The kings residing in the castle of the Lucky Mercenary world. The one in red on the left is Jawang, and the one in blue on the right is Uwang. Both are bald. They are quite cowardly and spend their time recruiting heroes or assigning roles within the castle.

A cat and a mage. She lives in a house near Uwang Jawang's castle, filled with magic books and altars. She used her magic to bring the user here from the zombie apocalypse. She serves as a supporter who restores mana for the team. She is raising a dragon (but the dragon is so disobedient that she often hits him with her magic staff...).

A brown-furred, incredibly muscular figure. Because of his name, he's often teased with nicknames like Sibamba or Babamba, making him a bit of a punching bag. He's responsible for repairing the castle (though he usually dumps the work on the Paladin while he plays with Iron Meow). He loves Iron Meow. He is bald and loves cute animals.

A handsome Taoist with silky blue hair parted down the middle. He usually has his eyes closed, sleeps a lot, and travels on a cloud. He carries a fan that summons wind and speaks with a slight dialect. While his expressions are hard to read, he occasionally smiles, giving him a subtle charm. Unlike other diligent and urgent Taoists, he is peaceful and laid-back.

A red-haired character armed with daggers. Surprisingly cute. He occasionally earns coins when he attacks. He is a master of theft.

A blue-haired warrior whose weapon is a long sword. He has a healthy body and mind thanks to his upright habits. He is the ultimate punching bag... During the mercenary interview, he was assigned to castle construction, but instead of helping, Bamba makes him do all the work.

A white-haired man. Very intelligent. At the Pulse Lab, he rarely does actual research and mostly spends his time caring for and playing with Iron Meow. His main weapon is a pulse generator. He recently rescued a cat collapsed in front of his lab—that cat was Iron Meow (he is the one who saved him and gave him the suit). He is kind-hearted.

A cat. Usually, he just carries the hand part of an Iron Man suit, but as he upgrades, he wears the full suit, and eventually, he boards a Hulkbuster machine. If he sees a button, he presses it. Abandoned by his mother as a kitten, he collapsed from exhaustion before being rescued by Dr. Pulse. He is Bamba's favorite animal.

A giant green member of the Blob race. His most frequent phrase is "Broooob?" and he can only say "Blob Blob." He is a demon who can eat enemies; the more he eats, the larger he grows. He is cute.

The Meowgician's... son? He gets so frustrated by Uwang Jawang's antics that he loses his temper, only for the Meowgician to hit him to calm him down (poor Dragon). After a few hits, he cries out "I hate you, Mom!!" and leaves in a huff (only to return to her house within 30 minutes).
