I just rewatched the show and season 1 had nothing to do with space immigrants, unless you count the cliffhanger ending where Mo's Oasis gets teleported into space.
Season 1 was the best overall because it has the strongest theme. Kid wants to be a superhero because heroes are cool and live exciting lives, and season 1 is about Kid learning what being a hero is really supposed to be. The main antagonist of the first season shares Kid's initial improper notions of what heroism is, caring more about stylishly fighting off whatever aliens show up rather than trying to understand them. Allegorically, when Kid finally understands what it means to be a hero, he unlocks the full power of his cosmic stone, which he was unable to properly wield because of his own childlike, selfish desire, and he finally becomes the hero he wished to be.
By contrast, season 2 is Jo-focused and Kid's arc is basically a more shallow version of his season 1 arc where he 1. learns to focus on how he can contribute instead of just wishing he still had his awesome s1 powers and 2. learns to work better with Jo. Since the focus on Jo, her arc in s2 is about her struggling to become an effective leader. She sinks to her lowest when she foresakes her team and gets backstabbed, and in the end all of her leadership training is basically for nothing because her brilliant plan is, "everyone just grab whatever stones you want and go nuts," until Kid helps her make a better plan on the fly. I guess they were going for a, "Jo already knew what the right thing to do was and just needed to learn to be more confident," kind of arc, but it kind of falls flat.
S3 is about being honest with people and not giving up hope and also remember that heroism involves sacrifice... or something I guess. It's all over the place. There's no consistent throughline like there was in the first two seasons. If any season needed a redo, it's s3. It feels underbaked.
