Her codename is Welsh for "melting fountain (which is also her Chinese name)," although it is incorrectly rendered. The correct rendition is toddiffons.
Her real name, Arianrhod Blodeuwedd, refers to twofigures in the Welsh mythology.
Toddifons has the traits of Y Ddraig Goch, or the Welsh Dragon. A draconic being that resembles Y Ddraig Goch is present in Toddifons' Elite 2 artwork.
Because her Signal Arrow and Fiery Instincts give her advantages against Sarkaz enemies, Toddifons had jokingly been called a racist by the Arknights community.
