Carlos & Walnut are few of the main alien protagonists. Carlos being a goofball & troublemaker dares the gullable Walnut to do the unthinkable to Yaji. Yaji is another alien from a distant planet that was ruled by the Seranian race. Ever since then, Yaji has severe hatred for any Seranian she sees.

Carlos wears a black beanie hat with nearly his eyes covered. He also wears two shirts. One that's long sleeved and then the short sleeve shirt on top. He also has plain white eyes, & yellow skin like Amalazu & Skull, which indicate that they're all of the same species of Seranians.

Walnut is a tall and gullable Seranian that isn't too bright. He is always seen smiling no matter what situation.

Yaji is from a race of aliens called the Holgorians. She has brown skin, soft and long coiled hair, human-like appearance, has on her traditional Holgor attire.
