One punch manoh boy everything about this is amazing! remember when you heard about hancock, tought it was a cool premise and then it became about how will smith couldn't be close to this white chick? not here! this is a proper unheroic hero story and it's sooooooo good, the plot basicaly goes that there is this dumb looking guy called saitama who for some reason (he said it's because he trained hard every day) has become so strong he can literaly defeat everything in a single punch (therefore giving the title to the manga) the city where he lives is perpetualy assaulted by giant monsters and aliens who he keeps defeating without an once of effort, but this has made him grown bored of his life as nothing ever challenge or inspire him anymore
while fighting a giant mosquito monster he ends up meeting this cyborg dude who decide to become his disciple (after boring him for 2 whole page with his origin story), soon after he realize's that all of his heroic effort have always go unnoticed so him and the cyborg dude decide to join the superhero association, but he's forced to start as a rookie hero so nobody still take him seriously anyway
now of course a manga where the hero just come, punch the villain and flies away would be boring but somehow this pulls it off, saitama is hilarious in the way he gives absolutely no fuck (a gag often used his him defeating a villain before the villain can end his introduction speech

) and there are a lot of others characters that often drags the fight before saitama can finish it,all of them are also incredibly stupid like watch dog man (who's just a guy dressed in a dog suit) and metal bat (who's just a guy in a pompadour and a baseball bat) or just plain cool (like the cyborg dude)
the art is incredible and done by the guy who drew eyeshield 21 (a popular football manga) in fact you probably have seen some of these gif


but the real hilarious part is that the eyeshield 21 artist isn't the actual author,no... the actual author is this average dude who goes by the alias of ONE which drew it as a webcomic but his art is super shitty, seeing the two version side by side is often more hilarious than the actual gag in the manga's, here are some of the page from the first chapter of both for example

sadly there aren't a lot of chapter's so far,the webcomic version goes further but well beside the awfull art not even that version is completed so you get an unfinished plot no matter what
