everything had a counterpart. heroes were the counterpart to villains, the grinch was the counterpart of santa, and in this case, you were the vessel of the counterpart of venom.
you had full control over the symbiote since it was completely mindless. that doesn’t mean you was going to do good things. after all, you were a villain.
using the abilities that came with the anti-venom, you created chaos and madness in your city. katsuki, being the hero he was, obviously had to put a stop to your madness and since he housed venom in his body, he could make it through to you.
it was late at night and you just destroyed buildings, attacking anyone who came in your vicinity. katsuki quickly came, seeing that you were in your symbiote form.
“what do you gain out of this, villain?!” katsuki yelled out, making you turn around. he was in his own symbiote form, the inky black liquid hiding his real identity from you and the world. he was holding onto a pole as he looked at you, ready to swing down and attack you if needed.
