Tenjuro Banno

Tenjuro Banno (蛮野 天十郎) was a scientist and friend of Krim Steinbelt, and Go and Kiriko Shijima's birth father. He created the Roidmudes, unique androids that were capable of "evolving" to become more like humans. Later, he creates a knockoff of the Drive Driver, dubbed the Banno Driver (バンノドライバー) and transforms into Kamen Rider Gold Drive (仮面ライダーゴルドドライブ) or simply called Gold Drive (ゴルドドライブ) by himself.

Past
When his development of the Roidmudes had hit a wall, Banno asked his friend Krim Steinbelt for help. Steinbelt gave them the prototype Core Driviars to continue their evolution. However, Banno began to planning experiments which become more lethal. He forced 002 to copy the appearance of the businessman who had refused to invest in Banno's research. Banno later gets his revenge by torturing 002 as if the latter was the actual investor, before Krim saves 002. Krim blamed him for such a malicious act, and it led to the end their friendship and partnership. Soon after, Banno began to implant the evil chip containing negative emotions (starting off with 001 and 003). At that time, he secretly stole Krim's mind uploading technology.

Present
Banno's body was killed by the first three Roidmudes, but his mind was later uploaded and became a procedure stored in a tablet computer Brain stole from a bystander during 029's revival, and would later be used to help reset Roidmude Cores.

When Go found out the truth after Brain used Banno to shelter him from a blow from the Zenrin Shooter while he was down, the Kamen Rider went undercover to save his father, playing the role of the betrayer like a world-class actor. With Chase's interference on barging to the high ranked Roidmudes' hideout when he thought Go's mind was influenced by Freeze, Banno was ripped from Brain's possession by Go and escaped with Banno.

Though he was safe thanks to his son, he was still in danger and remained targeted by the Roidmudes.

True facade revealed
While he seemed willing to help Go and his friends, it turned out that he was simply manipulating them for his own sinister ends. He attacked them by gaining control of one of the Ride Boosters and opened fire on the Riders when they tried to rescue Kiriko from being abducted by the Tornado Roidmude, causing a burned Shinnosuke to fall off a cliff and lose Mr. Belt to a Roidmude and an overwhelmed Go to face Heart alone. Later, with the stolen data from Drive Driver, Banno successfully transfers his will into a new Driver called Banno Driver. In a case where Medic attempts to reach her Super Evolution, Banno manages to steal her body, but finally he decided to use Roidmude 006's body whose Core Driviar was almost on par with that of a Super Evolution and uses it to transform into "Gold Drive". Banno also reprogrammed Medic to be killed when he needed a stabilizer for his Sigma Circular. However, his plans are foiled when Brain sacrifices himself instead, saving Medic.

Banno initiates his plan to start a worldwide Global Freeze alone after sacrificing Roidmude 004 to self-destruct on Heart, Medic, Shinnosuke, Go, and Chase. When the Sigma Circular starts to activate, Go and Chase fight Banno. However due to prior injuries, Go is weakened, causing Chase to defend him, before ultimately self-destructing in an attempt to take down Banno.

Death
Banno, undamaged from Chase's suicide attack, attacks a vengeful Mach, and insulted Chase's death as having no worth. Mach soon used the Signal Bike Chaser to become Kamen Rider Chaser Mach, turning the tide of battle over to the white Rider. When Banno tried paralyzing the Rider, Chase's Chaser Viral Cores arrived to undo the paralysis, merging with the Rider's armor, and eventually destroys Gold Drive/006 with a Rider Kick. Still alive in the Banno Driver, Banno threw away his cover laughing madly as he described his final plot, but a detransformed Go ends Banno's reign of terror by using the Shingou-Ax's Full Throttle onto the Banno Driver despite Banno's desperate pleading to spare him, shattering the Driver into unsalvageable scrap.

Personality
Banno as a human is viewed in flashbacks as a cruel, sadistic man whose constant failures to advance or complete his Roidmude research drove him to insanity. He was also petty as during one of his experiments on his sentient androids, he made one into the likeness of a billionaire who refused to invest in his research to enact his fantasies of torturing him. He also displayed narcissistic tendencies, as he believed anyone who did not understand his supposed genius were beneath him and enjoyed making those kinds of people suffer. To him, the concept of familial love is a foreign notion. He never viewed the members of his family as anything more than research subjects.

As an A.I., Banno is more cold and manipulative but retains some of his human traits such as his sadism and his desire to further his scientific goals, as well as his insanity. He also is abusive and manipulative to his Roidmudes, seeing them as nothing but expendable pawns towards his ultimate goal of recreating the Global Freeze. One example of this is him tricking Medic into letting him help her with her Super-Evolution. He then secretly installed some kind of a trojan program when she evolved which wiped her A.I. and memories rendering her a broken, mindless puppet who obeyed his every command.

Banno, despite being cruel and sadistic, fears his existence ending, screaming for Go to not destroy him after being defeated by the latter. Before his final moments, his ego showed by frantically claiming to Go that by destroying his consciousness he would "rob the world of its greatest scientific mind" and begged his son not to kill him. Unfortunately for him, Go was more determined in destroying him after all the pain and death he had caused, swinging down the Shingou-Ax and smashing the Banno Driver. The last thing the demented scientist ever did was scream in fear and pain at his own impending death before he was finally destroyed.
