Well, since the heroes in the animes which I've seen are very strong, suggest me animes where the hero is strong. Comedy would be an added bonus, but not a necessity.
Naruto - Good show if you avoid the fillers. Nice range of fleshed out characters and story has depth too.
Bleach - Kickass action but show got cancelled, still worth watching thg.
One Piece - Colorful characters, not for everyone and has over 500 eps and counting !
Fairy Tail - Has a good combo of action and comedy, one of the recent fighting animes that is still airing and worth watching.
DragonBall Super - Season 1 was a re-telling of the last two movies, still worth a watch. Season 2 is gonna be a battle between the universes, must for a DBZ fan imo.
Notable mentions - Samurai Champloo, Soul Eater, Claymore and the more recent Kill la Kill and Akame Ga Kill.
Before you decide to watch any of the above do check out these popular animes from the last 2 years, they also have fewer episodes so you'll get done with em fast.
Hataraku Maou Sama - Funniest show last season and only 13 eps long, Lucifer escapes to earth and has to work at Mcdonalds, what else is there to say.
Sword Art Online - I liked it because it's the only amount of cheese I can tolerate in any media. It feels like just any other Shounen anime until episode 12 of season 1, you will either love it or hate it after this point.
Attack on Titan - Everyone is vulnerable and prone to death, starts off a bit slow but keeps you hooked till the end, season 2 starts soon.
No Game No Life - Not fighting per se but it ends in 13 eps and is definitely interesting.
