I saw this same guy around a week ago, I was playing heisei and this random goober pops up out of nowhere. I genuinely thought that they were a developer for the K.A but I checked on the leaderbored and he had around 100-150 kills and that was all the information I needed and I got out of there. Btw I did pretty good against them to, I knocked off around a quarter of his health but I got my teeth kicked in :/
