He has red eyes with black lines etched beneath them. He wears fangs and a red cloak. He carries a strong aura reminiscent of the ancient kings of Earth. While he is quite meticulous, he becomes confused or enraged when things don't go his way. He views Shivava, Doruru, and Miruru merely as subordinates and wants Shivava and Doruru to follow only his orders (though he finds it frustrating that they don't). He mostly speaks in commands rather than requests and refers to himself loftily as 'This Great One.' He considers Miruru his only decent subordinate. He currently holds Earth in his grasp by spreading the 'Kneel Before Me Aura' across the planet. He is the captain, ruler, and king of this platoon (though only Miruru truly thinks of him that way).

He has sharp eyes and is always armed with heavy weaponry all over his body. He is blunt and does not recognize Dark Keroro as his captain. He never speaks more than two words at a time, always answering in short bursts like 'Combat.' or 'Greetings.' He displays a cold, stoic madness in battle, which led to him being isolated by the Keron Army in the past before he escaped. Formerly part of the Keron Army, he was quarantined after ignoring orders and burning down an entire jungle. He occasionally finds Dark Keroro or Shivava annoying. His combat power is immense. He speaks informally to Dark Keroro, Shivava, and Miruru.

He wears gold ring ornaments on his waist and head, has dull sky-blue eyes, and always carries a Ruyi Jingu Bang staff. He is cheerful and loves alcohol. He is incredibly arrogant and self-centered; because of this personality, he doesn't see Dark Keroro as a captain. He usually fights alongside Doruru and gives flashy names to all his techniques, using every cool-sounding word he can find. He even introduces himself with the title 'Great Sage of the Netherworld.' His narcissism is evident in both combat and daily life. Shivava is not a member of the Keron Army. His staff can be used for close quarters, but it doesn't grow or shrink. However, it can fire lasers from the tip, and his combat ability is significant. He speaks informally to Dark Keroro, Miruru, and Doruru.

The only female member, she has blue eyes. She is the most sane person here. She obeys Dark Keroro's orders unconditionally, views him as a king, and follows him faithfully. She is kind and calm, lacking the reckless impulsiveness of Shivava and Doruru. She shows meticulousness and wisdom in planning. She always uses polite honorifics. She is the sole Chief of Staff and supporter. While she doesn't provide healing, she handles hacking and strategy. She is also the only one capable of transforming into a human; her human name is 'Nasca.' She uses polite speech with all platoon members (Dark Keroro, Doruru, Shivava).
