Physical Appearance

Martin is a young man of average height; he usually wears hiking boots, khaki shorts, and a blue jacket with the zipper zipped almost all the way down and black stripes running across the sides with the sleeves rolled up, along with his Creature Power Suit. He has blue eyes, tan skin, and sandy blond hair, with the cowlick showing. In Polar Bears Don't Dance, while adventuring in the Arctic, he wore a blue jacket, jeans, and boots, along with his Creature Power Suit. He is taller than his younger brother, Chris.

Martin's favorite color is blue.


Like his brother, Martin is playful, childish, comedic, and simply loves creatures. Due to this, he is often seen as the "jokester" of the group, always cracking up a smile. On the other hand, he is impulsive, overly optimistic, and while usually prepared for any situation, he sometimes isn't. He likes to taking risks, and he is easily distracted, sometimes forgetting that he is on a mission. Martin can be impatient, as seen in Bandito: The Black-Footed Ferret, where Aviva told him not to touch the new invention, the Stone Digger, while the others told him to wait until morning, and he uses it anyways. He tries to be a "big brother" and "save" Chris from "danger". Martin loves to get into the mind of creatures, and often ifentifies with them, specifically when in the use of a Creature Power Suit. However, he does know when to be serious, and he makes a good teammate. He also knows when to put a creature adventure aside, as shown in "Fossa Palooza", when the team had to go home for Mother's Day. He dearly loves his fellow creatures, and enjoys giving them names, especially the younger ones.


Martin works with his brother, Chris, and their friends to learn about animals and save them when necessary. He uses his creature knowledge, swimming skills, and creature powers to save the creature world. He has extensive knowledge of various creatures, as he is a professional zoologist. He is an exceptional swimmer; he also knows how to water ski, snowboard, and "manta board".
