Ep. 21: Vega menggunakan OOParts untuk menghidupkan kembali Le Mu sementara Lyra Note dan Rogue bertarung melawan musuh masing-masing.

21

Vega revives Le Mu using the OOParts while Lyra Note confronts Dark Phantom and Yeti Blizzard. Rogue takes on Hollow and holds him off for a while. Geo sees that Omega-Xis is being smothered in a pool of dangerous substance. He then jumps down to save him and rises back up in his EM form. Copper shouts out to Mega Man to grab the OOParts before Le Mu comes to life. He grabs them all and Mega Man transforms into the ultimate amalgamation of all three OOParts: Tribe King. Using this new power, Mega Man destroys Hollow, but Vega escapes arrest. As everyone escapes Mu, Rogue appears and uses what's left of his energy, with the help of Tribe King Mega Man, to seal Le Mu and close the portal to Mu with Vega still inside. With disaster averted, life goes back to normal for Geo and his friends. (Source: Wikipedia)
