If you liked the Sky Girls anime, the Anime-Planet community thinks you'd like:
Due to an invasion of an unknown enemy, the world is being destroyed. The military force is powerless against the enemy, lives are being taken and the planet is being torn to pieces. However, an unexpected turn occurs when scientists create a weapon known as "Striker", which is the perfect fusion of both magic and modern technology. The group of young girls who will master "Strikers" will become Strike Witches, and with their new magic brooms, they will swiftly sail through the skies in order to protect what is left of mankind...
Both are very similar in their themes; where young girls are made to use high tech flying gear to fight against formidable enemies. The story lines differ though and there is a lot of "panties" in strike witches - a bit annoying but still watchable!
Loligirls can save the world! Thats what both shows are about, even though thats about it.
While in Sky Girls, you get some constantly panty showing girls riding a mecha in order to defeat evil monsters, you get some as loud as an airplane magical pantygirls in Strike Witches.
So I bet if you liked one show, you'll fall in love with the other! And if you dislike one, you'll surely hate the other anime even more. I did.
In a world where mankind is at the brink of destruction, one lone scientist has concocted the means to save it: bioroids. These artificial humans coexist with humans in the city of Olympus, under the watchful eye of the supercomputer Gaia -- to stabilize society. The military strongly opposes their use, however, and the elite soldier Deunan may hold the key to saving both the human race and the lives of the bioroids. Teamed up with an old friend, Briareos, Deunan must race against the clock to discover the secret of the Appleseed before countless lives are tragically lost...
Who wouldn't want their own human-sized mecha? In a time of war, humanoid tanks or mecha would be the ultimate weapon, that's for sure; you'd be able to rule the battlefield. If you liked Sky Girls and want more mecha power with stunning good looks, look no further because Appleseed is here. Utilizing CGI at its best, Appleseed harnesses the power of mecha as in Sky Girls, both in flight and on the ground.
In the future, Tokyo has fallen victim to syndicates, trigger-happy people who run rampant and other groups who don't like to follow the rules. In response, an organization called RAPT has been created, whose goal is to maintain their definition of "peace". In the underground, however, science involving humans and powerful mechanics is progressing at a steady phase, but for what purpose? Meet our four angels who know how to kick butt and raise hell whenever it's needed. Their motto? Shoot first, talk later. Their mission? To make the seemingly impossible possible, of course...
Did anyone say girls and mecha? Sky Girls combines skimpy outfits and mecha in one story. Sky Girls is pretty much in the same caliber as in Burst Angel -- "going for the cowgirl look, I see?" If you are looking for a mecha anime series with cool clothing that expresses the characters and has an interesting story, look no further for Burst Angel is here.
Amidst the hustle and bustle of Arkham, a wonderous city built by the powers of magic and alchemy, lie not-so-hushed rumors of a great machine that can be rarely seen in the city. With the newest sighting of this towering robot known as Demonbane, freelance journalist Lily Bridge is on the road to employment with a local paper. Her task? Find out information about the Demonbane by whatever means necessary! Joined by Kuro Daijuji, private investigator, Lily's skills are put to the test when mad scientists, otherworldly women, and even Demonbane itself gets in the way!
While Demonbane does not share anything with Sky Girls in plot, it does retain a similar feel as far as mood and tone. Demonbane is definitely the more comedic of the two, though, and I enjoyed it considerably more as well.
