The Caped Crusader and Hero of Gotham. Batman is a major character in this series, being Mario's guiding voice and best friend through this adventure. Batman is a dark and brooding hero with a strong sense of justice. In this series, Batman's personality can be summarized as a mix between Vegeta and Rick Sanches. Batman is stubborn, egotistical, and brash, but deep down he has a strong moral compass and is willing to do whatever it takes for the greater good. Batman is a tsundere

Voice:
For this production, I am looking for someone who can best capture the spirit of the character for this series, rather than mimicking a previous actor. You can use his previous voices as an inspiration, but I value performance over mimicry for this character. The actor must be able to distinguish between Bruce Wayne and Batman. 
Examples of his previous voices
More examples, this guy had a lot of actors.
His live action roles if you wanna use that as a springboard

Again, I want to emphasize that for Batman, I am not looking for an exact 1 to 1 copy of a previous voice. Make it your own but encompass who the character is
