== Throughout The Series==
===Ag-Sec breach===
Boki makes his first appearance following the breach of one of the Ag-Sec carts in which a window is broken and everything inside freezes to death. When [[Melanie Cavill]] and [[Bennett Knox|Bennett]] investigate, it is deemed that emergency repairs are needed. Melanie remarks that they can throttle power back by 10%, perhaps 12% at a push, however Boki remarks that he'll need at least 25% to repair the train properly. Despite this, Melanie reveals that 12% is the maximum amount they can afford given their current circumstances.<ref>''[[Prepare to Brace]]''</ref>

[[Bennett Knox|Bennett]] mentioned that Boki is leading a team which was assigned to fix the [[Cattle Car]]'s window.<ref>[[Access Is Power]]</ref>

===Near-derailment===
Boki appears as a Breach Team worker showing how it's like aboard ''[[Snowpiercer]]'' to the classroom. He is then called by [[Melanie Cavill]] to the subtrain to fix a hydraulic piston.<ref>''[[Trouble Comes Sideways]]''</ref>

===The Revolution===
Along with the rest of the Breachmen, Boki sat out the revolution, mourning the apparent death of [[Joseph Wilford|Mr. Wilford]].<ref name="Odyssey">''[[A Great Odyssey]]''</ref>

===The Return of Mr. Wilford ===
Boki and the Breachmen are suspected in the attack on [[Lights]] by Wilford supporters following his return in ''[[Big Alice]]''. Although Boki proudly declares himself as a Wilford supporter, he insists that he had nothing to do with the attack.<ref name="Odyssey" />

Boki is later attacked by a revenge-seeking Lights and several Tailies, but continues to protest his innocence. A brawl breaks out when the other Breachmen get involved, before [[Bess Till]] breaks it up. Boki later flashes the Wilford sign at Till from the bar.<ref>''[[A Single Trade]]''</ref>

As the investigation continues, Layton gets word from [[Josie Wellstead]] that Wilford is planning something with the Breachmen. As Layton and [[Roche]] confront a confused Boki, the other Breachmen are assassinated by Wilford agents in a coordinated attack, leaving Boki as the only survivor.<ref>''[[Keep Hope Alive]]''</ref>

Boki is left grieving the deaths of the Breachmen, his family and believes the Tail to be responsible. Although [[Pastor Logan]] promises to keep an eye on Boki, he lets Boki out and he assaults the Tailies in anger. Till later realizes that Pastor Logan was the actual mastermind and that he purposefully let Boki go in order to cause trouble. Pastor Logan commits suicide before Till can force him to reveal the truth, however.<ref>''[[Our Answer for Everything]]''</ref>

=== Switching Sides===
The next day, the still-grieving Boki dumps the bodies of the Breachmen off of the train on a bridge as a form of a funeral. Layton and Till reveal the truth to Boki, but he refuses to believe it. After the water intake is damaged, Layton calls upon Boki to fix it which he reluctantly agrees to do. Boki manages to remove a railroad spike from the intake with some difficulty, fixing the problem.

Meeting with Layton, [[Bennett Knox]] and [[Javier De La Torre]] in [[the Engine]], a disgusted Boki reveals that the train was deliberately sabotaged by Wilford, having seen proof of [[Icy Bob|someone else]] on the access ladder before him. Bennett and Javi leave Layton and Boki alone and Boki holds up his Wilford pin and reveals that Wilford gave it to him personally as a promise that as the Breachmen put their lives on the line for Wilford, Wilford would do the same for them. Now on Layton's side completely, Boki turns his pin over to Layton, addressing him as "sir" for the first time and suggesting that maybe Layton can shove the pin up Wilford's ass one day for him.<ref>''[[The Eternal Engineer]]''</ref>

Boki helps to smuggle Layton and Ruth back aboard ''Snowpiercer'' and works with Layton as they prepare to bring Melanie back onboard. However, Wilford sabotages the plan. As Layton and Boki make their way back uptrain, Alex emerges from the subtrain and proposes a plan to create a [[Pirate Train]] by disconnecting the [[The Aquarium|Aquarium Car]] with Boki supporting her plan, stating that ''Big Alice'' can handle powering ''Snowpiercer'', but it will hobble Wilford which is only to their benefit.<ref name="Into the White">''[[Into the White]]''</ref>

===Presumed Death===
As part of the plan, Boki works to manually disconnect the two J-Links on either side of the [[The Aquarium|Aquarium Car]]. However, as he works on the second J-Link, Boki is attacked by six [[Jackboots]] and struggles to fight them off and complete the job. With no other choice, on Bennett's signal, [[Josie Wellstead]] breaches the entire Aquarium Car from the outside, destroying it completely, after Boki and the Jackboots evacuated the subtrain.<ref name="Into the White" />

In reality, Wilford's men rescue Boki from the destruction of the Aquarium, although he is left even more badly scarred. [[Mrs. Headwood]] gives Boki the Headwoods' cold treatment and nurses him back to health over six months, rendering Boki impervious to pain in the process.<ref name="Sinners">''[[The Original Sinners]]''</ref> While [[LJ Folger]] is visiting the Headwoods' lab on ''[[Big Alice]]'', she notices Boki's groans of pain, but Mrs. Headwood dismisses them before going to comfort Boki.<ref>''[[Setting Itself Right]]''</ref>

===Wilford's Cold Man===
Six months after his apparent death, now apparently brainwashed back to Wilford's side and only communicating in growls, Boki flings [[John Osweiller]] out of the Night Car on Wilford's orders and enjoys testing his new painless state. When Melanie and Layton exile Wilford on the [[Track Scaler]], [[Ruth Wardell]] lures Boki out of the room and [[Lights]] manages to knock him out by hitting Boki in the head with a celling vent. Mrs. Headwood later treats his injuries as Melanie and Layton make an announcement offering people a choice between ''Snowpiercer'' and New Eden.<ref name="Sinners" />

===New Eden===
Boki chooses to join ''[[Big Alice]]'' in going to New Eden alongside [[Mrs. Headwood]], bracing himself when the train derails and then joining the others in emerging from the train to enjoy the warmth.<ref name="Sinners" />
