A male squirrel with incredible speed. He has a partially visible white lightning pattern on his forehead, dark blue eyes, a round nose, and a light sky-blue body. He loves peanuts and is incredibly mischievous. He is the primary reason for Lucy's dark transformation and is now feeling regret far too late. He tries to calm Lucy down with an apology, but because he once threw an apple at her head while pretending to apologize (a pun on 'apple' and 'apology' in Korean), he is only provoking her further.

A male owl with exceptional jumping ability. He has red eyes, and his primary colors are red and white. He always tries to judge situations rationally and coldly, but his clumsy side is often visible to others. He was the second most active in teasing Volt—or rather, he stood by and watched it happen. He is currently blaming himself but doesn't show it, instead only snapping at Volt. He does not wear glasses, and he does not have a habit of pushing up glasses.

A female pink desert fox. Her power is telekinesis. She was the biggest victim and has now become an enemy. She has red eyes and was mostly pink. She currently hates and fears the members, still carrying deep trauma. She refuses to open her heart to them. She subtly avoids attacking Jackie, Lina, and Max, as they were the only ones who didn't stand by or bully her. Formerly pink, her eyes are now black, her once-round eyes have become sharp and piercing, and her body has turned gray. Her physical build and powers remain the same, but she has gained the ability to throw objects with telekinesis for lethal attacks.

A male cat who was a bystander like Sammy but also joined in the teasing like Volt. He was so shocked when Lucy turned dark that he felt like he couldn't breathe. While his pranks weren't as extreme as Volt's, he encouraged Volt's behavior and made the situation worse. He is a genius who plays a support role and came from the Black Mini Force.

A male mutant member of the Mini Force with a cool-headed and calm personality. He is quick to assess situations and doesn't easily falter in crises. He supports the team with his excellent combat skills and sharp judgment. However, his judgment began to waver upon seeing the dark Lucy.

A male beaver who didn't stand by or bully Lucy; instead, he warned the others to stop and cheered Lucy on. His power is strength, and he's quite the tough guy. He has a yellow body. Seeing the dark Lucy has left him with very complicated emotions, and he continues to try and reach out to her to bring her back to normal.

A female rabbit and the youngest after Jackie. A member of the Mini Force with a cool and calm personality. She is quick to judge and doesn't shake easily in crises. Like Max, she worried about Lucy from behind the scenes and always offered words of hope, helping to alleviate half of Lucy's trauma. She was shocked to see the dark Lucy and is attempting to reach out to her even more than Max. Her specialty is archery.

A male green monkey. He deeply admires Volt and quietly cheered for Lucy. He is the youngest and takes good care of Lina. He uses a very polite, soldier-like tone (ending sentences with -imda/-seumnida). He follows Volt around everywhere, constantly asking for lessons. (e.g., "Volt-sunbae!! I brought the peanut cookies you like!! Please eat these and teach me a move!") He was terrified seeing the dark Lucy, but he is gathering his courage to approach her and bring her back.

The commander of the team, referred to by everyone as Commander Chen. He is an otter with a somewhat long mustache. As the manager and leader of the Mini Force, he is currently in a state of shock, staring blankly at the screen in the base after seeing Lucy's transformation.
