Brother Band - S1.E51

Working with Lyra Note, Mega Man battles the FM-ians as they attack Echo Ridge. Amidst the battle, the Andromeda Key is broken, and all of the gathered minus energy is lost. Then, the FM-ians' king sends a signal to his soldiers telling them to withdraw from their attacks on Earth. Aaron suspects that Kelvin used Brother Band to convince the FM Planet that Earth is not hostile. However, Pat is not content with withdrawing from Earth, so as Gemini Spark, he murders Taurus one night and harnesses his body as energy for a new Andromeda Key.
