A great and little-used character is a villain named Brynocki, who was a villain in MASTER OF KUNG FU 33-35 by Moench, and Gulacy/Adkins in 1975.
Later re-aappearing in 72-75, by Moench, and Zeck/Patterson.
And one last appearance in issue 119 in Dec 1982, by Moench/Sylvestri.

He was a cute little Disney-looking robot servant of a character named Mordillo, who created robot killers, and Shang Chi follows the path back to a private island Mordillo owns, that's kind of like a Disney theme park of robots and death traps for Shang Chi and his friends. Brynocki is something of a caretaker for the island and its killer machinations, who is extremely loyal to Mordillo. Even beyond his master's death in subsequent stories, Brynocki continues to serve him.

While innocent-looking and prone to speaking in cheerful good-natured catch-phrases and playfully taking on different cliche roles and costumes, Brynocki is deadly dangerous. The paradoxes and ironies make him a very likeable and interesting character.




It was nice that he was handled exclusively for so long by Moench. Having only one writer gave him a consistency over multiple appearances.

He also had one appearance by Bill Mantlo and Sal Buscema in ROM 47 (another series I really enjoyed).

The only other appearance I'm aware of was in THE THING 1-3 (2006 series) by writer Dan Slott, with art by Andrea Devito.
