4) The Logo
It’s a shame that Marvel decided to show The Punisher’s final costume in promo material, because seeing Frank putting it together is a great moment. It may be as simple as the vigilante just spray painting his body armour with the skull logo, which has become synonymous with his story after him being shot in the head was well publicized during the trial, but finally seeing Frank become The Punisher we all know from the comics is very satisfying indeed.
By the time the season comes to an end, it’s clear that his transformation is now complete, something this logo signifies.
