Robonimal Island

• Pan-Taron (パン･タロン) - Pilot of the Panda-Z.
• Dr. Panji (ドクター･パンジィ, Dokutā Panjī) - Taron's grandfather and the director of the laboratory. He is a researcher at the mysterious "Super P-Z" and an authority on Robonimal engineering. He created the Panda-Z along with Taron's father (who left one day years ago and never returned). But outside of that, he is just a kind grandfather, who loves his grandson very much.
• Rabinna (ラビンナ) - A pink robot rabbit with angel wings and a white nurse's outfit. She dreams of becoming a great nurse someday. She has a cheerful, kind personality and also has a strong sense of responsibility.
• Denwan (デンワン) - He is something of a leader in Taron's group of friends. Denwan is dependable, but sometimes, he gets ahead of himself and ends up failing. His dream is to become a great public Denwan someday. (Denwa (電話) is Japanese for "telephone" and Wanwan is the sound a dog makes so he is basically a telephone dog.) He is, however, a pay phone, requiring others to pay him to make an outgoing call. Also, his dial only has seven digits.
• Eteckee (エテッキー, Etekkī) - He is a brilliant and talented scholar. Sometimes, he can be timid and a bit of a scaredy-cat, but he dreams of becoming a researcher at the Panda-Z Lab someday. His name seems to be a pun on "techie" and "monkey", and is a yellow robot monkey.
• Zoutank (ゾウタンク, Zoutanku) - A green robot that is a cross between an elephant and a tank, with a cannon for a trunk. (Zō (象) is Japanese for "elephant".) It seems to be an independent character, rather than merely a vehicle. However, it's large enough for other Robonimals to ride in.
• Kuma Rescue Team (K.Rチーム（くま、れすきゅーチーム）, Kuma, Resukyū ̄Chīmu, lit. Bear Rescue Team) - The rescue professionals at the Panda-Z lab:

• Medical Bear (メディカルベアー, Medikaru Beā) - A white bear with red rescue flasher ears and a doctor's speculum (mirror headband). Rabinna is his nurse.
• Fire Bear (ファイヤーベアー, Faiyā Beā) - Basically the fire fighter of the group.
• Rescue Bears (レスキューベアー, Resukyū Beā) - A pair of nearly identical bear robots, with "01" or "02" on their ears. They're litter-bearers, among other tasks.

• Mechanic Team (メカニックチーム, Mekanikku Chīmu) - Consisting of Hamu Ichiro (ハムーイチロー, Hamū Ichirō) and Hamu Jiro (ハムージロー, Hamū Jirō), they are the mechanical team at the lab. They are both incredible mechanics and Panda-Z's feats are often made possible thanks to these two. They pilot the Ham Gears, giant robots that let them repair Panda-Z at its own scale, as well as carry a damaged Panda-Z off the battlefield. There seems to be no relation between the noncombatant Ham Gears and Dr. Jangarly's Black Ham Gear.

Warunimals

• Skullpander (スカルパンダー, Sukarupandā) - Leader of the Warunimals, what's beneath his cloak is a source of mystery to his own generals. He is spooky and mysterious and rarely seems to do anything, generally staying in his cloud-wreathed island headquarters.
• Mougyu (モウギュウ, Mougyuu) - A Warunimal general with a cow-like appearance. Mougyu is probably Taron's most frequent opponent. He is often cheated of victory because his remote control breaks, or he is injured when he gets dragged along behind it on the remote's cable. Mougyu's giant robot Moujumbo (モウジャンボー, Moujanbō) uses a large hammer.
• Doctor Jangarly (ドクタージャンガーリ, Dokutā Jangāri) - A robo-hamster with a mustache and a clear dome skull that shows his computer brain. When he smokes, the smoke fills his dome and he shorts out. His giant robot Black Ham Gear (ブラックハムギアー, Burakku Hamu Giā) is not completed until the end of the series, and he frequently threatens dire vengeance once it is ready.
• Wolgar (ウルフガー, Urufugā) - A robot wolf who is perhaps a little too domesticated, sometimes playing fetch when he should be fighting. Normally light gray, he turns red under a full moon. His giant wolf robot Wolgaoh (ウルガオー, Urugaō) has a set of "bone nunchaku".
• Rubyraby (ルビィラビィ, Rubīrabī) - A rabbit-princess with adult proportions (as opposed to the child-body proportions of everyone else). Her giant robot Rubyrabeauty (ルビィラビューティ, Rubīrabyūti) occasionally demonstrates the ability to act on its own, and at one point seems to fall in love with Panda-Z.
• Kokekkou (コケッコウー, Kokekkoū) - A giant robotic rooster, apparently an unpiloted Warunimal asset. It can launch egg bombs, fly, and is assisted by smaller flying robot roosters. Its name is derived from the sound of a rooster's crowing.
• Warunimal Soldier (ワルニマル兵, Warunimaru-hei) - Identical masked minions who wear four color schemes to denote which general they follow: yellow for Mougyu, black for Jangarly, light gray for Wolgar, and pink for Rubyraby. They do not seem to like their generals and sometimes argue amongst each other which group has it the worst.
• Bokkuma (ボックマ) - A box on legs with panda features that serves as Rubiraby's pet.
