In that .gif, Arce goes from genuine mongoloid to scary vampire to gay Mexican cowboy within the space of about 8 seconds.
Hell no he didn't, Arce is a one dimensional no skill hypejob, pretty much like his fellow Mexican buddy Margarito. The guy has over 50 fights and looked completely lost when Darch adapted, he was just stalking and getting wobbly doing so, it was hilarious.
