Beast+ continues from where Beast left off, though it is marketed as a stand-alone series. Episodes are reduced to approximately ten minutes in length, airing in the thirty minute time-slot Oha Coliseum alongside the Saru Getchu anime. Beast+ consists of a string of arcs beginning with the appearance of the Professor and Zero (both from Mega Man Network Transmission).

"This Anime (Episode 2, to be exact), where Rockman travels from the Game-World to the real world, to learn some cultural differences about Japan, was intended to be a Special Episode for the original Mega Man Cartoon Series by Ruby-Spears, which aired around 1995 in the US. As it seems, the special was finished before Ruby-Spears decided to redo their whole show with a completely new design, better suited for American audiences. Thus, not fitting the new style anymore, it never was included in the series. Still, two more episodes about the same story were produced a bit later, this time under the main title "Rockman" (unlike Episode 2, where he's called Mega Man, even in the japanese dub). It's unknown if these 3 Episodes ever saw an official release, until 2002, when Capcom of Japan decided to finally (re)release them on DVD for Rockman's 15th Anniversary (all featuring a Japanese and English dub, but no subs). It's unknown if there are any more secret animated works of the original Rockman game-series."

Three hundred years ago, a genetic experiment gone wrong caused the mutation of all forests on Earth. Armed with consciousness, the vegetation sought to destroy all of humankind, and the war that ensued turned the planet into a hellish dystopia. In the present day, Agito, a young boy, lives with his father in Neutral City—a village maintaining an uneasy truce with the neighboring forest. One day, Agito, on his way to collect water, becomes separated from his friend and stumbles upon a relic of the past: a girl sleeping in a mysterious machine. Agito awakens the girl, Toola Cm Sacl, and introduces her to the village. But outside forces have ulterior motives for the girl, who holds the key to restore the Earth. Misguided by Shunack, a soldier from the old world hellbent on destroying the forest, Toola follows him despite Agito's warning. Determined to save Toola and unify humankind with the forest, Agito borrows the power of the forest and pursues her.
