In Sonic Racing Crossworlds, in a Grand Prix, Rivals will interact with each other through voice lines but the DLC characters don't have voices, thus no interactions with the main cast.

This also means the "item hit interactions" mid-race don't exist either.

What I am looking for are examples that you can recreate these characters' voices through their games/shows as faithfully as possible to original source material.

For Dr.Eggman, I'm looking for a voice that matches the in-game version of Sonic Crossworlds

"Example lines" can be custom made up by yourself or chosen from different media that the characters make appearances in! (For the base cast, use the main game's voices as reference)
