Background information
Brass's last name likely comes from the term used for for police officers.

Brass can safely be assumed to now be dead or somehow indisposed due to the introduction of Commander Abraham Tower. Writer Ian Flynn himself stated that he planned to reveal that Brass had been killed during Sonic's year long absence, only for someone else to point out that Brass was present after Sonic's return. ,
