Charles Boyle can still fight criminals because Brooklyn Nine-Nine treats him as resourceful, brave, and persistent rather than physically dominant. The show also repeatedly shows him using grit, timing, teamwork, and surprise more than raw strength.

Why he works as an officer

Boyle is described as the precinct’s “workhorse,” someone who “tries harder than anyone else,” and he has good gut instincts and the trust of the squad. That means he contributes through detective work, commitment, and willingness to act under pressure, not just athletic ability.

How he handles danger

Even though he is not physically gifted, the character is shown doing very brave things, like jumping in front of an armed criminal to protect Rosa and taking bullets in the process. Fan discussions also point out that he can surprise people with aggression, confidence, and stubborn follow-through when a situation turns dangerous.

In practice

So the short answer is:

  • He is not a superhero or brawler.
  • He relies on courage, instincts, and teamwork.
  • When needed, he can still be surprisingly tough and willing to take risks.

If you want, I can also explain this as a Brooklyn Nine-Nine character analysis or in a more funny, meme-style way.
