Battle Harem

A subtrope of the Harem Anime genre, where the male lead has a harem of potential love interests, all of whom are some sort of Action Girl. Sometimes the harem may appear in a form of Hero Secret Service or as an Amazon Brigade.

Because this is a more action-oriented subgenre, Battle Harems are less likely to be focused on romance, but still provide plenty of Fan Service. Often this appears in the form of a Supporting Harem.

Anime & Manga

 * Mahou Sensei Negima has over 20 women, most of whom are Action Girls in some form or the other, and most of the rest being at least Plucky Girls or otherwise quite useful in some way.
 * A Certain Magical Index: Among the girls interested in Touma are a human repository of thousands upon thousands of spellbooks, the third most powerful Esper in Academy City, a sword-wielding priestess, one of her spear wielding subordinates, a magical spy/courier who wants to seduce him into working for her country, and the pre-teen leader of a magical cabal. It's even Lampshaded; some people are starting to wonder if, with all the powerful women he's recruited to his side, he's setting up some kind of resistance force.
 * Mouse is a Harem Anime comedy that consists mostly of scenes about hilariously over-the-top heists Sorata pulls and scenes where his accomplices/servants, ahem, lavish attention on him in a hilariously over-the-top fashion.
 * Tenchi Muyo OVA - is a series about one guy living with five girls, who're all in love with him consisting of: Ryoko, Washuu, Ayeka and Sasami, and Mihoshi.
 * Along with the other Tenchi stuff, there's Tenchi Muyo GXP. By the end, it's the captain, eight girls and an overpowered starship fighting pirates.
 * Rosario + Vampire: All the harem members are capable of holding their own in battle and spend much of the first season defending Tsukune. Justified in that while Tsukune is human, the girls are all Cute Monster Girls - the possible exception is Moka, who needs Tsukune to take off her rosario in order to fight at full strength but even without that she is pretty strong. The show, while very fanservice-y, does also have a strong focus on romance especially in later arcs.
 * Aiki features only Action Girls that Joukyuu is training.
 * Sekirei features a main lead with a harem of busty action girls with elemental superpowers, and was fittingly promoted by FUNimation as "the breast action harem anime of all time".
 * [[Ranma Â½: Ranma Saotome's Unwanted Harem is full of Hot Amazons and Action Girls. Not surprising, since he lives in a world where everybody gets their own style of martial arts.
 * Infinite Stratos: As his co-homeroom teacher Maya once stated, with his force of six representative pilots, he has more than "enough to start a war."
 * Maji De Watashi Ni Koi Shinasai: More true for the anime with Miyako, Wanko, Yukie & Chris already in Yamato's harem from the start, and the Momoyo (and others) in play. In the game, each girl has her own route, though in the Ryuuzetseran route, you get.
 * High School DxD: The more girls who join in the Occult Research Club, the more girls Ise gets.
 * Kore wa Zombie Desu ka?: The harem consists of a Necromancer, a Magical Girl, three Vampire Ninja.
