Boris the Wolf

"Do we have a wolf in sheep's clothing...?"

Boris the Wolf and his later, twisted form "Boris", is a major character in the horror video game Bendy and the Ink Machine.

Boris serves as an antagonist in the cartoons made by Joey Drew Studios, usually pitted against the heroic Bendy. However, when the cartoons are brought into the real world by the Ink Machine, Boris is actually one of the few friendly characters until he is brainwashed and twisted into "Boris" by "Alice".

Personality
In the cartoons, Boris appears as a brutish and mischievous trickster who likes to eat and antagonize Bendy. He will steal Bendy's food and candy for himself, and eat it right in front of Bendy. When Bendy attempts to get back at him or gets in his way, Boris gets angry and will chase Bendy down, showing he cannot only be cold, but wrathful and even somewhat violent.

When Boris is brought into reality by the Ink Machine, his personality changes (similarly to the other characters), but his changes to more heroic. While Bendy and Alice Angel become corrupted by their physical forms and turn evil, Boris actually becomes softer and more friendly, as well as helpful and even playfully mischievous.

However, when Boris falls into the hands of "Alice", he is experimented on and twisted into the new physical form of "Boris". His mind has been warped as well, turning him evil, destructive, brutish, and violent, even more so than his original cartoon version.

Tombstone Picnic
Bendy goes for a picnic in a graveyard, but is interrupted by a mischievous skeleton. While he is dealing with the skeleton, Boris steals his picnic basket and begins eating his food. When Bendy confronts Boris, Boris simply pulls the picnic blanket out from under him and trips him up. Bendy gets an idea, and sneaks a bottle of soda. He then shakes it up and splashes Boris, angering the wolf and causing him to get angry. However, Bendy runs away and escapes.

Haunted Hijinks
Bendy goes trick-or-treating to Boris' house, but the wolf refuses to answer the door and instead naps in the living room. Bendy decides to play a trick on Boris, and dresses up as a ghost in an attempt to scare Boris. Boris, however, comes to the door in his own ghost costume, scaring Bendy away so he can steal the demon's dropped candy.

Snow Sillies
Bendy makes a snowman. When Boris comes by with a basket of carrots, he drops one and Bendy uses it for a nose. However, the sun comes out shortly after, melting the snowman. Boris then come back and picks up the carrot and begins eating it, leaving Bendy crying over his ruined creation.

Chapter 1: Moving Pictures
As Henry explores the seemingly abandoned studio, he comes across posters of a Boris short called "Sheep Songs" and the corpse of an imperfect Boris clone strapped to a table with its ribcage pulled open.

Chapter 2: The Old Song
After escaping "Bendy" and Sammy Lawrence, Henry enters the S3 vault an notices a rolling can. He demands that whoever is there show themselves, leading to Boris stepping out from the shadows.

Chapter 3: Rise and Fall
Henry teams up with Boris and, after making the wolf a bowl of bacon soup, the two head out into the dark hallways. Boris is frightened, and Henry must stay with him during the venture. Eventually, the two will come across a locked door. Boris borrows Henry's flashlight and crawls through an air vent to unlock it from the other side. The two are briefly separated until he comers across the "demon" or "angel" paths. The two will be reunited, and Henry will obtain the Gent pipe as a weapon to defend Boris.

As the two continue on, Henry must fight off Piper and defend Boris. He will also send Boris to pull a lever with him and open a gate, leading to the elevator. Once the two reach level nine, they find a series of gutted clones of Boris, all killed by "Alice" to help rebuild herself.

For the rest of the chapter, Boris will wait on the elevator as Henry carries out his tasks. If enemies are nearby, he will cower in fear until they are taken away or defeated.

However, at the end of the chapter, "Alice" betrays the two and says she wants Boris' insides to make herself "beautiful", as he is the only perfect creation. She crashes the elevator, leading to Henry being knocked out. As Boris tries to wake Henry up, he is pulled away by "Alice".

Chapter 4: Colossal Wonders
Henry comes to and goes on a mission to save Boris from "Alice", despite her mocking him for his efforts and teasing him about what she will do to the wolf.

Towards the end of the chapter, Henry realizes his efforts have been in vain, as "Alice" has corrupted and twisted Boris into "Boris", a monstrous, brutish version of his past self. "Boris" attacks Henry by throwing large objects at him, and Henry is forced to obtain weapons and kill his former friend.
