ウルティモ・ゲレーロ
Many sources mistakenly list Hooligan and Ephesto as brothers of José Gutiérrez but they are not blood relatives. Gutiérrez, Ephesto, and Hooligan trained together and became close friends leading to often referring to each other as "brother" without having any blood relationship. Hooligan and Ephesto are brothers which is why Ephesto is sometimes mistaken for Gutiérrez's brother as well. In 2008 Último Guerrero introduced "Último Guerrero, Jr." to the wrestling world. While it is not uncommon for fake relatives to be promoted in Lucha Libre it is believed that Último Guerrero Jr. is indeed the son of Último Guerrero. Later on Guerrero Jr. would be reintroduced as Gran Guerrero, with the storyline explanation being that Gran Guerrero was the much younger brother of Último Guerrero.
