Swansea (Mouthwashing)

He (around 50 to 60 years old) was a heavy alcoholic that quit making it 15 years of not drinking. Before any of the Mouth washing events he actually had a happy life with a wife and kids but he feels life something is missing. He know where the freeze pods are but only one of the 5 made it and it's head canon that he saved it for Daisuke (Mouthwashing). Basically midway through the game they discover a bunch of mouth washing bottles and when he discovered that it had 14% ethanol he broke his 15 year streak and started to heavily drink again. He puts Daisuke (Mouthwashing) out of his misery when he gets severely injured (Swansea was completely drunk off mouth washing). He eventually gets shot in the head by Jimmy (Mouthwashing).

"My favorite character is Swansea (Mouthwashing)"
It probably is, but 50% of the fandom just likes him because he had a very good relationship (father and son type) with daisuke
