Jorge "Granpapi" Rivera is the supervillain grandfather of Manny Rivera, and father of Rodolfo Rivera. Outside of his mech-suit, Granpapi is the rich owner of the Rivera's apartment and commonly uses his greed to get money and make himself even richer. He acts as a bad influence on Manny, introducing the boy into the perks and fun of being a super villain. This always leads to conflicts with his son Rodolfo, who wants Manny to become a super hero.
Granpapi usually appears in all-black clothes with suspenders. He also commonly wears his Golden Sombrero of Chaos. He has white hair and a white mustache, as well as gray-colored stubble and yellow glasses.
Before the series, Granpapi was a diabolical supervillain in his day. It is unknown exactly what kind of crimes he commited, but he proved almost invincible and unapprehendable to most superheroes. The only one who could actually catch up to him and defeat him was his own son Rodolfo as his super hero alter ego White Pantera. He at one time had a relationship with Lady Gobbler that went as far as to almost marry her (which was probably the longest relationship between a Rivera and an Aves), but he broke her heart at the wedding church by riding off with another woman (who would eventually become Manny's grandmother and Rodolfo's mother) on horseback. Later on, he bought a top floor apartment where he, Rodolfo, and Manny currently live in, which prevents his son from being able to kick him out and stop being a bad influence to Manny.
According to Jorge, while Manny attends high school, he'll either pass away or move to a retirement home outside of Miracle City.
In reference to the creator's past, Granpapi is naturally based on Jorge Gutierrez's own grandfather, who was a military general. Jorge considered being in the military as evil, and was asked as a child by many people if he was going to be an artist like his father or a general like his grandfather.
