don't watch the Ichigo 100% anime its god awful read the manga instead although you will still be disappointed when you finish reading it
and iv'e read through this thread and i'm shocked how terrible some of the suggestions are i mean black lagoon seriously other than both having pirates how the hell are they similar ,some people also seem to think just because two series a both shonen there similar witch is completely untrue.
true fully there really isn't much like one piece Fairy tail is like one piece executed poorly ,Soul eater mixes good characters with humor and fights but still difrent from one piece ,Gurren lagann has crazy characters and fights with good character development and the same sense of fun as Onepiece and theres the obvious dragonball but really there nothing quite like one piece
but you could always just try another Genre
I believe it doesn't mean it has to be similar to One Piece. Of course originality in story should always be a priority of an author. Perhaps he/she meant to ask any other series that will give the same level of entertainment as One Piece? Now it depends on what you enjoy in One Piece. But he/she specifically mentioned he/she enjoys funny scenes the most so these series came to mind.
Now I realized how long this thread has been lol. But there are plenty of funny animes that are not under OP's genre but gives me the same entertainment coz it's just pure funny and fun to watch. But haven't found any thing like One Piece in terms of story, characters and world. I have yet to try Gintama… but it seems so episodic that it turns me off as I love to watch a series with a bigger plot especially if it's a series that has numerous episodes (beyond 50) ... Soul Eater, I havent seen so maybe I should try it.
Anyways, I look forward to suggestions! XD
I've tried Reborn, I've seen Naruto and Bleach (They started good, in fact I saw them prior to seeing One Piece... but they just can't keep the quality) ... Other mangas I'm reserving and waiting for their animes. XD
