This badly produced series stands out in my memory for two reasons:
A) Zombies in a cartoon. How could they make Dawn of the Dead into a cartoon for kids and sell toys for it? The way the diesase spread and the look of the zone is very much like the modern film version of zombieism.
B) It is one of the few American cartoons featuring an Asian male as one of the main characters, Lt Hiro Taka. Sure, there was Sulu in the animated Star Trek, but that was only because he was in the live-action show. There were other cartoons that featured Asians, but they were Asians in an (stereotypical) Asian world like Hashimoto-san or The Chan Clan. Usually when an Asian is featured in an international team (always at least two Whites, a Black, and an Asian), that character is almost always famale.
