Jorge Rivera Soriano (born September 2, 1964)[1] is a Mexican luchador (Spanish for "professional wrestler") who is best known as a trainer.

As El Seminarista, he won a Luchas de Apuestas (bet match) against a young Super Crazy for his mask.

Peña later got sued by Mattel and decided to re-gimmick all of those who were in Power Raider to Los Cadetes Del Espacio.

In 1999 he worked between Asistencia Asesoría y Administración, Consejo Mundial de Lucha Libre, and International Wrestling Revolution Group as "Electra".

Rivera was scheduled to enter the 2010 King of Trios tournament, teaming with El Valiente and Turbo, but after he reportedly tried to hold the company up for more money, while failing to deliver Valiente and Turbo, Chikara announced that they were severing ties with him effective immediately.
