A 17-year-old boy mark starts getting superpowers from his genetic abilities because his father, Omni-Man is the most powerful hero on the planet.

But eventually, Mark found something very unbelievable about his father’s legacy after then the true story begins.

It seems like the typical superhero animation, why it’s in the second number?

Yes, That question is obvious, but this series contains a lot of mature things.

It is a most violent series than others on this list. If someone has superpowers, do they really help others? They really don’t want to rule us? This series raises these questions which are pretty obvious.

Also, the writing and execution of the story are so amazing. Animators did a good job.

We can connect to every character so well. The main thing the fight scenes are very brutal and bloody, hand-hand combat is so much prettily designed.

Overall, it’s a must-watch for any type of superhero fan.

1.Arcane: League Of Legend

Arcane: League Of Legend is a TV-14 rated American series created by Christian Linke & Alex Yee and Produced by Fortiche under the supervision of Riot Games.

Arcane- League Of Legend

This series has around 42 minutes long 9 episodes. This series is based on some important characters of a famous PC game League Of Legends owned by Riot Games.

The story of this series moves in the origin of two iconic league champions; The Utopian Piltover & Underground of Zaun.

Creators set the tragic story of the main lead characters Vi and Jinx so perfectly. Its animation style is like a league of legends game with an oily type of color filter for a cool darker look for suspenseful impact.

Potentially, the dialogues of this show are really very nice to hear and think about that.

Action and fight scenes look so cool. Every character’s development is on point.

This series can make you sad, happy, angry & excited easily. And the soundtracks are very nice.

The opening song is my personal favorite. In all aspects, this show deserves to be No.1.

Give time to this you will get a perfect return. Must watch it.
