In a post-apocalyptic world ravaged by earthquakes, grotesque monsters and powerful demons run rampant through the streets of New Tokyo. Only a select few people have been trained in the techniques necessary to defeat these creatures. Brothers Kakugo and Harara Hagakure not only possess the skills, they also harbor the power of the Zero Armor containing the souls of thousands of warriors. Separated from his brother, Kakugo roams the land fighting in order to restore some sort of peace and safety to mankind. However, he finds these monstrosities to be merely pawns to a much larger adversary from his past, who may prove to be his most dangerous opponent of all.
Imagine a world devastated by nuclear war, where the strong oppress the weak and strength is the one thing that will ensure survival. A world where even close friends can betray you for power, a lesson that Ken, the Fist of The North Star, learns when he is nearly killed by his closest friend and left for dead. He's not an easy man to get rid of, and he returns - very angry.
I believe I heard "Omae wa mo shindeiru" (You are already dead) in Apocalypse Zero the other day. Joking aside, aside from the fact that there are battle suits involved in AZ, the similarities are pretty much striking. Post apocalyptic world and martial arts with sure kill techniques that are used, both main characters protect what little is left of honor and justice.
If you like Kakugo no Susume you might like Hokuto no Ken (and vice versa) because both of them deal with the same type of problem. It's a post apocalyptic world where violence rules. The only difference is that in Hokuto no Ken the enemies are humans, while in Kakugo no Susume they are mutants.
Both anime have a "suit of armor" that takes over whoever wears it. Depending on how willed the person is they can control it or be controlled by the suit. Crazy action, violence, and weird characters a plenty. Both take place in worlds where mankind isn't doing so well and struggling to survive. If you liked one i highly suggest you check out the other.
Throughout the galaxy, two villains destroy and pillage anything in their path. Their names are Cross and Chaos, and they are ready to invade their next target: Earth. The only defense against these warriors are the Iczelions, a fusion of young girls, and Iczels, sentient body armor. Nagisa is a typical high school girl who is about to become the next Iczelion against her will, to defend the planet and save the human race! But not if she has anything to say about it...
Both anime have both bad guys being either a strange brother and sister combo (Iczer) or a very angry sister of the hero (Apocalypse Zero) that want nothing more than to beat the crap out of the good people that stand in the way of their goals. Apocalypse Zero has much more gore and shock value to their scenes than Iczer but both have similar story pacing and confusing characters. If you liked one check out the other.
Shou Fukamachi is just an average high school student,until one afternoon, Sho and his friend Tetsuro stumble upon what looks to be a landmine, which Sho accidentally activates. Instead of attacking and killing him, it grants him control of the Guyver, a powerful biological armor, which the evil corporation Chronos wants to take at any cost, even if it means killing Shou and his friends.
At their simplest, Guyver and Apocalypse Zero are anime about a guy in a living power suit that fights monsters and opposes an evil organization.
Guyver does away with the over the top gore of apocalypse zero and instead comes up with more story and character development. Regardless, if you enjoyed the battles in Apocalypse Zero, you are sure to enjoy Guyver.
