Mega Girl flew at top speeds towards the military compounds, leaving trails of smoke behind her. Her body broke through the air creating bangs from her supersonic speed. It felt good to be so powerful, though her large ass and breasts, perky in her 18 years of age, dampened her aerodynamics a bit.
“I can’t be true...!” She thought, with gritted teeth, as she made her way towards the base in the desert, where she found it to be completely destroyed. “No!” And all the superheroes who’d been summoned there, one by one, had been wrecked and destroyed. “What the ... how??”
Mega Girl was shocked and dismayed, but she didn’t need to wait a lot to see who the culprit of all that destruction was – and how powerful she truly was.
“What the fuck??”
Mega Girl stopped, hovering quietly in the air, and looked at what seemed to be a copy of herself a mile ahead.
A woman very similar to herself, more than a lookalike, almost a clone, rose from the ground while grabbing Tank Man in her hand.
Tank Man was a 10ft-tall, 6,000-pound muscled black man with iron and steel armor all over his formidable muscles.
He was bleeding and squirming as half of his armor had been peeled off and his bones showed through his wrecked and mangled limps.
The enemy grabbed him by the throat and slapped him for fun like a little bitch.
Blam!! Blam!! Boom!!
Mega Girl gulped, seeing the shock waves burst from the enemy’s palm every time she slapped the once formidable hero. “No...!”
When the enemy rose high enough, hovering at about the same height at Mega Girl, she stopped and looked at the newly arrived hero, and then the biggest, most sadistic smile grew on her face.
“Oh, look at who’s got here just in time!” She crushed Tank Man’s throat harder, making his legs kick and squirm in the air. “I was just getting tired of playing with these toys.” She tightened her grip further. Blood overflowed from Tank Man’s mouth. “How have you been, worm? Grown bigger since last time we met, I see.”
Mega Girl saw her looking at her breasts, which she quickly and reflexively covered with her arms, grunting and blushing. “You...!” She gritted her teeth and tried to look as fiery as she could, but next to that woman, she looked but like a little kitty; a fresher and softer version of her more mature being. “I beat you!”
“Yes, that’s quite right, but this was also a long, long time ago.”
“How did you escape??” She roared. “And what do you want this time?”
The enemy woman smirked, and then she tortured Tank Man further with her grip. The giant black bull used the last of his energies to kick her and punch her, but not an inch of her body moved, and even though shock waves came from his punches, the woman appeared to literally not notice what he was doing – something that sent a chill down Mega Girl’s spine.
“Last time, I was on a mission. My handlers were ... greatly suppressing my powers.” She spoke, and she made the bones of Tank Man’s throat crack as she instinctively crushed it. “This will no longer be a problem. You see, I killed them all. After you sent me back to that place, that prison...” She gritted her teeth, and for once, some expression other than cockiness graced her face. An expression of anger and hate. “They tried to put me on drugs, keep crushing me and suppressing my powers, but the thing is ... even they didn’t expect my powers to keep growing at that rate. Neither did I.”
Tank Man squirmed pathetically on her grip. His kicks and punches became weaker and weaker, and soon enough, he couldn’t even reach her body, which was so solid it was like a fixed point in space; not even the full blast of a supernova could move her an inch from where she was, it seemed.
“I felt my muscles getting denser. The fibers multiplying and weaving together, clustering in a way that my physical appearance didn’t change much – though I did grow taller and beefier, as you can see.”
She winked, and yes, Mega Girl could see that her rival was taller and more muscular than before, though not by an outrageous degree. Mega Girl herself had grown more, though she still remained a bit shorter and leaner than that woman.
That bitch.
That ... goddess.
“Power Woman!” She hissed through gritted teeth, then muttered more angrily the other name by which that bitch was known: “Galacta!”
The bitch smirked, and her fingers cracked more of Tank Man’s bones.
His limbs went limp. The final threads of his energy were leaving, dissolving...
“Aww, you remember.” She winked again. “Good. Save us time with introductions.”
Mega Girl gnarled like an angry bitch, and then she barked an order: “Let him go!”
“Oh? Who?” Galacta was legitimately confused, and only when she looked at her hand did she remember what she was doing and who she was torturing. “Oh, yes. This little thing.”
She cast him aside, threw him over her shoulder, like he was nothing.
Tank Man fell, fell, and fell, and his giant body crashed on a pile of hundreds of defeated superheroes.
Booom!!
Mega Girl gulped when she saw the mass of beaten heroes grow by another body. “Holy f-” This were almost all the heroes of the Super League, and at least a dozen of them had enough power individually to destroy the whole planet if they saw it fit. “Shit!”
Galacta clasped her hands, throwing off the dust, dirt, and blood that had gathered on them. “There. I was tired playing with him anyway.” She looked at Mega Girl and licked her fat, aggressively red lips. “I have grown a bit too powerful for my own good. I remember the time when a few dozen of these superheroes would have beaten me.” Her tone became graver, and her purrs angrier and more bitter. “You and your two other gal pals beat me. Puny little things!” She clicked her tongue. “I was mopping the floor with your face before those two heroes shows up, and I could have destroyed you all if my handlers hadn’t intervened.”
Mega Girl didn’t bother to respond. She was afraid.
Her heartbeat was rising and her blood was warming up. She assumed a defensive stance, raising her fists while also seeing them shaking – if just a tiny bit.
