During Kouga's battle with the Spider Horror, a BMW 8 Series is destroyed. However, this is not the first time this car has got in the way; in episode 2, "Yin Self", an 8 Series is thrown by Ishtarb and promptly obliterated by GARO.
Despite being heard several times throughout the episode, a helicopter is never seen or mentioned.
Like GARO, ZERO cannot maintain his form for more than 99.9 seconds without being burnt by the metal.
First appearance of Silver Fang ZERO, Rei's Makai Knight form, and his Ginrouken Swords.
