This is an episode of the series Evfnye 10.Cosmic Brain Part 4: Rewarded is the fortieth and last episode of Evfnye 10.
As Evfnye as Brainstorm is held in place by both Neuroticus and Synapse, he doesn't know how to react, and Nicky and Jerry have no ideas either. Everything seems lost, but a portal appears and an unknown alien appears in front of the Cerebrocrustaceans, which turns out to be Evfnye 10,000 as Chromastone, who absorbs their electric impulses. He tells his confused present counterpart to activate "Master Control". Brainstorm hides while Nicky fights SupresLime and Jerry deals with Synapse. Brainstorm takes his time and hacks the 9th Omnitrix. After a while, he succeeds and turns into XLR8 to go fight everyone. He confuses the enemies and truns into Crabclaw, while his future version uses Eye Guy to deal with SupresLime. After some pure fight, both Evfnyes use their respective Wildvine to tangle Synapse. Present Evfnye believes that enough is enough, and turns into Brainstorm again, but Evfnye 10,000 turns into Upgrade and boosts his powers. In this formation, Brainstorm defeats the trinity of villains, later bringing them into a speed-built interstellar spaceship, which will bring them back to the Incarcecon. Evfnye 10,000 somehow disappears.
At the end, Ketu (who was in the space station) thanks Evfnye for defeating Neuroticus, but makes him acknowledge that he might need more planning for the future. Evfnye hardly understands, and Nicky reminds everyone that Earth is no longer under virus, and can now be accessed. Evfnye says goodbye to Nicky and Jerry and flies on Earth, while these two remain in the space station. As he lands, he deactivates his Omnitrix after quickly using all of his transformations for one last time, thinking he had enough of this. Then he exited in an unknown temperate place. He looked around and saw something that changed his life once again...
