The voice of a weary, but determined, old gentleman echoed through a dimly lit laboratory, as a single spotlight alit upon a large, metal operating table at the room's center. "This is Doctor Thomas Light; the year is 20XX. Today, I attempt to reactivate Buster Girl, otherwise known as model # DDN-001; she is a sophisticated humanoid robot created and later abandoned by my assistant, Dr. Dolly. Despite her unfinished nature, she may be our last, best chance to save the free world from my former associate's schemes. All power has been redirected into the robot's plasmatic battery. Reinitializing wake-up sequence in 3... 2... 1..."

Doctor Light pulled a large lever, surging the laboratory's main generator in an attempt to reactivate the prototype android. The girlish figure on the operating table began to twitch. The good doctor-- large, portly, with wooly hair whitened by age-- dwarfed this small robot; it was hard for him to believe how much was riding on those slim shoulders of hers. He couldn't risk jolting in any more energy without running the risk of frying her circuitry. He'd have to pray that the boot-up sequence would be successful...

Finally, blessedly, the robot opened her clear blue eyes and began to observe the room around her, although she barely turned her head to do so. Doctor Light's voice trembled, sounding twenty years younger. "A success! Buster Girl, are you awake?" he questioned. "Please, answer me if you can. How are you feeling?"

"I feel... I feel..." The girl didn't look more than around 18 years of age, a vulnerable blond with her hair in two pigtails. Her outfit, a half sky-blue, half-dark leotard covering just from her impressive chest down to her groin, with a tall vertical cut to the hips, seemed at odds with her mission to save the world. Besides that, all she wore were over-sized gloves and boots; she didn't even have the benefit of a helmet fitted for her.

He wondered if she felt confused... vulnerable... perhaps frightened. "Yes? You feel?"

"... Horny. For girls!" The girl's eyes lit up with excitement. Suddenly, she remembered what she'd been programmed for: fucking other girl robots!

"... Th-That does line up with what I remember of Dolly," Doctor Light sighed, rubbing his chin thoughtfully. "Buster Girl, I feel we should take this slowly. I have a more important task for you, but it may take the rest of the morning to catch you up. Please, sit upright if you can, and I'll begin the lessons immediately..."

Buster Girl learned first her own history: she'd been created by the brilliant scientist, Delila Dolly, an apprentice of Doctor Light's, along with several other robots. She had been a prototype; although Doctor Light never knew her function, he could now hazard a guess. She alone had been given a strange armament... a so-called "Girl Buster." At first, it appeared to be just a thick cylinder with a battery gauge running up one side and an opening on one end, but when slotted with two large batteries at its base-- a bit like the barrel of a tommy gun-- its shape became clear. It had quite clearly been designed to look like a penis. Investigating that weapon had brought two revelations to Doctor Light.

The first: that Dolly had created this robot with the intention of it fucking her other robots. This "weapon" was actually nothing more than a tool designed to sexually pleasure Dolly's other robots. All of this had been in the service of her own lesbian tendancies.

The second: that bizarrely enough, the sex toy Buster Girl was armed with could be modified to mimic the capabilities of Mega Man's own armaments. Essentially, it would be able to fire a precise burst of plasma, releasing in either rapid bursts or a stronger charged shot with appropriate timing. When he told all of this to Buster Girl, she raised her eyebrows in confusion.

"Why would I want to fight, Thomas?"

"Please, call me Dr. Light," the man coughed, then pointed to the dimly lit monitor of a huge console behind him. Upon it, eight pictures appeared: different environments, set ablaze or simply smashed to ruin, by shadowy figures barely caught on camera. "Dolly is vying to take over the world just as Wily once did using her own eight Robot Mistresses. Those robots of hers have caused no shortage of destruction and pain to humanity already. That fool, Wily... he believed her when she said she'd bail him out of prison in exchange for his knowledge on weapons systems. Instead, she left him to stew, then used the secrets she'd gained to modify her own robots. We now face a second coming of the strongest mechanoids Wily has ever created, this time under the menacing control of my former apprentice... Each of them is equipped with tools as powerful as those used by the original Robot Masters."

Buster Girl contemplated the situation. "But... Why do they fight for him?"

"The Robot Mistresses were each peaceful creations upon their inception. I was happy to assist Dolly with their construction, thinking they'd be used to benefit mankind. Little did I realize, each robot had been modified with a trigger; all Dolly needed was a single instruction to cause each of them to turn against their better natures and fight humanity. They even ambushed Mega Man and destroyed much of my laboratory... Mega Man was banged up badly during the fight and is currently in the repair bay. We can't wait for those repairs to finish, especially with my laboratory on limited power. It will be up to you to defeat Dolly's minions yourself. You're likely to find them confused and disoriented. Unfortunately, you'll have to battle them and enrage them further; I don't know what type of personalities we will see from them, but it's important that you disable them through combat so that you have your chance to deactivate them using your powered up Girl Buster-"

The girl smiled, then raised her hand. "I remember this one! I stick the Girl Buster in their pussy or their butt, right? There's a secret failsafe in there. If you hit it with the Girl Buster, it'll overload them and deactivate them, right?"

"... Exactly," Doctor Light smiled, secretly happy that she'd said it so he didn't have to. "It's an odd way to go about things, but if you can do this and bring them back to me, I can rewire the Robot Mistresses to regain their sanity."

"I can't wait to get started and fuck all of them! To rescue all of them, that is!" Buster Girl announced, jumping up from the bench and pressing her fists to her hips. That beaming, chipper exterior of hers belay a girl who was nearly as chipper about the idea of lending humanity a helping hand as she was sticking her "Girl Buster" into a collection of sexy lady robots. Once she climbed to her feet, however, her smile fell to a confused frown; she looked over her front, then over her shoulder at her back. For a moment, Doctor Light thought she must be planning to request more armor. "Um... Hey, Doctor Light? I think something's missing. Where is the Girl Buster?"

The Doctor muttered to himself awkwardly for a moment, then presented the phallic looking weapon. "About that... It seems it has two methods of usage. The first is handheld, used like any other weapon. The second is, ehm, to install it just beneath your leotard, right at your pelvic area. I thought that might be a bit of a personal matter for you, so... I wanted to consult you before I made any changes."

The girl closed her eyes with a sweet, gentle smile, then nodded her head, bobbing her blond pigtails. "I can tell you're a kind person, Doctor Light, not like my creator... That's all the more reason to help you. Don't worry about me; I've already made my decision!"
