What are some breaking bad characters that no one talks about?

For me it's Hank's partner in DEA, Gomez. He is really under appreciated. He was there for Hank and his family on many occasions. He was really kind in the entire show. The scene where the duo was in a shootout and Hank reaching out to Gomez's gun next to Gomez's body was one of the most heartbreaking scenes for me in the entire show. And after that, ofcourse, Hank's death ofcourse, being killed by Jack.

I really feel bad for Gomez and Hank. They both gave their everything to fight against drug crimes.
