Dude saved Anakin from being a burn victim perma incel and turned him into a slayer too ngl. Vader's new legs gave him a few inches in height too (from 6'2 to 6'8). I legit remember a comic where he had a subordinate who was a foid glazing this dude vader hard for being dark triad.
In short, Palpatine saved this dude Anakin after he schizo'd out and killed his oneitis and got burnt to crisp.
