If you liked the One Piece anime, the Anime-Planet community thinks you'd like:
The future of humanity is in peril, as they are confronted with the threat of an intergalactic clash with a warrior-like alien race, and the only one who can save them is... Captain Tylor?! Join a crew of misfits and rejects including an alcoholic doctor, a gorgeous nurse, an anal-retentive commander and a bunch of really stupid marines as they try to make it out in space and to discover whether their captain is a misunderstood genius or a total moron like he seems to be.
Leadership is a very difficult thing. Someone says you can’t learn it but only gain from God. For Luffy and Tylor it's absolutely true. Main screen time they acting like fools without realizing what’s really going on, but when time comes they somehow managing to turn everything for their own benefit. Two desperate heaven-born captains definitely put these series together.
If One Piece’s length and Captain Tylor’s release date doesn’t scary you go ahead and watch them. You won’t be disappointed because a great comedy is a one more reason to unite these series.
Sumimura Yoshimori is a Kekkaishi – an inheritor of the power to battle demons, using barriers called kekkai. His family is charged with protecting the grounds of Karasumori high school, a building which magnifies the power of demons who enter it. Helping him are his spirit-wolf companion Madarao, and next door-neighbor Yukimura Tokine, the daughter of a rival clan. Years ago, Tokine was injured protecting Yoshimori, and now he is determined to become strong enough to keep her from being hurt again. Of course, he'd rather bake his exquisite cakes than have to fight demons at all, but fate has something else in store! As a shadowy demon organization moves to steal Karasumori's power, can Yoshimori overcome legions of demons, a centuries-old family rivalry, and a grandfather who just can't understand his love for baking?
Action, comedy, amazing characters. Each of these anime have this and more. Both Kakkaishi and One Piece drip with a large cast of enjoyable characters who will entertain you for hours. Fighting to protect the ones you love? They both address just that. If you like one you will like the other.
Keitaro Urashima is somewhat of a failure. In order to fulfill a promise he made to a girl fifteen years ago, he has tried time and again to get into Tokyo U but has never managed to pass the exam. However, fate smiles upon him and he ends up working for his aunt, managing an all-girls dorm! Living with the feral Kaolla, the timid Shinobu, the sake-loving Mitsune, the blade mistress Motoko and the punch-happy Naru, can Keitaro keep his focus and keep his promise? And will he ever end up meeting that girl from his past?
Satoshi and Arumi have been friends since early childhood, but now Arumi's family is moving to Hokkaido, deeply upsetting her long-time friend. However, when Arumi's grandfather accidentally breaks the pelican statue atop his restaurant, the duo find their world turned upside down and not quite as they left it. From a fairy tale kingdom, to kung fu China, to the prehistoric age and everything in between, Arumi and Satoshi can't quite seem to figure out where they are, or better yet, how they can manage to get home to their own Abenobashi Shoutengai!
Got a craving for some ridiculously humorous fantasy? Travelling to worlds you've only ever dreamed about has never been as easy as watching anime before. Both have those quirky bits that just pop out and capture your heart while having moments that lure you in with the "I need to know whats going to happen." Both are definatly adventures that need to be had.
The soul of the demon Mouryou has been freed, and with it his ambition to take over the world and create a "Thousand Year Kingdom." However, he will first have to recover his body from where it was sealed by the priestess Miroku. The only threat to his plans is Miroku’s daughter Shion, the only one with the power to stop him – and it will be up to Naruto, Sakura, Lee and Neji to escort her safely to once more seal Mouryou's soul. However, things won't be easy for Naruto and the gang: Mouryou has control over an unstoppable ghost army and has sent four ninjas to kill Shion; even more alarming is Shion’s newest vision of an impending death… which involves Naruto himself.
Luffy is pretty much Naruto in a pirate suit with a flag.. Except maybe alittle more clueless and loves meat awhole lot more then noodles. Seriously though, Naruto has his dream to become Hokage. Luffy has his dream of becoming the "Pirate King". Both are the highest titles one can obtain in there respective "Career Choices". Overcoming numerous challenges and obstacles along the way, winning the hearts of friends and people alike without ever losing a shred of their aloofness. The way I see it, I keep on bouncing between Naruto epi's and One Piece epi's. The way my favoritism wavers the age old question may never be answered... "Who would win, Pirates or Ninja?"
