Indeed. Concurrently, the most fitting DQ class could be the Gladiator, which retains the combined strength of the Warrior and DQ's Monk, the Martial Artist with its signature skills like Hatchet Man and Boulder Toss. While the Monk and Martial Artist are powerful and speedy, the Gladiator has low agility, but with added power and double-or-nothing abilities like the aforementioned. Now, in classless DQ, we resort to the Hela Hammer for double-or-nothing power which is comparable to the Gladiator. Additionally, Hassan's/Carver's special in Dragon Quest Monster Battle Road is use of said Hela Hammer giving your monster team the recurring double-or-nothing ability as a buff.
...Er, anyway, Mac is like a DQ Gladiator. Savvy? ;
I believe these are from the Equestria Prevails Comic series that is currently in progress. Unfortunately, we havent seen Big Mac yet, so besides the overall look, I dont see any other cles pointing to it.
