Sunday VS Magazine Shuuketsu Choujou Daikessen

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 Konami for a Crossover game with characters from these two eponymous magazines; a Fighting Game 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 Hudson Soft, and published by Konami for the 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.

Sunday VS Magazine provides the examples of:

 * Alternate Company Equivalent: This game to Jump Super Stars, and the fact that it's for the PSP to the other being for the Nintendo DS.
 * Badass Normal: Joe, Ippo, Takamura and Tiger Mask; three boxers and a wrestler whose abilities and skills are 100% normal, compared to the others at least.
 * Boobs of Steel: Miu, she is one of the few female playable characters, her fighting style is martial arts based, she is physically the strongest out of all the women, and of course her bossom is the biggest around too.
 * Breakout Character: 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.
 * Charles Atlas Superpower: Hayate, Noboru and Koutaro; three individuals who can basically achieve limiless levels of strenght by just training that hard.
 * Defeat Means Playable: 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.
 * Excited Show Title: Sunday VS Magazine: Shuuketsu! Choujou Daikessen
 * Follow the Leader: Publisher Shueshia was the first before Kodansha and Shogakukan to celebrate decades of success with a crossover fighting game, with Jump Super Stars and Jump Ultimate Stars.
 * Marth Debuted in Smash Bros: Noboru, Ichirou and Koutarou were absolutely unknown in the west when this game was released, since then at least Noboru 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.
 * There's also a literal case, Natsu and Lucy's voices were first heard here in this game, the Fairy Tail anime would only premier 7 months later in Japan, and the voice actors are the same.
 * No Export for You: 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.
 * Popularity Power: 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.
 * Punny Name: Boss, the Final Boss; the original character for the game has a name just like that, although the japanese might find it less generic due being Gratuitous English for the them.
 * Secret Character: Many, out of the complete 30 playable characters roster, only 12 are available from the get go, but most only requires finshing 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.
 * The Smurfette Principle: 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.
 * Spiritual Successor: 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.
 * Squishy Wizard: Negi, his character is that of his earlier portrayal in the manga, with little to no fighting skills, prefering magic projectiles and his staff for long ranged attacks. No absurd DBZ-level of fighting coming out of him in this game.
