Publishers ''Kodansha'' and ''Shogakukan'', in anticipation for the 50th birthday of their top magazines: ''Weekly Shonen Sunday'' and ''Weekly Shonen Magazine'', initiated a project with Creator/{{Konami}} for a {{Crossover}} game with characters from these two eponymous magazines; a FightingGame was chosen as the most fitting for characters mostly coming from action {{Shonen}} series.

''Sunday VS Magazine: Shuuketsu! Choujou Daikessen'' is a Crossover Fighting game, developed by Konami Computer Entertainment Aomori and Creator/HudsonSoft, and published by Konami for the [[UsefulNotes/PlayStationPortable PSP]]; released in March 2009 to celebrate 50 years of Weekly Shonen Sunday and Weekly Shonen Magazine history, it features 30 playable and more than 100 support characters from the first years to the latest years of a five decades epic.

The gameplay is centered around simple matches one-on-one, each character can equip one support to use in the matches, and they can string simple combos with standard, special and ultra attacks. The game offers a Quest Mode, a single player adventure where the chosen character fights and interacts with the merged universes of Sunday & Magazine, a simplistic Story Mode so to speak; of course it also has the straightfoward Arcade Mode, and the Multiplayer modes.

The chart above lists all series present in the game, but just [[http://www.youtube.com/watch?v=468YXevlnLE the 30 playable characters]] in each one of them (asterisk {*} indicates a unlockable SecretCharacter), the other hundread supporters will be listed in the {{Trivia}} page, a work in progress.

!''Sunday VS Magazine'' provides the examples of:

* AlternateCompanyEquivalent: This game to ''VideoGame/JumpSuperstars'', and the fact that it's for the PSP to the other being for the UsefulNotes/NintendoDS.
* BadassNormal: Joe, Ippo, Takamura and Tiger Mask; three boxers and a wrestler whose abilities and skills are 100% normal, compared to the others at least.
* BoobsOfSteel: Miu has a martial-arts based fighting style, and is physically the strongest out of all the women, and of course has the biggest boobs.
* BreakoutCharacter: Ban grew out to be a extremely important character as the Get Backers manga progressed, he attained a stable popularity and presence, rivaling or even surpassing Ginji's. It holds true to this game, while Ban is the playable character, Ginji is just a supporter.
* CharlesAtlasSuperpower: Hayate, Takizawa and Koutaro; three individuals who can basically achieve limitless levels of strength by just training that hard.
* DefeatMeansPlayable: All characters that aren't unlocked after beating Arcade Mode, requiring the collection of Sunday and Magazine tickets to buy them, then play Arcade Mode again to defeat them at the final level to unlock them.
* ExcitedShowTitle: Sunday VS Magazine: '''''Shuuketsu!''''' Choujou Daikessen
* FollowTheLeader: Publisher ''Shueshia'' was the first before ''Kodansha'' and ''Shogakukan'' to celebrate decades of success with a crossover fighting game, with ''VideoGame/JumpSuperStars'' and Jump Ultimate Stars.
* MarthDebutedInSmashBros: Takizawa, Ichirou and Koutarou were absolutely unknown in the west when this game was released, since then at least Takizawa and Ichirou can be considered known to small circles, as their series got attention from the {{Scanlation}} community, but Koutarou still remains in the dark.
* NoExportForYou: Licensing this game outside Japan would be a nightmare to the company which wishes to do so, as the series' rights are distributed to many different holders in the west, opposed to the original holders in Japan which are only two, ''Kodansha'' and ''Shogakukan''.
* TheOtherDarrin: The game was released shortly before the ''Manga/FairyTail'' anime came out and gave the characters official voices, so as a result Natsu and Lucy are respectively voiced by Creator/MiyuIrino and Creator/MikaKikuchi rather than Creator/TetsuyaKakihara and Creator/AyaHirano.
* PopularityPower: Newer and popular series got to bring two playable characters with them, in contrast to any series who is already past 10 years of print; case in point being Inu-Yasha, an extremely popular series, but it wasn't fresh for this game anymore. Hajime No Ippo is the exception to the rule due being the longer running epic out of the bunch.
* PunnyName: Boss, the FinalBoss; the original character for the game has a name just like that, although the Japanese might find it less generic due being GratuitousEnglish for the them.
* SecretCharacter: Many, out of the complete 30 playable characters roster, only 12 are available from the get go, but most only requires finishing Arcade mode to unlocking it; the rest are more complicated, the easy characters to unlock are all from fairly new or still ongoing series, the classic characters however, requires multiple playthroughs to collect points to buy, and later defeat to unlock them. Honor goes to Joe Shimamura, the oldest character in the game (debut 1964) is the last one to be unlocked as it requires all others to be unlocked first.
* TheSmurfettePrinciple: True to its action Shounen roots, most series are represented by male characters, out of the 30 playable characters only 5 are female, and they are accompained by the male leads. Narrowing down to series being represented, Kaoru is the only girl leading her series.
* SpiritualSuccessor: to Shueshia's Jump Comics: ''Jump Super Stars'', even with characters and series completely unrelated to Shueshia, Sunday VS Magazine borrows the main concept of having iconic characters, old and new, beating the snot out of each other for little to no reason.
* SquishyWizard: Negi, his character is that of his earlier portrayal in the manga, with little to no fighting skills, preferring magic projectiles and his staff for long ranged attacks. No absurd DBZ-level of fighting coming out of him in this game.
