He also began working for Desastre Total Ultraviolento (DTU) and Nueva Generation Xtrema (NGX), adopting a more hardcore style of wrestling that involved the use of weapons, tables, chair and ladders in the matches.

[6] The team held the title for nearly five months, although Halloween did not wrestled for part of that time, before losing the championship to La Hermandad 187 (Joe Líder and Nicho el Millonario) on September 14.

Tiger then participated in the 2008 Alas de Oro, but was unable to win the tournament for the second year in a row as he was eliminated as the second to last competitor, leaving only Jack Evans and 2008 winner Aero Star.

A few weeks later, at Triplemania XVII, Extreme Tiger won the Cruiserweight Title from Koslov in a multi-competitor match that also included Alan Stone and Crazy Boy.

Tiger won his second Cruiserweight Title by winning 5-man ladder match against Sugi San, Jack Evans, Rocky Romero and Teddy Hart.

[10] In subsequent months Alex Koslov has returned to AAA as part of La Legión Extranjera and continued to make challenges to Extreme Tiger, who managed to retain the title in all of their matches.

[13] Just three days later Extreme Tiger and Jack Evans defeated Los Maniacos (Silver King and Último Gladiador) to win the AAA World Tag Team Championship.

[14] Tiger and Evans made their first successful defense of the title on June 18 at Triplemanía XIX, defeating the TNA team of Abyss and Mr. Anderson in a steel cage match.

[16] On August 5, 2012, at Triplemanía XX, Tiger reunited with Halloween for one night to take part in a Parejas Suicidas steel cage match, featuring three other former tag teams.

[18][19] On October 15, 2010, Tiger made his Pro Wrestling Noah debut entering the Nippon TV Cup Junior Heavyweight Tag League teaming with Jack Evans.

[26] As a result, the two received a shot at the World Tag Team Championship the following week, but were defeated in a three-way match, which also included The Wolves (Davey Richards and Eddie Edwards).

[29] On the May 15 episode of Impact Wrestling, Uno faced Sanada and DJ Zema in a triple threat match for the X Division Championship but failed to win the title.

[30] On the August 27 episode of Impact Wrestling, Uno, Low Ki and Crazzy Steve defeated Homicide, DJZ, and Manik in a six-man tag team match.

Uno would then compete in a four-way match for the vacant X Division Championship on the November 19 episode of Impact Wrestling, which Low Ki won.

On the June 24 episode of Impact Wrestling, Uno competed in the three-way elimination tournament final, in which he defeated Low Ki and Grado to capture his first X Division Championship.
