This is MY take on the Americanization of Kamen Rider Blade.

The Premise
Ten thousand years ago, a massive battle known as the Battle Royale was fought by fifty-two Undead, each representing a species fighting for dominance over all others. The winner was the Human Undead, known as Type Two of Hearts, giving dominion of the Earth to humanity. In the present day, archaeologists discover the sealed Undead, and accidentally set them free. Thus, a new Battle Royale begins.

To counter this and reseal the Undead, the archaeologists, who were part of an organization known as the Board Of Archaeological Research & Discoveries (BOARD), develop a system based on the Joker's ability to copy sealed Undead. That system was a Rider System and equip them to two men to use it to protect humanity from the Undead.

The names have a connection to the animal. Jackson refers to the Japanese word for Peacock "Kujaku". Rose is a type of flower like an Orchid and a Gardener tends to plants. Bob because part of it sounds like a goat's bleat. Avery as in Aviation which refers to the flight. Logan because it's a bit like Lobo which, if I recall correctly, is Spanish for "Wolf". Vin Graves because of the elephant graveyard in "The Lion King" due to the elephant skulls on his shoulders and I see this guy as like Vin Diesel. Eddie Webster refers to Spider-Man's enemy Venom aka Eddie Brock and Webs. Tina Spencer because of the hissing sound & Serpentine. Brock Banner sounded like a great name for a strong & powerful Undead. He's named after Wrestler Brock Lesner & super hero Bruce "Hulk" Banner. Lily Jade because of the color green and Tiger Lily. Rex West was just some random name I thought up.
