So, I finally decide to show how Acid looked as a child. X3 I know, it's late! I actually drew this some time ago, but I decided that since I showed you how he looked as an adult and teen, I'll show this one.

This was before he used the tank or any other means of not killing people whenever he was just near. He would be sad when people choked to death when they inhaled the toxins, so naturally, just like with any other Dark Number, people started hating him and his older brother, the only member of his family since his mother and gather died of unknown causes. He eventually became numb to the despair caused by killing people unintentionally and by the people trying to kill him. When they had to move to a new place, his brother would transform into his beast form for transportation, and he would carry Acid on his shoulder.

And that's why Acid likes carrying people on his shoulder now XD
