3. General Grievous
As a fan, it pains me to put General Grievous on the list, but he does not make the cut. COVID-19 will still be raging across the country come December, and while he may not be contagious, Grievous’ cough is bound to make your guests uncomfortable.
He is also well-known for his pure ruthlessness, the Jedi hunter with the weapons of fallen Jedi knights in his pockets. He would be a dangerous participant in a game of Hide and Seek. His hatred of the Jedi may also cause him to ruffle some feathers with your other guests, assuming they come from the Star Wars universe.
Grievous is especially dangerous too because of the skills he possesses. His cybernetic construction makes him quick and strong, while he also shows an acute level of military strategy. His successful capture of Chancellor Palpatine over the Republic stronghold Coruscant is a prime example of that.
I would be a bit afraid if Grievous were at my house, and I think you’d be too.
