It is most notable for its unique battle system (a pseudo-fighting engine as a nod to the other entries here), curious character choices, and the protagonists' stories continuing in Endless Frontier: Super Robot Wars OG Saga, with the sequel Endless Frontier EXCEED even continuing the story of the original characters. And because of this, you can find the complete translated script here. Yes, the game is THAT text-heavy.
Also notable for its (fantastic) opening sequence, which was animated by Production I.G and appears to have been directed by Hiroyuki Imaishi (of Dead Leaves, Gurren Lagann and Panty & Stocking with Garterbelt fame).
A Spiritual Successor and sequel would come years later in the form of Project × Zone for the 3DS, with Sega joining Namco and Capcom for the ride, along with Nintendo in that game's sequel.

Tropes associated with this game:
- Achey Scars: The scar over Reiji's temple begins to agitate him whenever Saya (the one who gave him the scar) is near.
- Action Commands: To bias the game towards the player, you can time button presses when an enemy attacks you, recovering AP. Get at least eighty percent of the attacks matched and you recover 2 AP. Note that you'll spend an average of 3-4 each turn and guarding only takes 1.
- Action Dress Rip: More like action dress strip, as Felicia was initially wearing an evening dress, then immediately throws it off before the enemies come.
- Action Duo: Many usable units consist of a team of two characters, some from the same series (Mega Man & Roll, Ryu & Ken, Klonoa and Guntz), some from different series by the same company (Wonder Momo and Bravoman, Guy and Ginzu), and some cross-company (Felicia and King).
- Adaptational Badass:
- The nameless protagonist of Dig Dug was rechristened as Taizo Hori note and turned into a Cool Shades-wearing badass on par with that of Captain Falcon, while also being Masuyo's ex. He's the current trope picture.
- As a whole, you could argue that many characters got this treatment, or at least had their moments. For example Joka, who is The Dragon to Ghadius in his home series, is now The Heavy, forging alliances and proving to be a much more clever threat.
- All the Worlds Are a Stage: The final stage consists of worlds that the characters have visited all joined and mashed together thanks to the Big Bad. The level sees you fighting nearly every major villain who had previously been killed in the events of the story — short of Grandmaster Meio, who had been killed in the previous chapter, and M. Bison, who was killed by Akuma instead of anyone in the party — before finally facing 99.
- Amusement Park of Doom: Joylant reappears and serves as a pair of stages.
- Anime Theme Song: "Brave New World."
- Asian Fox Spirit: Xiaomu is a 765-year-old Chinese werefox, whereas Saya is a Japanese werefox.
- The Atoner: Xiaomu actually was the one who killed Reiji's dad, but the latter doesn't even blame her for it because he already knew it. So he channeled his rage on Saya instead who forced Xiaomu to kill his dad in the first place.
- Background Music Override: Judas is the only boss encountered, barring the final one, who uses a specific theme for his turn rather than standard theme every other boss uses on their turn. It also spoils his true identity, not that it isn't obvious anyway.
- Badass Crew: Your team consists of an unrivalled gathering of heroes and fighters from many worlds, from world-class martial artists to special agents and much more. Frankly, the only thing lacking is an actual name for the team.
- Battle Couple: Most notable with Reiji and Xiaomu, but there are a lot of examples in this game.
- The Battle Didn't Count: Bosses tend to retreat upon defeat. Subverted with Joka and Janga, for as much as they escape, for them its mostly a case of Know When to Fold 'Em.
- BFG: Masuyo's gun. It's called Wave-Motion Gun but only fires in shots.
- Big Bad:
- Saya, given her role in the plot as well as her ties to Xiaomu and Shougo Arisu, Reiji's Disappeared Dad. Then it's revealed that the true Big Bad is Kyuju Kyu.
- Beyond Saya, there are several other villainous groups working with their own agendas. Astaroth and Druaga are working in tandem with each other, with Astaroth seeking to expand the Infernal Village's domain and Druaga seeking revenge against Gilgamesh for his original death. Meanwhile, Yoritomo and the Genji Clan act of their own accord before choosing to side with Druaga. M. Bison has teamed up with Grandmaster Meio to aid him in his goal of dominating all the worlds. Zouna only starts acting in the endgame, after most of the other villains are gone, with the intent to use the Dycroft to destroy the Material World. And working with all these villains are their own underlings and several other freelance villains in between, such as Joka and Janga, Black Bravo Man, and Lord Raptor.
- Big Damn Heroes: Akuma saving Sakura at one time, and defeating M. Bison at another time.
- Brick Joke: Oh so many. One example at the beginning of chapter 29 (lampshaded mercilessly by both Sakura and Karin):
- Xiaomu: "And another funky place we turned up in. Where the heck are we? Somewhere near Renma?"Reiji: "You really think this looks like the middle of a city?"The payoff (after Saya appears)Saya: "Oh my gosh. Just look at this place. Where are we? Ishigami'i Park?"Reiji: "You really think this looks like the middle of a city?"
- Boss Rush: The final stage. Justified in that the merging of worlds is bringing bosses Back from the Dead.
- The Cameo: Statues of Pac-Man can be seen in front of Namco Theater in Chapter 1.
- Canon Immigrant: Reiji, Xiaomu, and Saya would eventually crossover into Endless Frontier, another series developed by Monolith Soft.
- Catchphrase: In the Fan Translation, Reiji will almost always say "How felicitous." Comes with the territory.
- Chekhov's Gun: M.O.M.O's costume from Sylphie allows her to steal items. She doesn't get to use it till she needed to steal one of the MacGuffins from Devil Kazuya.
- Cloning Blues: Katana, a product of the Ouma Project, is the clone of Saya. Their physical resemblance is questionable.
- Clothing Damage: Arthur, true to his origins, gets stripped down to his undies when sufficiently damaged. He can actually invoke this on himself to quickly change out of armor.
- Cluster F-Bomb: According to the GameFAQs fan translation, several characters are like this (or at least a T-rated version of this), most notably Mitsurugi and Gantz. Both of them use an extremely crass and rude way of speaking (the former is basically a Samurai version of an Arrogant Kung-Fu Guy and the latter speaks like a thug/delinquent). It's more of a translation adaptation.
- Color-Coded for Your Convenience: Allies leave maps with white smoke, enemies leave maps with black.
- Combatant Cooldown System: The game has a system similar to Final Fantasy Tactics—a unit is able to act once it has earned 10 AP, which accrues at 1 per turn for each unit on the map. The player can estimate the initiative order by looking at the numbers above each unit; whoever shows a "1" is the next to act. Different actions cost different amounts of AP, so a unit that only moves will act again sooner than a unit that moves and attacks. There are other special actions to spend and earn AP; for example, units may spend AP to reduce damage from enemy attacks and time Action Commands during enemy attacks to regain AP.
- Combination Attack: Multiple Assaults, where a group of 2 or more units gang up on single or multiple foes. Sometimes these overlaps with There Is No Kill like Overkill, and sometimes are followed sometimes by Ass Kicking Poses. Unfortunately, the Multiple Assaults can also fall under Awesome, but Impractical since they have a fixed damage, and by that point, you could literally kick ass to enemies up to how many thousand hit points from one turn. If you know when to use them, however, you can kill multiple enemies with one attack.
- Combining Mecha: Unknown Soldiers 1P and 2P from Forgotten Worlds are accompanied by the Mobilsuits from Side Arms: Hyper Dyne. Just like in their namesake game, Side Arm α and Side Arm β are able to merge into a powerful form (this only appears in their Zetai Gattai Multiple Assault with Sylphie, the shopkeeper from Forgotten Worlds).
- The Comically Serious: When Janga from Klonoa Heroes calls Guy a pain in the ass. Guy's response?"A pain in the ass? Such things are irrelevant in battle."
- Cool Big Sis: How Morrigan is portrayed towards Lilith.
- Cosplay: Aside from possessing an arsenal consisting of various weapons and items from Capcom arcade games, Sylphie also can dress up as (and copy the techniques of) four other Capcom females: Street Fighter III: 3rd Strike's Makoto, Michelle Heart from Legendary Wings, Linn Kurosawa from Alien vs. Predator (Capcom), and Mai-Ling from Red Earth. She also gets to sell two Magical Girl costumes to MOMO (one for a Rare Hunter skill, the other for a Limit Break).
- Every time new characters meet, they think the other person is cosplaying.
- Crazy-Prepared: Saya is this in a nutshell. Anytime Reiji thinks he got her cornered, she finds a way to get out of the mess and comes up on top. Same goes with Joka, who plans on escape and brings up many back-up plans.
- Crossover Couple: Taizo Hori from Dig Dug and Toby Masuyo from Baraduke used to be a couple, but divorced several years before the events of the game. They're begrudgingly working together to save the multiverse, to mixed feelings on both ends.
- Cutscene Power to the Max: Ken can perform the Shin Shoryuken in a cutscene, something he can't do it in gameplay afterwards. It might be a nod to Brainwashed Ken from the mid-90s SF anime movie and Violent Ken from SNK vs. Capcom: SVC Chaos, where he could do all sorts of wicked stuff. It could be argued that as one of the top practitioners of Gouken's style, Ken has learnt at least the theory of all of his school's moves.
- Debut Queue: The first few chapters are prologues introducing a few characters from each realm. These characters then disappear for a few stages after the prologues are over, to deal with Reiji and Xiaomu's group until they join later. In fairness, they're from different dimensions entirely, and Reiji and Xiaomu are the main characters, but still...
- Determinator: Reiji and a few of the protagonists in the opening movie are shown collapsed in defeat, but one by one, they all force themselves to stand back up and launch their most powerful techniques against Saya.
- Dinosaurs Are Dragons: Invoked, but defied; when Allosaurus appears, Gilgamesh wonders if it's a dragon, and his partner Ki notes that they should prepare for its fire breath. They come from a Heroic Fantasy setting with actual fire-breathing dragons, so their confusion is justified, but Karin quickly corrects them.
- The Ditz: Sakura has many moments that fit this trope nicely.
- Dumb Is Good: Felicia was convinced that King was a were jaguars, despite King telling her over and over that he was just a luchador wearing a mask.
- King is a subversion. He's much smarter and more level-headed than she is, but that doesn't stop him from thinking Felicia was also just a neko cosplayer.
- Elemental Powers: Obviously, given the cast. Between Reiji and Xiaomu, however, almost all of your "standard-fare" powers are covered by their moveset. Xiaomu's Suiren is icy; Xiaomu's Sword Beam, her gun Silver, and the lasers that come out of her fingertips are of the dark element; Reiji's Gold and Xiaomu's Byakkohou are light; Reiji's Karin and Xiaomu's grenades are fiery; Reiji's Chirai is electric.
- Enemy Mine: A few of your foes (the ones who are on the wrong side involuntarily notwithstanding) will decide to join forces with you when bested. To be exact, Waya-Hime, Cammy, Rose, Judas, Lilith and Armor King. And Heihachi.
- Foe Romance Subtext: Definitely Reiji and Saya. To the point that the other party members mistake Saya as Reiji's ex and believe the two are going through a very violent breakup.
- Genre-Busting: A turn-based-strategy fighting game.
- Gratuitous English: Some characters when their turn comes up. Most notable are Felicia ("Retsu dansu!") and Demitri ("Retsu purayu...").
- Gunpoint Banter: Between Reiji and Saya at the end of Chapter 4. Nothing quite like two people shoving the barrels of their guns in each other's faces and still being able to carry a conversation.
- Guns Akimbo: Reiji uses a pistol and shotgun. Xiaomu? Two pistols. Both also carry swords which they use in concert with their guns.
- Hammerspace: Hsien-Ko's sleeves are filled with an infinite number of weapons (even including her partners' firearms, which she pulls out for her MA). She explains that even after she throws her weapons, more appear in their place.
- The Heavy: Joka. He's arguably the most active of all the villains, spreading the "sleeping sickness", invading a Holy Place of Worship while Janga distracted everyone, making repeated attempts to get sacrifices for Druaga and the Soul Edge, and seemingly knowing what's really going on what with his last words being a hint towards Kyuju Kyu's "Mingling of Worlds".
- Heroic Sacrifice: At the end of the game, Reiji attempts to pull one to destroy Kyuju Kyu once and for all but suddenly, every single character goes Big Damn Heroes and suggests him to just beat the stinking crap outta her.
- Pretty much everyone at somepoint, this being a Banpresto game and all. Even Reiji has his moments when he's not in snark mode.
- The two most surprising ones are Kurino Sandra from The Legend of Valkyrie and Mike Haggar of Final Fight. Both are fairly minor characters (and in Kurino's case a fairly subdued one), but their voices in combat are easier louder then half of the cast.
- Humongous Mecha: Jin's Blodia, which is "borrowed" by Sylphie.
- Incredibly Lame Pun: There's one level where magic causes everyone to start speaking in these. Needless to say, for the characters, it gets old really fast. Lampshaded by the characters and the game text (the text has the puns in red).
- Infinity Plus One Equipment: Sylphie's Dress is this. It costs 9999 G, however it raises all stats by 25. Naturally, you can only get it before starting the final chapter.
- Interface Spoiler: If the main chapter objective shows up before any bosses show up on the field and one of the lose conditions includes a specific player unit to not be KO'd, then you know that a boss unit that's from the same series as that unit will show up soon.
- Irony: Hsien-Ko the Jiang-shi is paired with a Resident Evil protagonist.
- Katanas Are Just Better: Expect a good deal of characters either have the real deal (i.e. Mitsurugi, Kagekiyo, Reiji, Saya, etc.) or a slight variation of it (e.g. Taki and Waya-Hime use kodachi, Xiaomu has a shikomizue, Ginzu uses a ninjato, etc.).
- Kiss of Death: Saya's super begins with one.
- Laser Blade: Apparently, Strider Hiryu's Cypher. Naturally, the same would go for Strider Hien's double-bladed cypher. Overlaps with Hot Blade.
- Leeroy Jenkins: This is practically Jin's modus operandi whenever he meets Devil Kazuya.
- Magic Knight: Xiaomu and Saya, justified by their status as mystic foxes. Also, Valkyrie.
- Magic Skirt: Wonder Momo's miniskirt never raises above her legs; it's noteworthy mostly because her original arcade game was famous for constant panty shots.
- Magikarp Power: Practically almost everyone is a Magikarp Power incarnate when the player first gets a hold of them, the only exception being KOS-MOS, who's busted from the start. Helped a lot by the game's systems putting itself in your favor.
- Mascot RPG: Like many of the games in this crossover-happy sub-genre, this game was both by Namco and a Strategy RPG.
- Massive Multiplayer Crossover: Naturally. Interestingly, the game Multiverse has about 4 or 5 actual worlds; meaning that many games already took place in the same setting; if they're similar enough.
- More Dakka: The aforementioned Zettai Gattai, where Sylphie combines the Mobilsuits of Side Arms: Hyper Dyne into a more powerful form. The new mecha, alongwith the Unknown Soldiers and Sylphie (who has taken on the form of Michelle Heart from Legendary Wings) do not waste time in opening fire upon their foes. The unlucky victims are greeted by storm of bullets, followed by a FREAKING GIGANTIC LASER BEAM.
- There's also the Multiple Assault between Bruce McGivern, Fong Ling, and Regina, as Hsien-Ko provides them with various firearms, notably shotguns, submachine guns, flamethrowers, grenades, missile launchers, and a gun that fires lightning bolts. Then she drops her steel balls and nearly kills all of them...
- Mundane Utility: When the world is finally going back to normal and the people who were left behind are from the real world, Ishtar's power gets used as a taxi delivery system.
- My Death Is Just the Beginning: Saya went ahead and let Reiji shoot her so that Kyuju Kyu can finally pass through.
- Nemesis Weapon: Reiji wields a weapon rack consisting of 2 elemental swords, a Sawed-Off Shotgun and a revolver. His Arch-Enemy, Saya, also wields a weapon rack of 3 elemental swords and a Grenade Launcher. Saya is also the one who killed Reiji's father.
- Ninja Pirate Zombie Robot: Evil undead Genji warriors, who gain control of a race of tentacle aliens.
- The Allosaurus is heavily implied later in the game to have been infected with the T-Virus.
- Noble Demon: Red Arremer Joker, who seems to be the main character of Demon's Crest (Firebrand in America).
- Nothing Up My Sleeve: Played for Laughs. Hsien-Ko's Multiple Assault provides Bruce McGivern, Fong Ling, and Regina with enough weaponry to make the U.S. military jealous... and then she gets worked up and accidentally drops spiked maces over them, and a frying pan on Bruce's head.
- Odd Couple: The sullen and snarky, but well-meaning Reiji and his much, much older partner, the upbeat, flirty, and overprotective Xiaomu.
- One-Steve Limit: This game has both MOMO from Xenosaga and Momo Kanda from Wonder Momo. To avoid confusion, the latter is usually referred to as her superhero name, Wonder Momo.
- Original Generation: Reiji Arisu, Xiaomu, and Saya. Also, Dokumezu and Dokugozu, Katana, and Kyuju Kyu.
- Pile Bunker: Dig Dug's Taizo Hori wields a giant one.
- Plot Tailored to the Party: Whenever the cast splits up, the Gnosis will conveniently only attack the groups with KOS-MOS or MOMO and Shion in them so they can cast the Hilbert Effect.
- Power Creep, Power Seep: The most striking would be Wonder Momo; who is an actress playing a magical girl; who actually becomes one for no actual explained reason other than Heart Is an Awesome Power.
- Ragtag Bunch of Misfits: Fong Ling and Regina even lampshade it when they were first thrown into a new world. Let's see: two high school students (Sakura and Karin), three spies (Bruce, Fong Ling, and Regina), a wrestler (King), a pop star idol, an undead Chinese girl (Felicia and Hsien-Ko, respectively), two teachers (Hideo and Kyoko), three people from the future (Shion, MOMO, and KOS-MOS), another pop star idol (Wonder Momo), a businessman (Bravoman), and two underground secret agents (Reiji and Xiaomu). Yup, can't get more ragtag than that. And, to top it all, that line is from Stage 5 or 6 (not including the prologues) AND with only about 5% of the playable cast in your party.
- Recurring Boss: Nearly every single villain fall under this trope as they always flee when defeated until their proper death in the plot.
- Rule of Symbolism: During Reiji's Battou Ougi Shinra Banshou super (Shinra Banshou being a Buddhist idiom meaning "all of creation"), he and Xiaomu take a page from the Chinese concept of the Five Elements. Basically, their dialogue (with the two mixing up the exact phrases and who says what from time-to-time) proceeds as such:"Wood fuels Fire!""Fire creates Earth!""Earth bears Metal!""Metal carries Water!""Water feeds Wood!"
- Running Gag:
- The real nature of Felicia's fur bikini.
- Also, Felicia constantly referring about King as "a fellow Darkstalker" despite King explaining her over and over that he isn't a Darkstalker, he's just a human Luchador wearing a jaguar mask. This long running gag also serves a a setup for another joke, as King (after complaining endless times about how dumb and dense Felicia can be) suddenly realizes that Felicia is a Darkstalker instead of a woman cosplaying as a cat as he believed all along.
- The supposed Love Triangle between Reiji, Xiaomu and Saya. It's not like that, really. Though, in fairness, the tension between Reiji and Saya is palpable, and Xiaomu does care for Reiji a fair bit. Case in point, her kiss at the end of the game.
- Sequel Hook: Demitri tells Morrigan and Lilith that Jedah is coming back. Sure enough…
- Sidelined Protagonist Crossover: None of the game's Rival Schools reps are Batsu, the main character - instead there's Hideo Shimazu and Kyoko Minazuki.
- Speaking Simlish: Subverted with Klonoa (who has this as a signature trope); Namco opted for him to speak proper Japanese instead. This is because the incarnation of the character appearing in the game was the one from Klonoa Heroes, one of two Klonoa games (three if you count the language track option in the Door to Phantomile remake) where the characters spoke a proper language instead of the language relating to this trope.
- Spectacular Spinning: To the point of being able to create lightning in Klonoa's case. Baby and Mack also fall into this category with the majority of their attacks. A number of other characters follow this trope as well.
- Spotting the Thread: In chapter 40 where seven members of the group get cloned. There's just one problem, the real Chun-li is also with the assault team, yet she also got cloned.
- Sword and Gun: Reiji, Xiaomu, and Saya. Reiji, in fact, has two swords and two guns, as well as a shotgun. Xiaomu's blade is actually a cane sword. Saya also wields a M203 grenade launcher and probably beats them out in terms of sheer firepower. She also holds three katanas. And all of their swords have elemental affinities. Rule of Cool, much?
- Upgraded in Project × Zone where artwork confirms that Reiji has three swords in his arsenal plus Gold and Hollywood (his revolver and shotgun).
- Sword and Sorcerer:
- The prime example would be the Battle Couple Gilgamesh and Princess Ki, the latter taking her magic abilities from The Return of Ishtar.
- Reiji and Xiaomu are a downplayed example: Both are competent in melee and long-ranged attacks, but Xiaomu has fox magic for her attacks.
- Theme Music Powerup:
- Whenever one of your units' turns comes up, music from their series will play.
- In addition to being the one song Yuzo Koshiro arranged to represent Tales of Destiny in this game and thus being used for all the Tales heroes, "Lion - Irony of Fate" will always override the "enemy turn" music whenever Judas appears as an enemy.
- Token Evil Teammate: Heihachi Mishima. Arguably Morrigan, Demitri, Mitsurugi and Tron Bonne. Though most of them fall into Anti-Hero.
- Tokyo Is the Center of the Universe: Not quite, as the game involves hopping through dimensions. However, a ferocious battle two rival organizations took place in Shibuya, Tokyo ten years ago, setting up the backstory of the protagonists (notably, Reiji). Ten years later (in 20XX), temporal and spatial fluctuations occur in Shibuya, setting the plot into motion.
- Tonight, Someone Kisses: How the game ends; Xiaomu kisses Reiji while commentating that smoking is bad for kisses.
- Took a Level in Badass: Many characters and enemies, have naturally been given this treatment due to the games nature, making every creature no matter the origin or style a threat. Moos and Grizzes from Klonoa, for example, were just fodder that walked around pretty innocently and shot slow moving projectiles (respectively), here they can surround their enemy and slash at them with their claws and fire exploding bullets (respectively).
- Underground Monkey: Many Mooks.
- Verbal Tic:
- Xiaomu has a tendency to add "-jya" (じゃ) to the end of her sentences.
- Guy adds "-de gozaru" to his speech at times, just like a stereotypical ninja.
- Hsien-Ko sometimes adds "-aru", like a Chinese character in an anime.
- The Voiceless: Tekken's King and Armor King in Namco x Capcom have no voice acting (but they do get text dialog). It gets silly with the later, for he doesn't get any pre-/post-battle quotes (at least the former has Felicia covering him up) and thus ends up standing there being mute.
- Waddling Head: Moos, Pookas, Octies, and so on.
- Walking Armory: Hsien-Ko is the most blatant example of Hyperspace Arsenal. In this game, she's revealed to hide various firearms belonging to her partners in her giant sleeves as well, all in addition to the more traditional weapons that she is normally associated with.
- To a degree, Reiji, Xiaomu, and Saya. See Sword and Gun above.
- Wife Husbandry: Considering Xiaomu is 765 years old while Reiji's in his 20s...
- Working with the Ex: Taizo Hori and his ex-wife Toby Masuyo. Although they divorced long ago, Toby still has mixed feelings about Taizo.
- World of Pun: There's a stage where every character is making lame puns. All of the puns are highlighted in red, to boot.
- Yōkai: Most of the game's original series enemies are based off Yokai or other Asian mythological monsters, such as the Kamaitachi. Saya's sidekicks are these guys.
- You ALL Share My Story: Because this game's storyline splits the universe not into the individual worlds of the 26 different franchises, but just into five general realms, so many characters from separate franchises are suggested (or stated outright) to actually know (or at least know of) each other beforehand. Because so many examples exist, they have to be separated between worlds. And even when barely accounting for any of the villains, the list of connections can still be quite massive.
- Material World 20XX: Bravoman is familiar enough with Wonder Momo's shtick to know that it's based off a real transformation like his own. Speaking of Wonder Momo, she's booked as part of something called the "Battle Musical" with Felicia. Karin Kanzuki's family sponsored this Battle Musical performance themselves. Oh, and Felicia travels with King II. Who has wrestled Mike Haggar for the CWA title. Haggar's friend and fellow Metro City hero Guy has formed an Action Duo of Bushin-Ryu practitioners with Ginzu, even though the latter is part of a super crime-fighting team from the future. We'll get on the future in a bit, but on the topic of Guy, Sakura Kasugano recognizes him (as he does Akuma; both are understandable considering FF has been incorporated into the SF universe), and they both know professors from the Justice Private Academy at Klin Village despite having never attended the school. Meanwhile, US-STRATCOM agent Bruce McGivern recognizes Regina by attire as a Secret Operations Raid Team agent. His fellow spy/possible girlfriend Long Feng is friends with fellow Chinese lady Chun-Li from Interpol. One of the companies they're all investigating, Heihachi Mishima's financial group, employs Dr. Bomb as a chief scientist. Another, M. Bison's Secret Shadowloo Society, has stolen data from the Mishima Zaibatsu for use in Bison's experiments, which has resulted in gaining the ability to clone the likes of Ogre. Finally, Reiji Arisu, Xiaomu, and Saya have information on most if not all of these people, whether through their duties as Shinra/Ouma agents or Xiaomu's eccentric interests.
- Distant Future: Hiromi Tengenji has graduated space fighter school and Masuyo Tobi is now her superior officer in the United Galaxy Space Force. Oh, and they've been tasked to arrest Tron Bonne and her Servbots. As in Mr. Driller, Masuyo is Amicable Exes with Taizo Hori, who retired from Drilling and became a Digger with Mega Man Volnutt and Roll Caskett. Strider Hiryu and his enemies recognize KOS-MOS's Hilbert Effect, with Strider Hien and Tong Pooh clearly putting out that their forces, who now include the minions of the late Scumocide, already have or know of another source of it. All these characters recognize Captain Commando and his Commando Team as the magnificent heroes that they are.
- Fantasy World: Lolo, the Omiko, and Valkyrie all serve the goddess Ishtar, adding their might to that of her favored Lady and Knight Battle Couple Gilgamesh and Ki. Speaking of, those two have not only worked with Arthur in the past, to the point he's considered the Silver Knight to Gilgamesh's Golden Knight, they're all regarded as legends by the likes of Klonoa and Guntz, Sandra and Sabine, and even Stahn Alleron and Rutee Katret. After Stahn and Rutee failed to retrieve the Eye of God from a friend of theirs who stole it for some desperate purpose, said weapon would be stolen again by Black Valkyrie, who is all too aware of its power. Said friend, Leon Magnus, is later revived and corrupted by Black Valkyrie (as are Rose and Armor King, but that's just the wall between worlds crumbling).
- Spirit Realm & Makai: Unlike in her host series, Morrigan Aensland has not inherited Makai; things in Hell are actually run by Enma-Daio and his ferryman Andaba. She has an easygoing relationship with them, whereas her vampire friend Demitri Maximoff wants to kill Enma-Daio for the spot and is constantly irritated by Andaba's habit of mispronouncing his name. Enma-Daio and Andaba are also connected with Boss Bull and Tarosuke, the latter of whom they trust enough to assign him as Taira no Kagekiyo's partner in the latest rehash of revenge mission against the evil Minamoto clan. And Otohime of the Dragon Pavilion Castle has one of the three amplifier artifacts Kagekiyo needs for this quest. Furthermore, both the Minamoto clan and the rival warrior duo of Mitsurugi Heishiro and Taki are hunting after a certain evil soul-eating sword known as the Soul Edge.
- Joka is constantly flip-flopping between many villains sides, keeping tabs on their activities, gathering souls, trying to find sacrifices to Druaga, Trying to obtain the Soul Edge, and so on. He constantly attacks the heroes, sometimes gaining bits of information as he does so. He brings Janga as his partner, and manages to fight alongside many heavy hitters such as M. Bison, Saya, Yoshi, Benkei, Red Arraemer Joker/Firebrand, Lord Raptor, etc. with his Moos and Druaga's men.
