is an Ecuadorian professional wrestler. He is perhaps best known for his appearances in the United States throughout the 1990s, including stints with Extreme Championship Wrestling under his birth name and under the ring names El Puerto Riqueño and Ubas and with the World Wrestling Federation as Babu Pablo Márquez was briefly part of the WWF's fledgeling Light Heavyweight division, wrestling two matches against Taka Michinoku in late 1997 and early 1998. He re-debuted on the August 16, 1998 episode of Sunday Night Heat under the name of "Abu" (later "Babu"). His gimmick was that of a manservant to Tiger Ali Singh. He was often seen doing degrading things for Singh. Although most of his stint in WWF was in a non-wrestling role, he did have a few televised matches: on the November 3, 1998 edition of Monday Night Raw, he was ordered by Tiger Ali Singh to wrestle Al Snow, though Singh reentered and won the match; on the December 6, 1998 edition of WWE Sunday Night Heat, he teamed with Singh to wrestle Kurrgan and Luna Vachon, with the match ending in a no-contest. He also wrestled on a 1998 edition of Shotgun when he was ordered by Singh to compete against Goldust in a losing effort.
