The story centers on the Clade family saving the pando plant from blight in a living subterranean world, but explicitly features Ethan Clade (voiced by Jaboukie Young-White) as Disney Animation's first openly gay main character with a visible crush on boy Caspian (Karan Soni), including family acceptance scenes that drew bans in over a dozen countries. The interracial Clade family includes Black pilot Meridian (Gabrielle Union) and mixed-race Ethan, alongside Asian commander Callisto Mal (Lucy Liu), framed by directors Don Hall and Qui Nguyen as essential representation to address past Disney shortcomings.

Environmental messaging drives the core conflict, portraying exploitation of the world as destructive and promoting harmony over traditional exploration or resource use. Audience reception showed clear divides, with box office failure ($11.9M opening) widely linked to the LGBTQ subplot and diversity focus, including 'go woke go broke' critiques and lower audience scores versus critics. These elements extend beyond organic adventure tropes into intentional inclusion mandates that shape character arcs and marketing.
