Today’s weird Marvel villain is Baron Gothenvald, created by @jeffparker and Kev Walker in 2011’s Thunderbolts #156!
In 1911, the occultist Baron Gothenvald and his entire Mignola-y castle disappeared, just as they were about to be sacked - but now they’ve reappeared in modern-day Stuttgart, and the Thunderbolts are on the case!
Gothenvald has seen enough, though, and retreats from this plane of existence, vowing to return to seek his vengeance!
