On December 9, 2006, González dropped the title to Sewell, prompting a heel turn and a rivalry between them. After Sewell won three straight contests, including a rematch for the title, he was disqualified in a special challenge against Bison Smith. The following day he won the World Heavyweight Championship and formed a partnership with Smith. However, Sewell won all of the tag team matches between them while his partner, Banderas, defeated González one on one. Depots this run, he retained the title in a rubber match held on February 3, 2007. González then teamed with Judas and reunited with "Lightning" Cruz winning two out of three appearances over the face stable. However, Vega's reappearance earned Sewell and Banderas the upper hand, going on to win a 3-on-3 match, while another was ruled a no contest. On February 24, 2007, González participated in an over-the-top battle royal, won by Sewell, who also won a tag team match between them in his next appearance. The following month, he was involved in a feud against Thunder and Lightning, losing to both in singles matches and a tag team contest. On March 23, 2007, González defeated Pérez, which was followed by two more matches against Los Autenticos, which his team lost in a six-on-six. González also defended the IWA World Heavyweight Championship against Billy Kidman and Joe Bravo. Following a hiatus, González made his return to the IWA on December 15, 2007, participating on the Christmas in PR event. At Histeria Boricua 2008, he returned by teaming with Figueroa to defeat Los Autenticos. In February 2008, González formed a tag team with Cotto, which was quickly dissolved when he turned heel following two losses. He won two consecutive matches, before fading from IWA programming.
