I hope this clears up any of your final concerns/questions. [@BlackSam3091]

1. I was hoping to keep the mask since it also gave me the idea for the name Inkblot. For why the gang had it my explanation is they took it from a man who couldn't pay up and was also a tailor who made the boss and gang members some new outfits as well handing over the mask, and when Matt looked at it he knew that their were heroes out there trying to save people and stop bad guys but they mostly focus on bigger ones and not so much the littler ones. Which gave Matt the idea to become his own hero and take on the smaller potion of bad guys that most heros don't do anything about.

2. Matt in actuality took on a total of five guys in total three at the front he punched one broke another ones hand and knocked one out with a baseball bat. Inside he took one out who had a gun pointed at his back, but was able to obtain said gun. Then Matt took on the boss of the gang any others were just there and he basically scared them off when they ran out of ammo and he had a loaded gun. It is also implied that since Matt lives in such a bad place he had to have some sort of basic grasps of self defense and worked out quite a bit since it wasn't just him he was protecting but also his mother as well.

3. I was mostly trying to explain if a person who witnessed Matt fighting crime they first would say "a man wearing a mask with an inkblot on it.
