The toxic valley could use some more activity; why not a behmonth nuke boss?

People have requested a super mutant behmonth boss fight for quite awhile, and I personally think that this could work as the toxic valley’s nuke boss.

Have the story be that one of Dr. Blackburn’s last subjects escaped to a location in the toxic valley to hide, stayed reasonably intelligent and went mad as they became a behmonth. Have them use mininukes instead of the stones behmonths normally throw, Blackburn’s poison AoE stomp, the fodder for the fight be other ‘insane’ super mutants (beserkers and suiciders), give the boss a similar appearance to Blackburn during his fight and a fitting melee weapon for the location (I have no idea where this could be done; a mine or perhaps some lab would need to be added to be opened by the nuke, and a reason to even do this), and we’d be set.

Rewards would be themed around wherever we fight them, alongside a unique fat man (skin and name + special effects) and some fitting melee weapon.
