MC's daddy will definitely be a powerhouse, but unfortunately Oda doesn't give a shit about him & Mihawk.
They're going to be both strong. No doubt, but yeah.
Mihawk will job to Zoro, and Dragon will job to the FV (maybe Imu) Wyper style. Did that prediction 12 years ago, and nothing changed in my opinion.The only saving grace for Dragon is unless Oda is going to pull another death (unlikely), he will be unlikely to get hard power creept like the yonkeks as his fight is going to be in the final arc.
Not guaranteed with Mihawk. I've seen even some hardcore Temple Bros admit there is a chance that the battle against will place before the final arc, but I'm not sure myself currently
