If you liked the Bubblegum Crisis Tokyo 2040 anime, the Anime-Planet community thinks you'd like:
A mysterious new hacker known only as the Puppet Master threatens to create chaos, erasing and rewriting the memories of his victims: humans who have cast away their physical body to become cyborgs. Is he an evil genius, or could he signal the beginning of a new age in the relationship between man and machine?
In the present, Japan is under assault by murderous creatures known as Aragami whose origin and purpose remain unknown. The fate of Japan and the world itself lies with one young woman named Momiji who bears the burden of the Kushinada -- the one who must be sacrificed to silence the Aragami forever. With the help of Mamoru Kusanagi (a human and Aragami hybrid), and an agency filled with firepower-toting bodyguards, Momiji must use her Aragami-sensing powers to help save mankind; but will she ultimately have to lose her own life to save the lives of so many others?
The idea of both Bubblegum Crisis and Blue Seed is the same, but instead of giant mutating robots taking over the city, you have a bunch of giant mutating plants and animals. Both of these have very good action too. If you liked one, you are sure to like the other.
Aya, Omi, Ken and Yoji are four seemingly normal high school boys, who make up an elite assassin group known only as Weiss. The hits involve taking out corporate businessmen and corrupt politicians; however, trouble arises during a routine job, when Weiss clashes with a rival gang of assassins, Schwarz. With Schwarz in the way, they will reach the limits of their elite skills while trying to defeat their ultimate target: the Takatori family...
Hazama is a private detective, who becomes fatally wounded in a run-of-the-mill case. In order to survive, Hazama is tranformed into the legendary cyborg 8Man -- to put an end to the cybernetically-enhanced criminals' wave of crime. But as the death count increases, Hazama soon begins to question how much of his real self is left, and if the emotionless 8Man he becomes is really in control...
Following the disaster wrought upon the world by a mysterious being called ‘Akira’, Neo Tokyo is now in social and economic turmoil. In such a decaying city, feisty Kaneda and his shy friend Tetsuo survive by running around in a biker gang, chasing local rivals and generally evading the police. Everything changes, however, when Tetsuo crashes into a strange-looking boy during a bike chase and the military ends up taking him away. When he eventually returns to his friends, he’s no longer the same weak little boy they always knew – in fact, a military experiment has turned him into something beyond human imagination. While the military is intent on reclaiming its specimen at any cost, Tetsuo is sick of being bullied around and is about to show everyone, including his friend Kaneda, exactly who is boss.
Akira is a long movie, Bubblegum is a series; both are highly futuristic with lasers and explosions.
More importantly, the stories are complicated and convoluted with the characters being very slightly more important than the action. At points both are confusing, but both are quality works that many have enjoyed thoroughly.
