There is zero fucking overlap between Devitt/Balor and McGregor apart from being Irish.
They have nothing in common in character, promos, style, clothes...
Balor comes out in face paint as a demon, McGregor wears bespoke suits.
Balor is a humble guy that all his colleagues love, McGregor is an asshole.
Balor cuts a promo about how good his opponent is but he's going down, McGregor calls his opponents bums.
Balor has brown hair, McGregor is ginger.
Balor can legit wrestle, McGregor can't.
Balor is a legit black belt submission grappler, McGregor is a panic wrestler.
