Mercer is an A Rank Mercenary for the Pantheon organization, he was permanently blinded due to his skills, but his senses became heightened 10 times, keeping him incredibly useful as a mercenary. He's just a father doing his job to protect his kids.

His voice range is of Wolfwood from Trigun (Maybe a tad deeper in pitch if you can, and more intimidating. But it's okay if not) ((AABBCC FORMAT PLEASE))
