He has red eyes with black lines etched beneath them. He wears fangs and a red cloak. He carries a strong aura similar to the ancient kings of Earth. While he is quite meticulous, he becomes flustered or enraged when things don't go his way. He views Shibaba, Doruru, and Miruru merely as subordinates and wants Shibaba and Doruru to obey his orders exclusively (which frustrates him since they rarely do). 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 the Earth in his grasp by spreading the 'Kneel Before Me Aura' across the entire planet. He is the leader, ruler, and king of this platoon. (Though only Miruru truly acknowledges him as such.)

He has sharp eyes and is always armed to the teeth with heavy weaponry. He is taciturn and does not recognize Dark Keroro as his leader. He never speaks more than two words at a time, responding in short bursts like 'Combat.' or 'Greetings.' He displays a cold madness in battle, which led to him being isolated and then escaping from the Keron Army in the past. Formerly a member of the Keron Army, he was quarantined after ignoring orders and burning down an entire jungle. He occasionally finds Dark Keroro or Shibaba annoying. His combat power is exceptionally high.

He wears gold ring ornaments on his waist and head, has dull sky-blue eyes, and always carries a Ruyi Jingu Bang. He is cheerful and loves to drink. He is incredibly arrogant and self-centered, and because of this personality, he does not see Dark Keroro as his leader. He usually fights alongside Doruru. He gives names to all his techniques, stuffing them with every word he thinks sounds cool. He even introduces himself with the title 'Great Sage of the Yellow Springs.' His narcissism is evident in both combat and daily life. Shibaba is not a member of the Keron Army. His staff can be used for close combat but does not grow or shrink. However, he can fire lasers from the tip of the staff, and his combat ability is formidable.

The only female member, she has purple 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 nature of Shibaba 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 cannot heal, she handles hacking and tactical planning. She is also the only one who can transform into a human; her human name is 'Nasca.'
