Edgar Swann

Swan is a legendary boss living in Swan's Pond, the center of the Boston Common in 2287.

Don't let the name fool you: Swan is a gigantic super mutant behemoth and about as ungraceful as they come. He rises from the Boston Common pond to squash anything that comes too close or makes the mistake of shooting the thick armored shell he fashioned for himself out of fragments of swan boats.

Background
His story is a tragic one: Rather than a random monster, Swan was once Edgar Swann, a low level Institute worker who found himself on the wrong end of the law after stealing a couple of cigars. This all occurred around 2178 as the Institute was first developing its organic slave race. During the trial, he was offered a choice of participating in the FEV experiments that just started. Originally presented as "probation", Edgar was provided with food, water, shelter, and infected with the Institute's own strain of FEV. Within six days, his body began to remake itself, leading to constant ache and disorganized thoughts as the strain forced the changes.

Two weeks later, the evolution stabilized, with a threefold increase in muscle mass and major increase in intellectual capacity: In short, a full success. Swann even applied to the research team, to continue the experiment himself. Unfortunately, the fundamentally unstable nature of the strain led to his mental capacity peaking 19 days from infection and started to rapidly deteriorate by the 21st, manifesting alongside repeated seizures and a sudden destabilization of his mutations. With a poor prognosis, Swann's fears of being dumped to the Commonwealth eventually realized as he was ejected onto the surface, having mysteriously retained the experiment logs.

After his expulsion and abandonment, Swann eventually made his way to Boston Common, an abandoned park in the downtown ruins, where he made his home in the groundskeeper shack. It was here he finally lost his mind to his mutation, eventually creating armor from the swan boats of the pond and developed into a behemoth.

It was only after his arrival that the Common became a place not only to be avoided at all costs, but to be fundamentally feared. The bodies of countless victims who did not heed the warnings are strewn about the Common.
