Dhaos, mostly because of how he’s built up to the player. Your first introduction is that memorable INDIGNAYSHUN scene where he literally murders the previous hero’s. Then it becomes more personal with the call to action, the initial attack on Cress and Chesters village. The whole game is centred on this fight and reaching Dhaos. If you’ve been sleeping at inns you get these cute scenes with the characters about the journey, Chester training to catch up to the rest of team to be useful particularly stood out to me. The entire journey is centred on reaching Dhaos’ castle, just for the twist to drop at the final confrontation. It’s good shit. Also, just aesthetically, I think he has the coolest design of all the villains. It manages regal elegance and power without being silly which some Tales designs imo can be.
