Kyu has always been interested in solving mysteries. After assisting in a murder case, he earns the opportunity to take the entrance exam for the Dan Detective School (DDS), a famous detective school established by the equally famous detective, Dan Morihiko! DDS is trusted implicitly by the police and receives their absolute cooperation in all matters, and its students are often able to crack even the most difficult cases. Can Kyu, along with fellow classmates Megumi, Kintarou, Kazuma and Ryu, meet the demands of the school and the crimes that cross their paths?
These series may not seem similar at first glance, due to one being a detective mystery and the other about superheroes. However, there are similarities that go outside the genre. The genres in themselves are not that different from each other after giving it some thought, both featuring gifted individuals dealing with criminals and bringing about justice. They both have fairly large ensemble casts, and while the episodes focus on two main characters, there are episodes that deal with each member of that main ensemble. Detective Academy Q isn't exactly a competition in the way that Tiger & Bunny is, but there is a spirit of competition with the main characters, not to mention the rival class from Detective Academy Q that tries to 'outsolve' the protagonists. While most episodes of both series deal with different crimes that are wrapped up in a matter of episodes, they both have a larger mystery that is ever present throughout the series.
Humanity is on the brink of extinction after a devastating space war. Vicious packs of mercenaries known as "Vultures" comb Earth's remains for weapons, supplies, or anything else to give them power. Young Garrod Ran, an orphan of the war, is hired to rescue a kidnapped girl. But in time, he discovers that his target is a powerful enhanced human called a "Newtype" who is set to be the target of terrible and inhumane experiments. Now, Garrod and his new friends must escape, while trying to save the human race from repeating its mistakes yet again.
It's the 1930s, and Mafia groups fight for supremacy in American cities. Young Firo joins the secretive Camorra group; a meek street boy, Jacuzzi, finds himself the leader of a gang of thugs; an alchemist is producing a liquor of immortality, and a homunculus tries to retrieve it; and upbeat thieves Isaac and Miria head to New York after failing to strike gold in California. They ride the novel train, the Flying Pussyfoot, across the continent. However they find themselves embroiled in a ruckus caused by gangs, terrorists, serial killers, and others as multiple stories intertwine and unfold on this fateful ride. All are haunted and hunted by the legendary Rail Tracer...
Warning: Baccano! is a VERY bloody series, so if violence bothers you, disregard this recommendation! That said, both series feature entertaining characters, great action scenes and a fantastic art style (with a particularly good mix of CGI and traditional animation). Also, a key character in Baccano! is played by Barnaby's seiyuu. I wouldn't say either series leads me to think particularly deep thoughts, but they both get my blood pumping and really entertain me.
Gonzo does it again with this action-packed mecha comedy. She's an ordinary high school girl. He's a counterterror agent assigned to protect her from those who would steal the information locked in her mind. OK, so she's not so normal after all. Armored Slave battles and lovers' spats abound as Sousuke and his comrades try to track down the mysterious Gauln before it's too late.
Both are colorful action series with memorable characters and great action, as well as a lead that seems silly but is far more capable than you first assume. They also have a parent/child relationship that is an important part of the backstory. Star Driver is more focused on typical tropes of anime high school characters (including a love triangle) and has a fair amount of sexual innuendo, while Tiger & Bunny focuses on adult characters (who mostly take a backseat in Star Driver), but I think these two are similar enough in tone to be a worthy recommendation.
