Friender

Once known as Tetsuya's loyal pet, Lucky, this brave robotic canine was resurrected as Friender using salvaged data. Serving as a versatile ally to Casshern, the dog can transform into various vehicles like tanks or jets and even breathe fire to combat the Andro Army. Though he initially followed Casshern from a distance after the destruction of a peaceful robot community, he eventually formed a deep bond, acting as a vital protector to restrain Casshern during his berserk episodes.
