Magical Renegades sorta 10th anniversary part 4

Melody and Tricia are two of the characters I created for a prototype story to Magical Renegades, and they've had some of the most drastic re-designs. When you redesign a character so drastically, and rewrite their backstories, would you consider the current versions be considered the same characters as before, even if in name only?

It's obvious I originally designed these characters back when I was in middle school, especially Tricia. She was the character who swore a lot, and picked fights with friends and foes alike.

She was originally one of the toughest characters, but since she's still only human and many of the other characters who were human in their original designs now aren't, she still has some tricks of her own and is a skilled survivalist.
