Chapter Text
Katsuki stood up to their full towering height. A bit higher than their usual form. The height was the only similarity to the shape they usually took for vigilante activities though. Katsuki dropped off the building and hit the ground with a thud.
Their usual soundless steps hit with a muffled thump with each long stride. People all around them froze as they neared. Most started backing away, a few started screaming and even fewer pulled out their phones to take pictures.
“Idiots!” Katsuki snarled to Deku.
He lifted their hands up into the air and let off some explosions to scare off any lingering civilians. They ran off screaming from their monstrous form. Katsuki guessed they were eight feet tall tall with eight arms, six on the front and two on the back. They had forgone a head to aid in their plan. Katsuki stomped up to Muscular who turned around and began laughing.
“Come to fight me again Gestalt?’ he taunted.
Katsuki took a few steps closer. Once he was in range he began firing off explosions and swinging their arms around to warm up. Muscular laughed derisively at his display. Right as he opened his mouth to speak again, time slowed in Katsuki’s perception. His vision narrowed down on Muscualar’s mouth.
The air was filled with a disgusting hawking noise and then Katsuki spat a loogie of slime right at Muscular’s ugly face. The villain didn't even notice the clear glob of slime flying through the air too preoccupied by their massive anti Muscular form dissolving, just as they had planned.
The loogie holding their consciences land squarely in Muscular’s mouth. Katsuki wasted no time in crawling blindly down his oesophagus and creating more slime in his lungs. Muscular’s super powered coughing was almost too much but finally the villain passed out from oxygen loss.
They crawled out of his mouth and formed a tiny clear version of Gestalt. When Eraserhead arrived on the scene all he could see was Muscular unconscious, a massive pile of goo, and them standing proudly upon their conquered foe.
