I've only see the first 29 episodes so I have admittedly fallen behind and its currently in my "on hold" list. People have described this series as Pokemon meets Avengers but I see it more so as Digimon meets Avengers.
Similarly to Digimon Adventure, a group of young people are paired off with a different Avenger character in an adventure battle series where the goal is collecting stuff. Like in Digimon, each respective Avenger can only fight when their partner "summons" them through stock transformation sequences. Each kid has a personality that nicely contrasts the Avenger they are paired with, allowing for character growth. For example, The Hulk is paired with a nerdy, introverted kid while Captain America is paired with a teenage rebel.
The biggest attraction to this series for me is seeing Marvel Comics characters in an anime series. As a comics nerd, I enjoy seeing how Japanese creators visualize and give life to US creations. From what I've seen, they have done a great job at characterizing the Marvel characters as they should be.
If you aren't a Marvel comics fan or a fan of kids shonen adventure anime, there's pretty much no reason for you to watch this.
