The Wild Liger is a small Zoid with an open-air cockpit. Compared to other Zoids in the Zoids: Wild series, it is an M-sized Zoid.
The Wild Liger is piloted by Arashi, the main character of Zoids: Wild. Known as a legendary Lion-Type Zoid, the Wild Liger initially escaped from the Death Metal Empire after defeating 100 Zoids. Team Supreme searched for it for 10 days, before meeting Arashi.
The Wild Liger is introduced as a "legendary" Zoid. This is not just an idle title, as is revealed in episode 44 when Arashi learns of the ancient legend involving the Wild Liger.
The Wild Liger is a unique, stubborn, Zoid. Very few people are allowed near the Liger, and even fewer allowed to touch it, let alone ride it.
Several other people have been able to ride the Liger. Hijiki is let onto the Zoid, a strange twist of fate considering he could not board any other Zoid. Penne is the first member of Freedom to touch the Liger other than Arashi. Much later, in episode 43 Mitsuba rides the Liger with Arashi.
The Liger goes through several trials and tribulations. When learning what happened to Bacon, the Liger goes Berserk in episode 14. This berserk form glows purple and rends Arashi rogue. He remembers nothing while in this state. After defeat in episode 20 Arashi seeks out the Mushi Hermit and learns a new powerful technique called "King of Claw Spiral".
There are multiple variants of the Wild Liger, The model ZW15 is the "Awakened" Wild Liger, and features a more defined colour scheme. It has a top speed of 246km/h.
