Bols

Bols was the oldest member of the Jaegers. Before joining them, he was a member of the Incineration Squad. He wore a mask that obscured his face.

Not much is known about him other than the fact that he was married and had a child. Despite his appearance, he seemed to be shy around other people, staring at Wave for several minutes before finally introducing himself. He was a skilled cook and often made meals for the team.

Appearance
Bols was always seen wearing his mask as an incineration squad member and has a gasoline tank mounted at his back for his flamethrower. He wears long gloves over his hands which serve not only to help him when using the flamethrower, but also for protecting Bols from attacks. He also had a scar on his upper chest.

Personality
Contrary his grizzly appearance, Bols is a very kind and caring person. He is also quite shy and timid, a good example of this was him making a long pause before first introducing himself to Wave or when he keeps his mask on despite his wife complaining that his face wouldn't cause trouble for others. Despite his kind and caring personality, Bols is wracked with guilt over the jobs he's had incinerating villages and believes that one day karma will catch up to him; however, he still does his job for the sake of his wife and children. Due to him having incinerated many villages and the people dwelling in them, he is thus very reluctant to kill mass groups of people who he believes have no crime at all. This led him to believe that many people despised him and swear vengeance on him. Bols loves his family very much and will always be composed so long as they are fine. His love for his family was shown to be very strong when his last act in his life was to attempt to return to his home in order to see them one last time.

History
Prior to his entry as a Jaeger, Bols was originally working for the Empire's incineration squad. He comments that he was mainly used to carry out severe executions by burning his victims to death or burning down entire villages, and that at some point in time he would have to pay for these atrocities. Despite his background he eventually gets married for six years and also has a daughter. Together, his wife and daughter usually comfort him during work or when he's having emotional problems. When he was called to the capital due to him being a Teigu user, he quickly becomes acquainted with other users who were also called. He had been particularly close with Wave, who had arrived just after him. Soon he along with the other Jaegers (and Tatsumi who had been dragged along by Esdeath), assault a nearby bandit fortress. He becomes well known by the bandits as he uses Rubicante to burn the bandits on top of the walls. Later he is asked by Esdeath for advice regarding Tatsumi, in which Bols replied that she mustn't give up hope until Tatsumi finally falls for her. Later he (or at least his squad) had burned down a village loyal to the revolutionary army. This would eventually mark him out as a main target for the Night Raid.

Later he along with Wave and Kurome split up from Esdeath, Seryu and Run, who attack Najenda's position, while he alongside Wave and Kurome proceed to attack Akame and Mine. The trio unknowingly end up falling into Najenda's trap and are not only ambushed by Akame, Mine and Najenda, but also Leone, Tatsumi (using Incursio) and Susanoo. Susanoo also makes quick work of Wave by knocking him into a far and unknown area after he protected Kurome from Susanoo's attack. Soon a battle ensues between Night Raid and the remaining Jaegers. He ends up fighting Akame, but her attacks fail to impact him due to the protection of one of Kurome's puppets, Woll. Initially both sides seem to be evenly matched as Bols can't shoot Akame due to her speed, but she can't attack Bols properly thanks to Bols' protective gear as well as aid from Woll. Soon during the fight a crippled Leone, who had her left arm chopped off by Kurome comes in to aid Akame. The tide soon changes in favor of Akame and Leone, forcing Bols to use his trump card. In an attempt to kill both Akame and Leone, Bols self-destructs the gas tank of his flame thrower successfully hitting both Akame and Leone, causing Leone to collapse from her wounds. Though wounded, Bols manages to escape the explosion, but comes across a girl who had scratched her leg. He then moves in to bandage the girl's wound, but the girl, who is Chelsea in disguise, proceeds to kill Bols. She then tells Bols that the girl he just saw was from a village that he burned. In his last moments, Bols attempts to crawl his way home in order to see his family once again, but dies from his wounds. Chelsea then proceeds to take Bols' armaments and disguises herself as Bols.

Legacy
Bols' death affected Kurome and Wave greatly, with Kurome flying into a rage upon realizing that Chelsea had killed him and ordering her brutal death.

Following his death, his daughter and wife were killed by Syura and other members of Wild Hunt at his grave. This cruelty, especially towards someone he respected so much, sent Wave over the edge. After punching Syura in the face when he threatened Kurome, Wave defeats Syura in a fair one-on-one battle.

The way Run defeated Champ was also a shout-out to Bols, as it represented an allegorical vision of him having come down as an Angel to avenge his daughter.

Equipment &amp; Skills
Bols wielded a flamethrower Teigu, named Purgatory's Invitation: Rubicante. With this weapon, he was seen setting large groups of enemies on fire that will not extinguish even if the target submerges themselves in water. He had impressive strength as one could expect from a man of his physique, and can beat Danger Beasts into submission with his bare hands.

Aside from his fighting capabilities, Bols is actually a good cook, and is the one who usually prepares food or tea for his fellow Jaegers.
