## History

### Background

 File:Emu early days.png  Emu Hojo is the son of Kiyonaga Hojo and an unnamed woman. He grew up a lonely child because his father was busy with work and his mother passed away from illness. To ease his loneliness, Emu found love with video games, leading to the creation of *Mighty Brothers XX* that he sent to Genm Corp. in a fan letter. After Kuroto Dan sent him the *Mighty Action C* game, the young Emu was infected with a Bugster Virus strain. While succumbing to the effects, he was involved in a car accident and was rushed to the hospital for emergency surgery. After recovering, Emu was given a WonderSwan handheld game console by Dr. Kyotaro Hinata as a reward. This event inspired him to become a doctor to help children.

 File:Genius Gamer M.jpg  During his teenage years, while he was still on the fence of becoming a doctor, Emu continued winning numerous gaming tournaments under the gaming alias of **M**. Sometime in 2010, Emu trained vigorously for a gaming tournament that he had participated in, at the cost of his health. Unknown to him, Kuroto watched his victory in the shadows, having watched Emu for over a decade.

 File:Emu Bugster surgery.jpg  Shortly after, Emu was abducted by the Next Genome Institute under Kuroto Dan's orders to extract the now-mature Parado from his body, which caused the surgeons operating on Emu to vanish. The leftover residue of the virus in Emu's body created a split personality that represented his love for gaming, while the portion extracted was used to execute Zero Day a year later. Emu believed the operation was a dream and decided to take his entrance exams seriously as he enrolled in Seito University as a medical student.

### Becoming Kamen Rider Ex-Aid

 File:Emu 1st henshin.jpg  During his first year residency at Seito University Hospital, Emu noticed his patient, Sota Suyama, was diagnosed with an unsual disease. While the two bonded over a common interest for video games, Emu later learns that Sota is infected by the Bugster Virus as his patient is transformed into a golem-like creature. Knowing that the Gamer Driver can be used to operate on the patient, Emu took the belt and the accompanying Mighty Action X Gashat to extract the Bugster. After battling the Salty Bugster and saving Sota's life, he is brought into CR where Asuna Karino reveals herself as the navigator, Poppy Pipopapo, as she christens Emu as Kamen Rider Ex-Aid.

 File:Ex-Aid Victory.png  As his battle against the Bugsters continue, Emu would later meet several Kamen Riders like him but is constantly at odds with them due to their viewpoints and ulterior motives. He first encounters Hiiro Kagami, the genius surgeon who initally looked down on Emu's optimism. Next, he faces Taiga Hanaya, a disgraced radiologist who demands the Gashats for himself. Then, he meets Kiriya Kujo, a medical coroner who tries to get along with Emu but would frequently lie regarding his actions.

 File:DAI DAI DAI Henshin!.png  He would frequently face the mysterious "Black Ex-Aid", a dark doppelgänger of Ex-Aid who allies with the Bugsters for an unknown agenda. During one of his fights against the Black Ex-Aid, he managed to obtain the Gekitotsu Robots Gashat to his arsenal, allowing him to level up into Robots Action Gamer. During the final battle against Graphite, Emu acquired the Drago Knight Hunter Z Gashat and unites the three Kamen Riders to synchronize with its power.

#### Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Riders

 File:5 Riders in Movie War 2017.jpeg  Following the intrusion of the Next Genome Institute into Genm Corp. headquarters, Emu would meet Takeru again as the two Riders face off against the threat of the Pac-Man Virus. The two would, later on, be aided by Wizard, Gaim, and Drive in defeating the Institute. During the battle, Michihiko Zaizen revealed that he was the one who operated on Emu as he was Patient Zero of the Bugster virus. His Gamer Driver was forcibly inserted with both the Mighty Action X Gashat and its prototype counterpart, which combined the Gashats into Mighty Brothers XX. This allowed Emu to transform into his Level XX form for the first time. The memories of the final battle along with the revelation would be erased from Emu, due to the trance-like state. Emu would later re-learn the truth about his Bugster infection much later.

#### Kamen Rider Ex-Aid "Tricks": Kamen Rider Genm

Following the Dr. Pac-Man incident, Emu was on his way to Genm Corp. with Asuna to return the Kaigan Ghost Gashat. When he encounters the Collabos Bugster wielding the power of the Proto Gashats, Ex-Aid Ghost Gamer engages the Bugster. Kuroto Dan arrived and gave him more Kamen Riders' Gashats, proving Emu with Full Throttle Drive and Toukenden Gaim. After disabling the Bugster, Ex-Aid was confused to see the Black Ex-Aid assuming a Kamen Rider Wizard based form. With the Black Ex-Aid seemingly completing his collection of Legend Rider Gashats, he completed the Ganbarizing Gashat. Ex-Aid found himself facing manifestations of Kamen Riders Double, OOO and Fourze.

Emu finds himself saved by the sudden appearance of Dr. Pac-Man, who also presented him the three Bandai Namco Gashats. After regrouping with Hiiro and Taiga, Emu takes the Pac Adventure Gashat to become Ex-Aid Pac Action Gamer. Ex-Aid engages in a skirmish Kamen Rider Double in battle and taking Pac-Man's ability of turning Double into a vulnerable ghost to defeat his opponent. Returning back to reality, Ex-Aid saved Poppy from the Collabos Buster and claimed the Ganbarizing Gashat. However, the game is not over as Kamen Rider Hibiki began to emerge.

After Dr. Pac-Man gave Ex-Aid the Taiko no Tatsujin Gashat, he challenges Hibiki in a taiko battle that ends in the victory with the Genius Gamer. While he recovers the Ganbarizing Gashat, Brave and Snipe demanded the Gashat for themselves only for all three Riders to be swiftly eluded by "Dr. Pac-Man" who recovered all the Bandai Namco Gashats and the Ganbarizing Gahsat. It is this point where the Kamen Riders realized they are being manipulated by Dr. Pac-Man and the Black Ex-Aid. Ex-Aid was defeated by the Black Ex-Aid's Critical Strike using the seventeen Heisei Rider predecessors, allowing him to defeat all three Riders with a single Rider Kick. The Black Ex-Aid then took his leave with the Gashats as Emu wondered what exactly was going on.

### The Dark Christmas

During Christmas Eve, Emu and the Kamen Riders finally became aware CEO of Genm Corp., Kuroto Dan, is the true identity of the "Black Ex-Aid", who christens himself as Kamen Rider Genm. Although Emu initially thought it was a lie from Kiriya after he told them, this ended up renewing his trust and friendship with Kiriya. However, this was cut short after Kiriya was killed by Genm Zombie Gamer Level X in hopes of preventing the secret behind Emu's compatibility with the Gamer Driver from being revealed.

### The Mighty Brothers

 File:Parad Emu fate.jpg  Following the death of Kiriya Kujo, Emu completed his pediatrics training and entered a surgical internship, with Hiiro overseeing him. The grief of his Kiriya's death had affected both his performance in the operating table and his prowess in fighting the Bugster. After Hiiro suspended him and confiscated his Gashats, Parado approaches Emu and gives him a mysterious Gashat, which gave him access to Mighty Brothers XX. This allows Ex-Aid to reach Level X as the Double Action Gamer and can also splits into two separate bodies as Level XX.

 File:We're Kamen Riders.png  From behind the scenes, Hiiro and Taiga would learn that Emu was infected with Game Disease since childhood. The two agreed to keep Emu in the dark to not risk him from feeling stressed or worsening his condition. While Brave and Snipe attacked an unaware Emu, it attracted the attention of Parado, who became Kamen Rider Para-DX at at level outclassing the three Kamen Riders.

#### Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~

 File:Emu bloody.jpg  At Seito University Hospital, Emu bumped into an unidentified man. Unbeknownst to him, he had been caught up in the plot of the enigmatic Foundation X, having had their own Level 4 Gashat, Night of Safari, slipped into his pocket. This led Emu to be confronted by the revived serial killer, Takeshi Asakura, who was after the Gashat as part of his sick "game" before becoming bored and proceeding to give Emu a savage beating. Emu would be found unconscious and badly injured by Hiiro, who took the Gashat which was still in his hand, using it to assume Brave Safari Quest Gamer Level 4 with which he defeated Kamen Rider Ouja and his Beast Rider Squad.

### The Patient Zero Revelation

 File:Ex-Aid 18.jpg  After a chain of events that involved Genm Corp. member Tsukuru Koboshi as a victim, Kuroto finally revealed to Emu about his true nature as Patient Zero of the Bugster Virus. This caused Emu to experience a fatal outburst that seemingly subsided. However, this would erratically affect Emu under the influence of "Genius Gamer M". He manages to regain consciousness from Hiiro's words after seeing him overcome the Bugster Virus himself. Although Emu became frightened to continue fighting the Bugster Virus, seeing Taiga fight motivated him to overcome his doubts.

 File:MAXIMUM.png  Emu would learn that the Kamen Riders and the Bugster Virus were intended to be part of Kuroto Dan's ultimate game, Kamen Rider Chronicle and later gets his Gamer Driver destroyed in the penultimate battle against Genm. This doesn't deter Emu at all as he takes Kiriya's Gamer Driver and accesses Maximum Mighty X. As Maximum Gamer Level 99, it grants him the ability to reprogram the Bugster Virus, allowing him to defeat Kuroto and strip him of his powers. However, Emu's efforts were all for naught when Parado killed him with Dangerous Zombie's own power.

### Kamen Rider Chronicle

 File:Ex-Aid 25.jpg  Following the defeat of Kuroto Dan, Emu discovers that Kamen Rider Chronicle had released to the public and Poppy was brainwashed as the game's mascot. The Kamen Riders attempt to save the Ride-Players from their Game Illnesses and save Poppy by reprogramming her. Although doing so made Poppy discover her true nature as a Bugster that harms humans, he assures her that Poppy loves to dance and play with people regardless if they are human or Bugster, allowing Emu to successfully saving her saddened heart.

 File:Ex-Aid 30.jpg  However, Parado decided to act and take over Emu's body. After capturing him, Parado revealed that he is Emu's Bugster and was forced to duel him as one of the two halves of Mighty Brothers XX. Emu is later informed that Parado had saved his life when his game illness flared out, motivating him to fight Parado properly until the Bugster was affected by Ex-Aid's reprogramming attack that evolved Para-DX into Level 99. While Parado continued to take advantage over Emu's game illness, this was stopped upon the return of Kamen Rider Genm, using the power of Level 0 to negate Parado's abilities.

 File:Hyper Invincible Ex-Aid!.png  While the Kamen Riders faces off against the high tier Bugsters to clear Kamen Rider Chronicle. As the game continues, Masamune Dan reveals himself to be the true mastermind and becomes Kamen Rider Cronus. Because of his exploitation of Pause and holding the Proto Gashats, Hiiro was lured into working with Masamune and Kiriya is revived as Lazer Turbo. To counteract Cronus, Kuroto created Hyper Muteki. While he initally failed to access the the Gashat, it was through Lazer's tactics and Emu himself reinfected wth Parado's virus where Ex-Aid evolved into the Ex-Aid Muteki Gamer.

As the battle with Cronus progressed, Hiiro Kagami would return to CR to fight with the Kamen Riders once more. Emu later recognizes Parado's fear of death and seemingly killed Parado at the cost of his transformation. He revive him later and have Parado see the errors of his ways, joining forces with him in the fight against Cronus. After some trials and tribulations, the Kamen Riders advanced to the final stage of Kamen Rider Chronicle, preparing to confront the last boss Gamedeus.

### The Gamedeus Pandemic

With Gamedeus and his Bugster Virus pandemic spreading rapidly, Ex-Aid and Para-DX fought against him while the other doctors stayed behind to take care of the patients. Although the Doctor Mighty XX Gashat developed by Kiriya and Kuroto managed to weaken him, Masamune barged in to absorbed the Bugster into his own body at the last minute. This resulted in the fusion known as Gamedeus Cronus, proclaimed to be Chronicle's true final boss, reigniting the pandemic and turning his victims into Bugster Viruses until Poppy sacrificed her life with the Doctor Mighty XX Gashat.

 File:Endless Game.png  Emu would face Super Gamedeus head on as Ex-Aid Level 1 with the Kamen Riders to seperate him from Masamune Dan. But when Parado followed in suit, he sacrifices both his existence and Emu's transformation. As all hope seemed lost, Emu miraculously regained his infection, allowing him and the remaining Riders defeated Cronus once and for all. However, in their final confrontation, Masamune kills himself with the Master Gashat, this removing the only way to rescue the data of the patients within the Proto Gashats. Despite that, Emu remained confident that people trapped in the data will one day return.

While Emu returned to CR, he discovers Poppy was revived by Kuroto from what was left of her data. Kuroto later revealed that the same occurred with Emu and Parado, which explains why he could still transform during the final battle. Emu rejoices to the fact as he reunites with Parado before Emu goes to take on another medical case.

### Kamen Rider Ex-Aid: True Ending

After Cronus' defeat, Emu is assigned to his latest patient Madoka Hoshi, a 7-year old girl who needs daily treatments. However, new outbreak of the Bugster virus occurs that rainy day as Kamen Rider Fuma storms Seito University Hospital with his Ninja Gamers. With most of his teammates incapacitated, Kuroto creates the Mighty Creator XX for Emu to free the people trapped inside the Game World. While Ex-Aid Creator Gamer succeeds, Madoka refuses to leave the Game World.
