Adolescents Assemble!

From the introduction:

A team of brand-new young superheroes are meeting up to discuss how they’re going to handle their very first team challenge. They are experiencing changes in their bodies as their powers develop, and some of these come with challenging side-effects. They also each have their own particular emotional needs. Their task is to help each other out and work out how to meet their team’s needs while fulfilling their first mission. Finally, they celebrate their growth by designing their costumes and choosing a superhero name that reflects their contribution to the team!
