Shadow Bonnie is a black rabbit and the brother of both Grimm Foxy and Shadow Freddy, as well as his second-in-command. He worked with Grimm Foxy, while infiltrating Fredbear's Family Diner, and later Freddy Fazbear's Pizzeria in London. He speaks with a glitchy English accent and has unwavering loyalty to Shadow Freddy.

History:

Creation and Early Infiltration (1970–1980)

Created in 1970 by Shadow Freddy and appointed as his second-in-command, Shadow Bonnie gained the same supernatural abilities as his creator. He was sent to Fredbear's Family Diner in 1979 alongside Grimm Foxy to look into destroying the establishment, spending time hiding and watching from the shadows until 1980. During this period, the original Puppet Foxy was temporarily taken from the stage after being damaged. Unbeknownst to most, Puppet Foxy had actually been ambushed by Shadow Bonnie and interrogated on behalf of Shadow Freddy. When Puppet Foxy refused to help and tried to shout for Fredbear and Spring Bonnie, Grimm Foxy beheaded him, subsequently assuming his identity as a disguised voice box replacement. Meanwhile, the modified Puppet Foxy returned to the stage completely changed—becoming withdrawn, protective, and passive-aggressive—which strained relations with Spring Bonnie.

The Fazbear Band Era and Conflict (1983–1989)

In late 1983, following the retirement of Fredbear and Spring Bonnie, Puppet Foxy was relegated solely to the Prize Corner. Spring Bonnie, who possessed the ability to predict time and heavily distrusted Puppet Foxy, was eventually caught eavesdropping on a conversation between Grimm Foxy and Shadow Bonnie; he was killed and placed under mind control by Puppet Foxy for six months until mid-1984, when Fredbear helped him break free.

Later, Grimm Foxy and Shadow Bonnie were sent to Belfast by Fredbear (acting as Shadow Freddy) to deal with base issues. Upon returning, Grimm Foxy doubted the orders, but Shadow Bonnie believed them. Upon arrival, they were confronted by Phantom Foxy and Phantom Freddy, who summoned Shadow Freddy. Shadow Freddy beat them both nearly to death before allowing them to return with a warning.

By 1989, after Fazbear Entertainment commissioned the Fazbear Band and renamed the venue "Freddy Fazbear's Pizzeria," Fredbear and Spring Bonnie formed an alliance with the band to counter Grimm Foxy and Shadow Bonnie. During a surprise attack by Grimm Foxy, Shadow Bonnie, Shadow Freddy, the Toys, Phantom Foxy, and Phantom Freddy, Shadow Freddy controlled Fredbear while Shadow Bonnie controlled Spring Bonnie to damage the entire band. Spring Bonnie then stabbed Fredbear before Grimm Foxy delivered the final blow after Spring Bonnie regained his senses. Afterwards, Shadow Bonnie returned to monitoring the cameras while Grimm Foxy returned to his disguise.

The Toy Generation, Coup, and Alliance (1990)

In 1990, Fazbear Entertainment introduced the Toy Animatronics. Grimm Foxy immediately planned a coup against Shadow Bonnie's leadership with the backing of the Toys (minus Toy Foxy). Loyal to Shadow Bonnie, Toy Foxy proposed an alliance with the Withereds. Despite his hesitation due to past trauma from the "Dogs of War" and fear of Shadow Freddy's anger, Shadow Bonnie briefed Toy Foxy and teleported into Parts and Services, where a hostile Withered crew initially rejected him until Toy Foxy intervened.

Hours later, after letting slip the plans to the suspicious Toys, Grimm Foxy confronted Shadow Bonnie, revealing that he had murdered Toy Foxy. Shadow Bonnie summoned Shadow Freddy, who confronted Grimm Foxy and the Toys, ordered Shadow Bonnie to stand down, severed all Syndicate ties with Grimm Foxy, and warned Shadow Bonnie never to return past the Nightguard's Office.

Upon leaving, Shadow Bonnie was ambushed and accused of Toy Foxy's murder by Withered Bonnie and Withered Foxy, then taken before Withered Freddy. Though nearly killed for mentioning his brother, Shadow Bonnie was spared and placed under strict monitoring by Golden Freddy and the Withereds as they worked to revive Mangle.

Aftermath and Surveillance (Present)

Following the burning of Toy Freddy's Pizzeria and the apparent destruction of the Toys and Grimm Foxy, Shadow Bonnie returned to Belfast to brief Shadow Freddy and agreed to survey the new branch. However, a familiar Grimm Foxy hook hinted at his survival, and Shadow Bonnie was subsequently captured by Chica and Freddy after they recognised him from their withered days in 1990 and for his role in helping fix Mangle.

Personality:

Shadow Bonnie is quite cold and calculated. He does not plan for the future, but instead the present time. He is loyal to Shadow Freddy and slightly to Grimm Foxy, but reminds him he is the commander of him. Shadow Bonnie is also very good in a fight, being able to teleport and deliver damaging attacks when in combat. He can also hack the cameras and disrupt the establishments lights and system.
