The first and so far only champion is Místico, who was under contract with Consejo Mundial de Lucha Libre (CMLL) at the time, but worked for IWRG under a talent sharing agreement between the two companies.[2] The talent sharing agreement ended in 2008, but the Super Welterweight Championship has not officially been declared vacant even. It is considered inactive as the IWRG simply does not promote it or refer to it any more.

^One example the weightlimits not being strictly enforced is Mephisto winning the CMLL World Welterweight Championship, a championship with a 78 kg (172 lb) upper limit despite weighing 90 kg (200 lb).
^It is not clear exactly when in 2007 IWRG and CMLL stopped working together, making the length of Místico's reign too uncertain to calculate.
