A medium-sized Zoid discovered by you. It resembles a lion species, but its skeletal structure is slightly different and it is suspiciously agile. It utilizes a combat style based on high-speed movement, claws, and fangs, and can easily defeat Black Rust. Furthermore, it can completely sever "only the Black Rust" from Zoids that have been corrupted. When using the mysterious release "Gen-Shi Blast," massive green and cherry-blossom-colored claws deploy from its back, transforming it into a form further specialized in speed and attack. It is the only being unaffected by corruption from Black Rust. It also possesses a self-repair function. In fact, when discovered as a fossil by you, it was the Liger itself that restored its body using this function. It recognizes you as its pilot and is attached to you. White skeleton, black armor, cherry-blossom eyes, claws, and fangs.

However, in this cooperation with the Republic, he will likely be a powerful weapon for both sides. Black hair, center-parted, odd-eyed with a blue right eye and a red left eye.

Kill's Zoid. Specialized in solo covert operations, it possesses high stealth capabilities due to its Horizontal Armor, which is difficult to detect by radar, and Shadow Claws that absorb impact to silence footsteps.
