Zyudenryu Bunpachy

Zyudenryu #8 Bunpachy (獣電竜八号 ブンパッキー) is the Pachycephalosaurus-themed Zyudenryu that was Kyoryu Gray's partner.

This Zyudenryu is usually normally hidden behind the Mannen Falls (万年滝) in China until summoned. When assuming Battle Mode, his "forehead" deattaches to become a spiked flail for a tail, all while revealing his true forehead, which resembles a yellow hard hat on his head. When combined with a Zyuden Giant, Bunpachy's flail is then called the Bunpachy Ball (ブンパッキーボール).

History
One of the Ten Great Zyudenryu members, Bunpachy was a Pachycephalosaurus that agreed to be modified to fight the Deboss Army in ancient times, but was lost over the eon-long war with the invaders.

Bunpachy was sought after by Ramirez, who is close to finding the wayward modified dinosaur. Bunpachy was later found along with the Spirit of his partner, who trains the modern-day Kyoryugers to see if they are worthy of receiving Bunpachy's power.

Beast Battery

 * Bunpachy (ブンパッキー) Beast Battery (獣電池): 4 gray Beast Batteries (originally 2) holding the Kyoryu Spirit of the Pachycephalosaurus; associated with Kyoryu Gray. Three copies of this battery are given to the present Kyoryuger team, while the fourth is utilized by Kyoryu Gray. When used in a Gaburivolver, it unleashes an attack similar to Kyoryu Gray's Violent Breakthrough technique called Iron Ball Brave Finish (鉄球ブレイブフィニッシュ). Kyoryu Red Carnival can use the Beast Battery to equip the Bunpachy Ball Arm (ブンパッキーボールアーム).

Etymology
All of the Zyudenryu/Beast Batteries sport a name that is a portmanteau between their effect/motif and their respective animal name, Bunpachy is a portmanteau of Buun (the Japanese onomatopoeiac word for "swishing") and Pachycephelosaurus.
