If you are a anime guy, then you probably have already watched Death Note. Modern day masterpiece Death note is written by Tsugumi Ohba and illustrated by Takeshi Obata. he story follows Light Yagami, a high school student who discovers a supernatural notebook from a Shinigami named Ryuk that grants its user the ability to kill anyone whose name and face he knows. The series centers around Light's attempts to create and rule a world "cleansed of evil" as "God" using the notebook, and the efforts of a detective known as L to stop him. Drama and suspense is so lit that you will complete the anime series within a day :D. I will not spoil much but the end is a sensation. The story portrays how a man loses his mind if granted power. Ryuk, shinigami is a perfect catalyst for the story although L is fan favorite. Anime is 37 episode long and interval of the series comes with a great twist. I know you are going to love the show.

One Punch Man is a story of a man who was a superhero wannabe, dream to be exact. s an ongoing Japanese superhero webcomic, which began publication in early 2009. Protagonist of the series is Saitama who is extremely powerful. He does not need a second punch to destroy his enemy. Literally he is the strongest superhero there is. Saitama is seemingly ordinary. He is bald and does not give appearance of cliche superheros.

An anime television adaptation by Madhouse aired in Japan between October and December 2015 which was internet shaker. The first season is short with only 12 episodes with some special episodes. It is worth your time so don't miss it. :D

Oh I cannot tell you how epic is Boku no hero academia. You gotta check it out for yourself. The world of Boku no hero academia is a world of superpowers. Almost 80% of newly born children are born with superpowers called 'quirk'. Izuku Midoriya (main character) is not lucky enough to be born with quirk as his friends, so he is a normal human being but has a big heart to help others. He wants to be a hero who never wants to lose to evil.

He then inherits power from a hero 'ALL MIGHT' who is also his idol. I personally recommend this series because it is the best hero anime i have watch recently.
