Hiroshi Tennoji

Hiroshi Tennoji (天王路 博史, Ten'nōji Hiroshi) is the chairman of BOARD who intentionally set up the series of events in the fake Battle Fight and the creation of the Catergory Ace Keroberos, so that he could have his dream come true. This warped dream was of a new world order with himself as its ruler.

Keroberos II Undead
Tennoji sealed the Kerberos Undead himself into the Change Kerberos card for his true plan: Using a surgically graft device based on the Rider System technology to fuse with his creation, becoming Kerberos II with Tennoji's face on the monster's chest. It took all 4 Riders to fight Tennoji/ Keroberos II, with Blade King Form's Royal Straight Flush and Wild Chalice's Wild Cyclone to stop the fusion. However, the Giraffa Undead takes the Change Keroberos for himself in the fight's aftermath for his own agenda. In the end, he was murdered by the Giraffa Undead after he was defeated by the Riders with his dreams shattered.
