and the mc kinda made the lizard his slave (?) to fight some other monster in the swamp
Was it a manga or a webcomic? Can you give any physical description of the MC or anything else about the story?

This the only thing on the "lizard man" tag
afaik it's a manhwa and that's all that I really remember, I'm so sorry ( ･﹏･)
OH AND THE LIZARD WAS ACTUALLY CALLED A LIZARD WARRIOR OR SOMETHING LIKE THAT. but then the mc fought it and then made it his partner (?) to fight other monster
do any of u know this particular story where the main character (a guy) went to a swamp and fought a lizard guy (?)
