Berserk Button: Simply looking at Oblivion's Shadow. This is one of the worst possible things that can happen.
Broken Ace: Everyone loves him, and he is The Chosen One of Arceus... Except there is the constant risk of him turning into a Void Pokemon if he experiences something traumatic enough. Even the God of Victory doesn't know if he could win that battle, and let's not get started on Darkrai. Furthermore, it is hinted that he at least indirectly caused the cataclysm, as well as killing Misty, and no matter how many gods are on his side, they can't do anything about his mental state. A mental state which is so fractured, mind you, that the Mirror of Truth in Fichina shattered upon seeing Ash.
Broken Messiah: After Misty is killed by "Lord Null" (Oblivion's Shadow pre-cataclysm), which both Darkrai and Null know is absolute rubbish. Either way, he turns into a Void Human.
Butt Monkey: Tends to have shades of this from time to time, from having an Aura technique backfire upon him, turning his hair pink, to being body swapped with Tiny and repeatedly subjected to Manaphy's water attacks.
Chaste Hero: The only person he shows interest in romantically is Misty.
The Chosen One: The general consensus of him by the gods and several others. Specficially, he is a kind of Super Soldier created from the spiritual level by Arceus to fight the First Evil in case it ever got out. The original series (yes ALL of it) was a training exercise to give him fighting experience and a Chronic Hero Syndrome.
It Sucks to Be the Chosen One: The general consensus of him and those who know what the role truly means. In summation, fight the First Evil and clean up the Legendaries' messes until it comes out of its can. It also means putting everything else in his life on hold when those two things happen.
Cosmic Plaything: He has this opinion of himself but it's more like he's the Cosmic Go-To-Guy for any problems the legendaries have.
Despair Event Horizon: Suffered a tremendous one in the backstory after most of his True Companions were horrifically killed by one thing or another during Lord Null's final attack that led him to become a Person of Mass Destruction. Everyone around him wants to prevent this from happening again, as the more he recovers his memories by finding the Macguffins of the story, the more he comes screaming back to another one. He himself advocates killing him to prevent him from becoming a Void Pokemon.
Dysfunction Junction: As the story goes on and Ash's underlying mental instabilities resurface, he and his team starting sliding more into this. Most poignantly, he was responsible for destroying the world in his past life.
Genius Ditz: He's the reincarnation of Ash Ketchum, so obviously he would be naturally talented at battling, Aura using and the like. But, on the other hand... well, he's Ash Ketchum. For example, he thinks that a haiku is a type of sushi and he is completely ignorant of the Creation Story.
Hurting Hero: So, so much. It's not enough that he watched everyone and everything important to him get brutally annihilated in his past, but add in the fact that Oblivion's Shadow is implying that his very existence is as a result of him, the person who was responsible for said destruction, and that he could easily turn into an unstoppable force of chaos with enough trauma, (of which he has no short supply off).
Indy Ploy: An advocate of making up the plan as you go.
The Leader: Originally it was a moot point because Team Aurabolt only had one other member but now he's a Type IV: he has so many allies because they all like him so much. Interestingly, he's also the opposite of Type II (-2) because his state of mind is the least stable.
Lightning Bruiser: Hit hard, hits fast, and he's the most amazingly agile member of the group.
Made of Iron: He is a Steel Type after all, and it's implied that his experience as a fighter has escalated his capacity for this.
Remember When You Blew Up a Sun?: He killed the Legendary Birds, Darkrai and Cresselia when he was a Void Human. He also was responsible, with Oblivion's Shadow, for the original cataclysm. Leo repeatedly reminds him of both because they're the most awesome things he's ever heard of.
Simple Staff: Aquires a traditional aura guardian staff in Barbedo's grottle and uses it to great effect.
Sanity Slippage: Uncovering the truthh about his past life pushes him furhter and further into madness.
Sanity Strengthening: When he is told that Oblivion's Shadow is Mewtwo's dark side and that the good side is Fighting from the Inside, he gains a better grip on his rage and becomes more mentally stable. This is because he can view the fight as a doubleteam of himself and his brother against an evil spirit that needs an aura purge instead of a fight to the death against pure evil.
Super-Powered Evil Side: His shadow/void persona. Unusual for the trope, its only been used once in the main narrative and everyone from Ash himself to the Big Good to the Big Bad doesn't want it to happen again.
Ash's adoptive brother. A skilled Master Swordsman who has inherited an ancestral sword, dating all the way back to its creator Raikou. The Only Sane Man in the team.
Everyone Calls Him Barkeep: His name is Pikachu, which is weird in this world, as most people have their own name. Justified as it's a family tradition. He has to earn his own name. It's revealed in Chapter 63.
A nerdy and fat but intelligent Squirtle who becomes the first new member. He inherits his undead father's Cool Shades and carries a Chekhov's Armory in his shell.
Adorkable: The biggest nerd in the entire team, by FAR.
Ascended Fanboy: He spent his entire life playing games, reading books, watching shows etc about heroic adventures, pirates, ninjas and magical girls. Now he's a heroic adventurer, travels with pirates and a ninja, and has a Cute Witch for a girlfriend.
Cool Shades: Which function as a Pokedex and a few other things. In fact, it's what his family is known for.
Chekhov's Armory: He has one in his shell. A Running Gag is the cast's reactions to all the werid shit he has stuffed in there 'because he might need it someday.' A short list includes: Every game console ever made, a mirror, a laptop, diapers, a holy relic, heart medication, a hang glider and a parachute (depending on how far away the ground is) and the costume he uses in his guise as a cultist nun. Most of them have been useful.
Cloudcuckoolander: He genuinely comes off as being mildly insane at times, and he thinks the world follows the same rules as the entirety of the TV Tropes database and JRPGs in general.
Crazy-Prepared: In addition to his Chekhov's Armory he has gigabytes of information on countless subjects from anime to medicine to martial arts to fictional languages. Pikachu challenged him to a duel of hyptothetical situations and lost.
Gangsta Style: Abused to hell and back in the Tournament Arc as part of his disguise; he periodically tries again afterwards only for his disgruntled team mates to make him stop.
Genre Savvy: To put it mildly. He guessed Dawn's entire backstory based on the fact that she's a ninja, and knew Ash and Pikachu's quest before they told him. He's predicted most of the plot twists. He quotes and even puts to example multiple Tropes.
I Know Mortal Kombat: Leo can fly / run a train car through a Bullet Hell without taking a scratch because he beat Touhou on Ultra mode. However he learned how to hack Nihilator computers by hacking government ones in his spare time.
Legacy Character: He thinks he's one of these, both in trying to live up to his warrior father's example and his namesake, as he was named over a local expy of Leonardo the Ninja Turtle and takes that as an inspiration.
Lovable Nerd: He has every sterotypical nerd behavior and the nicest guys around.
The Rival: With Chobin, and still doesn't take it seriously.
Science Hero: He's extremely good at making gadgets and devices out of available stuff, rivals and outwits master Mad Scientist Doctor Tarantulas, and he himself borders on a mad scientist in his own right.
Seen It All: Genre Savvy type. No matter what just happened, he'll smugly say he saw it coming because he's seen it in a dozen stories.
Talking the Monster to Death: Justified; he negiotiated the monster to death in Turtle Town.. Lacking the strength and power of the others, this is a tactic he likes to fall back on.
Weak, but Skilled: Holds his own in battle despite a lack of training and basement fat due to his impressive knowledge and Chekhov's Armory.
A cute but traumatised mute Larvitar who was reduced to silence after a terrifying childhood. His aura is impregnable until Ash and the rest of Team Aurabolt warms up to him. Evolves into a Pupitar during the Pirate Island arc.
Has Two Daddies: Tiny, who's still trying to figure out the specifics of T-Bone and Ash both being his father, the former married to his mother, the latter not quite there with his respective womon, and exactly what family arrangement he's supposed to be shooting for.
No Social Skills: Wild pokemon; not big on manners. She sees them as entirely pointless.
Spider-Sense: Like all Absol she can sense danger but there's a catch: she can't tell what kind of danger it is. She can only put her feeling on a scale of two values: probability that something bad will happen and severity of what will happen.
A Misdreavus and abused daughter of Bellum. She eventually has a Heel-Face Turn encouraged by Ash, proving she is a powerful witch. Evolves into a Mismagius after she marries Leo and the curse binding her to Giratina is broken.
Ascended Extra: In two ways. She was both a Character of the Day in the anime, and one of Bellum's daughters originally in the fic, who barely got any screen time as either. Then she betrayed Bellum, joined Team Aurabolt, and is much happier for it.
Berserk Button: When she sees Bellum savagely wound Fantina, the one person who acted like a true mother to her, she SNAPS.
The Ingenue: Played with. While she's not in the least sheltered and has done horrific things, she's naive about life beyond a witch's minion and still possesses the same sense of gentleness and innocence.
Ojou: Heir to the Yukihime family estate (because her mother and older sister were banished) which includes status, land, and magical power. She only cares about the later to protect her real family and doesn't give a shit about her heritage.
Even Oblivion's Shadow finds it irritating that he keeps finding the Nihilator hideouts and killing their residents.
Screw Politeness, I'm a Senior!: He forgoes such niceties as 'not eavesdropping on his companions inner thoughts' because he's a paranoid old man. "I'm older than you, so I can do whatever I want."
Self-Imposed Challenge: In Chapter 63, Briney fights Shadow Entei in Hyper Mode. He doesn't consider that enough of a challenge, however, so he promises not to use his psychic powers, his magic powers, his hammer, the move Explosion, or three of his arms. And he wins.
Took a Level in Badass: Pikachu and Leo agree that he's already so badass that he can't get any more badass unless he evolves into a Metagross which terrifies him because it involves fusing with another Metang and merging personalities. He considers this a form of death.
He evolve into Metagross eventually after getting over this fear.
A recurring ninja Buneary who eventually joins Team Aurabolt, becoming Pikachu's loyal servant and love interest. Later on she becomes happy enough to evolve into a Lopunny.
An Ice Person: Has Ice-type attacks naturally and then is is given a portion of the Element of Ice's power.
The Fettered: The most important thing to her is her ninja code, personal honor, etc. Everything else, including her own physical well being, is second.
To Be Lawful or Good: While she is a good person at her core, she clings tighter to rules than anyone else in the main party. She has done, and will do again, any manner of Dirty Business to uphold her oath and orders.
Sarcastic Devotee: Becomes this by the Fichina Arc. Her loyalty is still high grade but she talks back and/or ignores as necessary.
Super Mode: Ice armor in the style of the Slicer."
The Voiceless: Her vocal cords were cut as a baby so she talks with clicks. Darkrai arranges things so that once she evolves she'll be able to talk.
Oblivion's Shadow (aka Mewtwo)
We take pride in our evil. There are many villains who would deny their evil, to try and justify their actions... but let's face it, we're trying to release the Ruler of Evil and destroy the world. How can that possibly be justified?
Oblivion's Shadow, he's lying.
Leader of the Nihilators and the Big Bad of the fanfic. A masked figure who floats above the ground, Oblivion's Shadow wishes to release the imprisoned demons trapped beneath the mysterious door under Treasure Town. It turns out he's actually Mewtwo. In the past he built a valley for his Clone Pokemon, only to be framed by a Mew imitator that he was planning evil operations there. The valley was annihilated with all the Clone Pokemon murdered. The trauma caused his mind to split into two, the evil half becoming Oblivion's Shadow.
Big Bad: The leader of the Nihilators and the one the heroes fight again.
Big Brother Instinct: The reason he spared Ash and friends 1,000 years ago as Lord Null and spent all the years since trying tto cure Ash's Superpowered Evil Side AND why he held back when fighting Ash in Treasure Town is because he's technically Ash's older brother and a good friend of his from Pre-Cataclym days.
Mewtwo's mind split in two when the clones he was sheltering were attacked and wiped out by an army of legendaries led by a Mew impostor. Mewtwo's darker half became Oblivion's Shadow, and his good half is Gardevoir's blur-friend.
Evil Plan: Destroy the world or something similarly evil. At first; later on it's revealed he has something more well-intentioned going on.
The Faceless: His mask only shows the person speaking to him. He also speaks in their voice.
Foregone Conclusion: His plan will fail. Everyone knows this. But he continues with his plan anyway, because he would rather lose his way than win on another's terms.
[[spoiler: Heel Face Door Slam: After making it very clear that Oblivion's Shadow has completely and utterly lost, Mewtwo says that he could surrender, kill the Nihilators, and join Team Aurabolt to prevent the Ruler of Evil being released. Oblivion's Shadow is actually considering this... before the Ruler of Evil puts a stop to that.
Large and in Charge: He's about the size of a human; given the size of most Pokemon, this lets him tower over many of his subordinates.
Mind Rape: A specialty of his in general, and most explicitly the effects of the Anti-Life Equation.
My God, What Have I Done?: When he killed 108 captive children in a failed attempt to coerce Gardevoir into giving up the rebels, he freaked out over it. Then she accused him of making her ruthless and he freaked out over that too. It turned into an Ignored Epiphany but he was made to confront some awful truths about his operation.
Necessarily Evil: His plan, to kill the Ruler of Evil instead of freeing it, relies on Mesprit converting negative emotional energy (pain, suffering, etc.) to positive energy, and to force-feed it to the Ruler. Of course, to do so, he needed to cause enough suffering to have enough energy.
Only Sane Man: In the Nihilators, he is the only one with the slightest vestiges of sanity. Of course, even that is debatable due to his Villainous Breakdown and his schizophrenia with Mewtwo.
Pride: He admits that his plan has a slim chance of success, and further, that there's a less messy alternative to the same goal that has a higher chance of success but insists on doing things his way because if he's going to fail he'd rather fail on his terms than someone else's.
He seriously contemplates surrendering in Chapter 63. A pity that the Ruler of Evil doesn't.
In chapter 59, it got even worse for him. Possible Illusion Mom left him, and he saw that he might not actually be the Big Bad and that his actions might well be predetermined and planned by something else. He did not take it well. He could not even get angry after his scenes with Gardevoir.
He left the room, guided every step of the way by the tug of the invisible strings of the puppetmaster of his fate, unaware that with every breath he was drawing closer and closer to the damnation he surely deserved...
The Mad Scientist of the Nihilators, Dr. Tarantulas is a corrupt scientist and former associate of Professor Oak. He enjoys experimenting on his test subjects, builds giant mechs, and has a complex relationship with his assistant Chobin.
Moltres, Zapdos and Articuno appear as unrepentent monsters. Often squabbling amonst themselves, these three are working with the Nihilators For the Evulz, traumatised by their experiences in the Crisis Wars. They also happen to be Ash's number one enemies for murdering his friends and mother in the previous world.
The infamous Killer Game Master from Latias' Journey, back now as a reality warping demon guarding a fortress that contains the key to Tiama's lair. He remembers his encouters with Ash, Pikachu and Leo in his past life and becomes a major villain, but has yet to cross paths with Oblivion's Shadow.
Implied to be the Bigger Bad of the story. A traitor to Arceus, Giratina was imprisoned along with countless other demons in the Door beneath Treasure Town. However, Oblivion's Shadow and Bellum plan to release her at some point.
The Starscream: Turned traitor believing Arceus loved Mew more than he loved her, leading her to become the Ruler of Evil's second-in-command.
The Ruler of Evil
A Manipulative Bastard with incredbile powers of simple persuasion, the Ruler of Evil kicked off the Crisis War after turning endless people into demons and promising them eternal freedom from any form of law or control. He also built a massive reality-consuming planet called the Gaiavore which he planned to become the omniverse itself. Defeated by Latias, Rayquaza, and The Power of Love weapon created by Arceus. Imprisoned in the Abyss with Giratina.
Eldritch Abomination: The Ruler of Evil, and Gaiavore - a living, growing, reality-consuming planet made up of two more abominations named MBlock and Missingno, whose life and death cycles kept in perfect balance with each other.
Manipulative Bastard: Manipulated the opinions of endless amounts of universes to become his worshippers and then demons, using fake promises of omniversal peace, freedom and love for all if they followed him.
There are two Latias in the story. One is the Physical God Guardian of Light and the heroine from the fanfic's prequel. The other is the mortal Latias living on Earth. The guardian Latias possesses the body of the second to guard Pokemon Square, combining the two into one character. Latias is still infatuated with Rayquaza, and has a daughter named Bea.
Bad Ass: Just as badass as she was in Latias' Journey.
Deus Exit Machina / Holding Back the Phlebotinum: The Guardian of Light could kill Oblivion's Shadow in one hit, or renew the seal on the Door under Treasure Town, or find the seven Star Badges, or even find Giovanni and Team Rocket... if the summoning ritual hadn't been messed with, making it impossible for her to leave Kanjohenn.
Physical God: Already a legendary, she absorbed tremendous power in the previous story and is now on this level.
Psychic Powers: They're so powerful she could kill everyone in Pokemon Square simply by being in it.
Time Abyss: She's older than the universe; indeed, older than the deity who created it.
Like above, there are two Latios. One of them is the Guardian of Hope (currently fighting evil on the opposite side of the Omniverse), and the mortal Latios, who is Latias' brother and disapproves of the mortal Latias' relationship with Rayquaza.
The Unfavorite: He really doesn't have a high opinion of himself, but it actually makes sense. He loses his sister to the Guardian of Light (an alien force which he doesn't understand at all), he has to watch her and the Dragon God-King fall in love (which he doesn't like one bit), and he has to deal with the constant knowledge that he is essentially nothing but a third wheel in the eternal romance of Latias and Rayquaza. Suddenly his inferiority complex is actually justified.
Latios: Latias and Rayquaza, the great and holy dragon gods...and their tagalong brother, Latios. Whoopee.
Latias: Is that what you really think of yourself? That our fates are so dissimilar?
Latios: How can I not? You and Rayquaza being together is all the Draconians seem to talk about. The two of you have reincarnated constantly together, supposedly one of the Omniverse's longest-lasting romances. Where am I in that legend? What part is there for me to play in your story?
Rayquaza / Bagon
There are two Rayquaza in the fanfic - the Dragon God King and the guardian Latias' mate (currently missing), and the mortal Dragon King who has a crush on the mortal Latias. Transformed into a Bagon part way through to help bring the guardian Latias to Earth.
A Shedinja that works for Rayquaza as his Number Two. Also Bellum's ex-husband and Lily's father. Later he marries Missy when she announces being pregnant.
Badass: His introduction scene includes manhandling two dragons and the narration notes that he didn't earn his current position through nepotism.
Dark and Troubled Past: His anger issues stem from when he and his brother Koga split apart, with Nuken deliberately taking all of the sociopathy and rage that existed within them to give Koga a normal life.
The Dreaded: Everyone who knows of him (with two exceptions) is pant-wettingly scared of him. He invokes this trope to scare others into doing what he wants without getting his claws bloody. From Rayquaza's Trial of Mercy in Chapter 65:
Nuken was currently wrapped from top to bottom in chains of the strongest and heaviest metal known to Pokemonkind, floating in the middle of a containment spell of the kind used to hold archdemons or toxic materials deadly enough to destroy the world, with several dozen of the most powerful guards in His Excellency's service and a hundred ninjas all keeping their weapons trained on him, ready to strike if he so much as twitched the wrong way. Not a single Pokemon in the room doubted he could still break free and murder them all if he so chose, despite the security measures.
Morality Pet: His girlfriend later wife Missy, who is perky and friendly and the only one he will listen to that isn't his liege lord.
Noble Top Enforcer: Inverted. Rayqueza is beloved for his benevolence and Nuken is the terrifying second-in-command who gleefully does his dirty work.
Not So Different: Lily's chief fear is that he will be just as controlling as his ex-wife and her fears are justified as he planned to put her in a Gilded Cage at Rayquaza's Palace so she wouldn't be in any more danger.
Number Two: To Rayquaza in both domestic and military affairs.
Overprotective Dad: He is not at all happy to learn that Leo is after his daughter. He might have killed the Squirtle right then and there if a Relationship Upgrade between him and Lily wasn't the only thing that could break her curse.
Secret Keeper: For a long time he was the only one to know that the mortal Rayquaza in the fic was a Bagon that stepped in to replace the real mortal Rayquaza who was killed by Bellum pre-series.
Sociopathic Hero: By his own admission he is a "monster that happens to be on the opposite side of the other monsters."
A beautiful resident of Pokemon Square, Gardevoir is kidnapped by the Nihilators early on and has since spent most her time in captivity. Has been transformed into a vampire by Darkrai and a vampire from another universe.
Dark Is Not Evil: While Gardevoir is transformed into a vampire, she maintains her sense of good and plots to bring down the Nihilators from the inside.
Tsundere: Like Ash, she denies being in love with him.
Why Did It Have To Be Bug Pokemon: Misty still has her fear of bugs, but with good reason. Misty was kidnapped and brainwashed by the minions of the Insect Queen to think she was a bug and completely subservient to the queen. Her rescue and rehabiliation are traumatising for her. Her new place in a nicer hive mind is not all fun for her.
The god of Death and many other things. Plays a small role early in the story until He admits to being the one who sent Sasha to join Team Aurabolt and is plotting to bring down Oblivion's Shadow on his own.
Religion of Evil: Inverted. Darkrai's religion was once a pleasant religion based on terrifying yet completely harmless mischief. Then the latest generation of priests became obbessed with some tacky and melodramtic vampire novel for teens and changed things. They wrecked the place, changed the decor to emphasize shock factor instead of dignified horror, and treated Cressila like she had forced Darkai into their marriage. By the time Sasha reaches his temple, the teenage followers have completly taken over and turned it into a rave for goths and emos to do all sorts of naughty things. She quickly turns things around and shows them what it truly means to follow Darkrai.
The Strategist: He has more than a small hand in the adventures of Team Aurabolt, especially after Sasha joins.
A group of pokemon that formed on the way of their journey to save the world from an evil organization by collecting sacred macguffins. If this sounds familar it's because they're all expies of Team Aurabolt.
Can't Catch Up: Ash and Ritchie start on more or less even terms but Ash quickly becomes greater and greater
