I’m probably alone in it, but Fiend and Fiendette get my vote.
OC is an inoffensive comedy gimmick that, for the most part, stays away from the major storylines.
The Fiend somehow got progressively worse the longer it went on and exposed a major problem in Bray’s handling of the gimmick. He had the concept down, but the execution (like all his previous gimmicks and ideas) was choppy and fell apart once it came time to wrestle. Like I get that your character is this nigh invulnerable monster, but literally popping up after a finisher without bothering to sell it? Even Taker at least gave you a hope spot before sitting up like he’s rising from the grave.
