Twisted Fate will be reverted to his past self from a little over 10 years ago. Which means he's still a pirate, does not even go by Twisted Fate yet, and is a little less of a jerk and more playful. For a keen eye, he is still recognizable, as his eyes still glow and he definitely still is using magic to bend playing cards to his will.

Hanzo Shimada will be reverted by about twenty years, down to 18 years old. He'll be a recent graduate of high school and just starting to truly face what his (supposed) destiny is in the family business (eyyy, organized crime). Also less of a jerk, but wary about how to present himself to others, so he'll come off as a flipflop of being exceedingly confident and exceedingly shy/wary.
