding just hiding]] because the game still has a long way to go and, given the way you're encouraged to optimise your characters for specific roles, [[KilledOffForReal killing 2 of them off for real]] would SERIOUSLY handicap your party's effectiveness over the long term. [[spoiler:By the time Gale and then Cielo have been far more conclusively killed off on screen it finally sinks in that, no, ''AnyoneCanDie''- as you immediately see when Serph and Sera, the last 2 characters left, die after them and the final stage of the game effectively takes place ''in the afterlife.'']]
* MagnificentBastard - Jenna Angel is pretty much at the center of every important event in both games. [[spoiler:Taken to its logical conclusion in that she is both Sera's mother ''and'' father.]]
* MemeticBadass: The [[VideoGame/ShinMegamiTenseiIIINocturne Demi-Fiend]] has acquired this sort of status due to him serving as the first game's ever-notorious BonusBoss.
* MemeticMolester: Khumbanda in the second game.
* {{Moe}} - Sera
* MostWonderfulSound - The sound of the karma meter going up after battles, especially after getting a ton of Atma Points.
* RescuedFromTheScrappyHeap: [[spoiler: Sera and Cielo]]
* ScrappyMechanic - Berserk Mode in 2, which happens during higher numbered Solar Noise phases. You can't use magic or items and everyone becomes a GlassCannon. The only thing you can do is use physical attacks (or Hunt skills) or wait a turn, resulting in ''Critical Or Death'' battles. Fleeing is also an option but Karma points get more than doubled if you win.
** Thank god fleeing isn't just an option, but has a 100% guaranteed success rate in Berserk Mode. Also, the developers applied FridgeLogic to the idea of only being allowed to use physical attacks, so your characters ignore enemies' physical resistances and immunities, allowing them to slaughter enemies they wouldn't even be able to TOUCH with physical attacks normally.
* TearJerker - As mentioned in HeroicSacrifice, there will be lots of tears in this game.
* {{That One Boss}} - Cerberus in the first game, Meganada in the sequel. If you beat Meganada, even just barely, the final boss will be cake.
** Let's not forget Ananta. It gets 7 actions per turn, hits you with Dekaja, boosts itself through the roof with Tarukaja and Power Charge, and is smart enough to attack the same person constantly rather than spreading out the damage. Not to mention that it likes starting every turn by casting Sonic Wave, Stun Wave, and Dream Haze in succession. And if you even try to use a Void Physical ability, it rips of Mudo and Mudoon for every attack. No elemental weakness either.
** Anyone remember Vasuki? This thing uses both Maziodyne, an electric spell that can shock your characters, and a unique Ice spell that has a good chance to freeze your characters and, barring crazy preparation, you can only guard against one element and Vasuki is smart enough to attack with whatever isn't blocked. He can also toss in two unblockable [[NonElemental Megidolas]] using the two actions that he gets per turn. Oh yeah, and [[OhCrap he's encountered earlier than Ananta]]. Your only saving grace is that Vasuki is weak to fire, but he has a lot of health and has ailment attacks ready if you brought [[TheScrappy Cielo]] along.
* {{Woolseyism}} - Mostly kept to name changes: the Assignments became the Vanguards, the Merrybell became the Maribel, "Mick The Nick" became "Mick The Slug", and so forth. Strangely enough, they didn't change the names during cutscenes: Gale's map of the Junkyard displays all the original names of the Tribes and Tribe leaders.
** They named one of the Mantra (skill-teaching equipment) "Wikipedia" as a joke.
