S1·E31 Star Force!

Mega Man battles with the FM-ians and uses Star Force forms Ice Pegasus, Fire Leo, and Green Dragon to succeed. Gemini Spark also appears, attempting to steal the Andromeda Key from Cygnus Wing, but an Atomic Blazer attack from Mega Man both destroys Cygnus (freeing Tom) and causes Gemini Spark to flee. Omega-Xis proceeds to smash the key before the two return home, only for Pat to find it in the rubble.
