Honestly, if you’d told a Criminal Minds fan five years ago that the BAU would eventually recruit a vigilante hacker with a dishonorable discharge and a serious attitude problem, they probably would’ve laughed in your face. But here we are. Tyler Green, played by the charismatic Ryan-James Hatanaka, has become one of the most polarizing figures in the Evolution era of the show.
Some fans love the edge he brings. Others? They can’t stand how he’s basically bypassed a decade of FBI training to sit at the big kids' table. Whether you're rooting for him or waiting for him to mess up, there’s no denying that Tyler Green has fundamentally changed the vibe of the series.
Who is Tyler Green, anyway?
When we first met Tyler in Criminal Minds: Evolution Season 16, he wasn't exactly "hero" material. He was a guy on a mission—a dark, obsessive, one-way mission.
His backstory is pretty tragic. His sister, Alison, went missing years ago, and Tyler spent a decade trying to find out what happened to her. He eventually realized she was a victim of Elias Voit (the terrifying "Sicarius"). To get close to the truth, Tyler did something insane: he infiltrated Voit's network of serial killers.
He wasn't a profiler. He was a former military intelligence officer who got kicked out of the service for leaked drone footage. He was a rogue actor, a hacker, and a man with nothing left to lose.
The transition from vigilante to agent
It’s been a wild ride watching him go from a guy the BAU was trying to stop to a guy the BAU actually employs. By the time Season 18 rolled around (which the show counts as Season 3 of Evolution), Tyler had officially joined the FBI as a rookie.
It’s a bit of a stretch, right?
In the real world, a dishonorable discharge and a history of hacking the government would usually land you in a federal prison, not a federal field office. But in the world of the BAU, his intimate knowledge of the Sicarius network made him "invaluable."
The Garcia of it all: A romance nobody asked for?
If you want to start a fight in a Criminal Minds Facebook group, just bring up Tyler Green and Penelope Garcia.
Their relationship was... complicated. Garcia is the heart of the team. She’s all about color, kindness, and "no-go" zones. Tyler is basically a walking shadow. When they first hooked up, it felt like a massive betrayal to many fans—especially the "Garvez" shippers who have been waiting years for Luke Alvez and Garcia to finally make it work.
- The Betrayal: Garcia broke her own rules for him. She was told to keep it professional, but she couldn't help herself.
- The Fallout: Their breakup was messy. It involved hospital visits, lies, and a lot of emotional baggage.
- The Current Vibe: In recent episodes, they've been trying to work together as colleagues. It's awkward. It's tense. And frankly, it’s a bit distracting when they're supposed to be catching monsters.
Is Tyler Green actually becoming a "Mini-Voit"?
This is the theory that’s currently keeping fans up at night. In Season 18 (Evolution Season 3), we’ve seen some cracks in Tyler’s "good guy" facade.
There was a particularly chilling moment in Episode 7 where Tyler lost his cool during an interrogation with Voit. He wasn't just angry; he was aggressive in a way that felt familiar. Even Tara Lewis noticed it and gave him a warning.
Voit has this way of getting under people's skin. He told Tyler that he "can't fake the darkness" he sees in him. It raises a massive question: Did Tyler spend so much time hunting a monster that he accidentally became one?
The Sister Connection
The show recently went back into the details of Alison’s murder. Voit admitted he targeted her because her "goodness" reminded him of his mother. He tried to "be normal" with her, but when that failed, he killed her.
Seeing Tyler confront the man who did that—while trying to maintain the professional standards of the FBI—is a recipe for disaster. He’s a powder keg. One wrong move from Voit, and Tyler might just finish the "one-way path" he started years ago.
Why fans are so split on his character
Let’s be real—the writing for Tyler is a bit "all over the place."
One minute he's a tech genius who rivals Garcia. The next, he's out in the field kicking down doors like he's been doing it for twenty years. Some viewers find it "ridiculous" that he’s allowed anywhere near the Voit investigation given his personal connection. In any real law enforcement agency, that’s a massive conflict of interest that would get a case thrown out of court.
But then there's the other side. Ryan-James Hatanaka brings a grounded, gritty energy that the show arguably needed. The BAU can sometimes feel like a group of superheroes who always know the answer. Tyler makes mistakes. He’s impulsive. He’s human.
What happens next?
If you're following the latest episodes, things are getting weird. The BAU is dealing with "Gold Star" and a new version of the Sicarius network.
Tyler is currently caught between two worlds. He wants to be a team player, but his instincts are those of a lone wolf. He’s trying to find his "niche" in the team, but as long as Elias Voit is breathing, Tyler’s focus is going to be divided.
Here is what you should watch for in upcoming episodes:
- The "Rookie" growing pains: Will Tyler actually follow orders, or will he go rogue again?
- The Alvez friction: The bromance/rivalry with Luke Alvez is one of the best parts of the new season. Watch for that tension to peak.
- The Breaking Point: Eventually, Tyler is going to have to choose between justice and revenge.
If you're catching up on the series, pay close attention to the scenes between Tyler and Prentiss. She sees the potential in him, but she also sees the danger. He’s a wild card in a game where the stakes are literally life and death.
To keep up with Tyler's arc, make sure you're watching the episodes in order on Paramount+. The nuances of his relationship with the team change almost weekly, and skipping an episode means missing the subtle ways Voit is trying to recruit him—not to his network, but to his way of thinking. Keep an eye on his interrogation style; if he starts sounding more like a predator than a profiler, we’ll know he’s finally crossed the line.
