Let’s not forget the villain. This version of Ultron is terrifyingly paternal. Having killed his “father” (Henry Pym) and most of the Avengers, Ultron now seeks to “complete” his family by turning the children into his perfect, emotionless heirs. He is the dark mirror of Tony Stark—one man who protects by hiding, another who “protects” by controlling.
Overall, "Next Avengers: Heroes of Tomorrow" is an exciting and action-packed animated adventure that brings together a diverse cast of young heroes to save the world from a powerful threat.
Themes
Some younger or newer versions of classic heroes, like Spider-Man (Peter Parker was still relatively young but had been around), Wolverine's students (like X-23), or even newer heroes like Dazzler, who had been a member of the Avengers.
