Billy Ray Leung in Wicked Game, a live-action buddy-heist B-movie with fellow Power Rangers star Jason Narvy (Skull of Bulk and Skull), which mostly served to show off his martial arts and stunt skills.
Tohru Adachi and the Protagonist, Yu Narukami, in Persona 4, Persona 4: The Animation, and Persona 4 Arena. The Protagonist is just a Heroic Mime in Persona 4 and in the few instances in which he speaks, he sounds more like a Power Ranger (he calls out almost every Persona like he's saying "IT'S MORPHING TIME!"). Though in Arena, he's a mime no longer and sounds quite a fair bit like Adachi. To try and fix this, Adachi sounds much raspier in The Animation while Yu sounds more neutral.
Johnny was the English voice of Daisuke Ono after the two shared the role of Itsuki.
Crossdressing Voices: Averted. Some of the younger boy roles Johnny Yong Bosch gets happens to be voiced by a woman in the Japanese dub. In fact, the youngest character he has voiced in anime is Guren Nash from Tenkai Knights (who happens to be 11-years-old).
Dumb Is Good: If his character is good, he's generally not that intellegent. If his character is smart, he's generally not very good.
Ichigo Kurosaki is an interesting aversion to this trope, because while he's got the Leeroy Jenkins thing down, he's actually quite intelligent, both in school and in battle. This totally applies to Ichigo's Superpowered Evil Side, though.
Yu Narukami is a complete aversion. Not only is he very smart and resourceful in battle and school, he's also the main hero. Or it's possible said smarts come from eating stuff out of the fridge.
Full-Name Basis: A lot of people say his full name when talking about him. Even on this wiki.
One exception was in the first few episodes of Power Rangers where he was introduced, when he was credited under John Bosch.
Hey, It's That Voice!: Since his vocal range is limited due to typecasting, his voice acting is easily the most recognizable by many fans, even when he is supposed to be playing against the type.
Subverted with the title character from Soul Eater, he was misattributed to this character before it was later announced that the newcomer Micah Solusod is voicing Soul. * It also didn't help to note the fact that Johnny worked with Funimation on several titles in the past. Justified, as he was raised in a town in Texas during his childhood years where it is located near Funimation's headquarters
His performance as Sanada Yukimura was highly praised for his dedication in screaming just about every single line at the top of his lungs.
Let's just say that hamminess is part of his blood.
Not Even Bothering with the Accent: While he's capable of pulling off a high-pitch voice like Renton Thurston, he has yet played any role that involves pulling off an accent. That was until:
He has spoken in a completely different language in a dub - Being Izaya's voice actor required him to speak in Russian for a few lines. It sounds near perfect compared to Izaya's original voice.
Similarly, while still easily recognizable, he also attempted a Japanese accent in Binary Domain as Kurosawa. Seeing that he had worked a lot of anime titles in the past, it's no surprise he manage to pick this accent up quickly.
Perishing Alt Rock Voice: Johnny sings this way pretty often, probably because his voice has gone raspy from all his yelling he's done in anime voices.
Revolving Door Band: While Eyeshine has some fame, the band is not a full time gig for any of its members. As such many members have had to leave to focus on their careers or left for personal reasons. The band has gone through many guitarists and bassists.
Studio Chatter: Done at the beginning of "Blackout" on Red Stripes White Lights.
Team Dad: Crossing over with Papa Wolf, Johnny is definitely this. He takes very good care of his bandmates and will shed his normally easygoing demeanor if a situation could effect them or the band negatively.
