All merging clubs have brought a piece of their old identity into the new formed club: from Atlético Cuernavaca were taken the name to the new club (although its name is also identical with former Atlético Español), from Celeste de Celaya were taken their light blue colors and from Atlético Español the mascot, the bull, which has also given the new team their nickname toros (bulls).

Atlético Celaya has taken the second-division position of their predecessors and has immediately reached the top-level.

First, they could win their group and in the play-offs they could make their way up to the finals in which they lost only due to the away-goal-rule after playing 1–1 and 0–0 with Necaxa.

They had also financial problems which led to the sale of their first-division-license to an industrialist from Morelos in winter 2002–03.

He formed a new team with the name Colibríes de Morelos but it disappeared as fast as it once appeared.
