Cyclizar is a green reptilian Pokémon resembling a lizard. Its head is mostly black, with a green coloration between its casque and lower jaw, along with orange circular cheeks. Its neck, paw pads, and tail are also black; the latter has a white tip. Its rear has a covering resembling a motorcycle seat, located at the base of its tail. On its throat is a black sac with white inner coloring, resembling a rubber tire. According to Jacq, Cyclizar has three forms. First, Cyclizar's basic form where it walks on all four legs. Second, the battle form where it stands on its hind legs in order to battle. Finally, the ride form which it assumes when humans ride on it. When Cyclizar is being ridden on, it puffs up its throat sac and curls its tail, making the appearance of wheels.
Cyclizar has a mild temperament. It has been kept by humans and used for transport since ancient times, with depictions of this behavior found in murals dating back 10,000 years ago. This relationship appears to be mutualistic, since the warmth of Cyclizar's rider helps it avoid getting cold, along with lifting its spirit. When carrying a human, Cyclizar can reach a speed of over 70 mph (120 km/h). Cyclizar maintains its balance and absorbs shock while running by using its hard head and thick yet supple tail. It also uses its head and tail to attack during battles. Both Koraidon and Miraidon share a resemblance to Cyclizar, a detail noted by several NPCs in the game and their own Pokédex entries; it is later confirmed that they are ancient and futuristic versions of Cyclizar, respectively.
Cyclizar may be based on lizards, most notably the anole and the genera Sitana and Sarada — the latter two are collectively known as fan-throated lizards. It also has traits from other lizard species: its foot pads resemble those of the gecko, its tail resembles the prehensile tail of the chameleon, and its casque appears to be based on that of the chameleon or the helmeted lizards. Some elements of its design appear to be based on parts of a motorcycle: its casque resembles both a motorcycle windshield and a helmet, its cheeks are similar to turn signal lights, its rear looks like a motorcycle seat, and the protrusion on its chest together with its tail resemble rubber tires, the latter especially when curled.
Conceptually, Cyclizar seems to be designed to function like a "missing link" between Koraidon and Miraidon, and its anatomy apparently reflect an intermediate state between those two, for example, Koraidon's second and third digits are separated but connected by a skin membrane, whereas Cyclizar's seem to be partially fused, and in Miraidon's case, they are fully fused. Cyclizar and Miraidon share an elongated crest, subtympanic shields, beak-like snouts and lack feathers, meanwhile, Cyclizar and Koraidon share black tire-like scales on their tail and chest region, black pads on the inner side of their paws, and lack exposed claws.
Cyclizar may be a combination of cycle and lizard.
Mototokage may be a combination of moto (Spanish, Italian and Portuguese for motorcycle) and 蜥蜴 tokage (lizard).
