Tropes Associated With Jessie James Grelle:
- Determinator: Some of their best known roles fall into this category. Kenichi Shirahama, Akihisa Yoshii, Yuuji Sakai, Kazuya Aoi, and Yukiteru Amano are some of the top examples in the list.
- Harem Genre: A lot of their roles happen to be protagonists of this trope, so much so fans have nicknamed them the "Harem King". Stand-out examples include Shido Itsuka, Issei Hyoudou, Fuutarou Uesugi, Ichika Orimura and Touya Mochizuki.
- Man of a Thousand Voices: Their vocal range is very wide in spite of the younger-sounding voice they use for their protagonist roles. Their voice can break deep whenever they need to tackle an adult character, The Stoic, or a more villainous character. They are also capable of voicing accents such as Lithuania with a stereotypical accent in Hetalia: Axis Powers; and their voice is androgynous enough to voice crossdressing characters (such as Kuranosuke Koibuchi)
- Pigeonholed Voice Actor: They're pretty much the go to guy for the young protagonist role in any anime series when it comes down to Funimation and Sentai Filmworks of various types from Butt-Monkey/Unlucky Everydude to a harem protagonist, Nice Guy, and Kid Hero alike. Regardless of the character's personality, expect them to be The Determinator via default or Character Development. However, their vocal range is relatively flexible and can play other characters if necessary as seen above.
- Playing Against Type: Akira Amamiyaspoiler , Akira Agarkar Yamadanote , and Tomohiko Kazami spoiler . Not only that, these roles are the roles where they use a deeper voice for those characters. They also voiced Akasha Shishidou, who happens to be a villain. In RWBY, they voice the Axe-Crazy Giggling Villain Tyrian. According to their Twitter, they're actually enjoying playing this (in their own words) 'psycho' role.
