He is always eager to learn and open up about his identity. This makes his team protective of her, as evidenced when they leapt to his defense when he and his boyfriend were harassed by homophobic bar patrons in Season 10, Episode 4, “The Right Thing.” Ritter has been able to grow as a firefighter without losing his personality, which makes him a great addition to Firehouse 51 and Chicago Fire overall.

Lieutenant Herrmann is a mentor figure to several of the younger firefighters at his firehouse. He has stated several times that he feels it is his responsibility as an older firefighter to dole out advice to the next generation. This is evidenced by the hard advice he gave Ritter in Season 8, Episode 1, “Sacred Ground,” about following orders in the field. Herrmann proves time and time again throughout Chicago Fire that he is one of the best educational supports for young firefighters.
3.Taylor Kinney as Kelly Severide is a Passionate and Devoted Firefighter

Kelly Severide made waves right from the moment he was introduced as a main character in the pilot episode of Chicago Fire. Severide is a character-driven by emotion. Emotionally, he burns as hot as the fires he fights and is just as hard to extinguish.
When Kelly Severide comes across situations of injustice in the field or in his personal life, he leaps at the chance to make it right. This is seen when he zealously hunts down a serial arsonist targeting his firehouse, culminating in Season 2, Episode 4, “A Nuisance Call.” Kelly’s passion has resulted in mistakes both personally and professionally.

There is no doubt that Deputy District Chief Wallace Boden Jr. is the best character in the series due to his protective nature over the firefighters and paramedics under his command. Boden has fought tooth and nail to protect his people, both at fires and politically, on numerous occasions. Outside of his role, he still is a protective figure and is always there for anyone in need.
Chief Boden has been with the Chicago Fire Department for over 30 years and clearly views his occupation as more of a calling than a job. This calling contributes to his passionate leadership skills that lead his firefighters and paramedics to hold him in incredibly high esteem. So much so that he was asked to walk Lieutenant Stella Kidd down the aisle in Season 10, Episode 22, “The Magnificent City of Chicago.” Chief Boden’s protective nature allows his people to flourish and thrive in a safe environment under him, making him the best character in Chicago Fire.
