I'm surprised to see that some people actually like this character, because while she has a cute design and cares about Sonic, she's not entirely a likable character. This is mainly because she's a very spoiled and overly-sensitive crybaby who always expects to get her way and throws a fit when something doesn't go her way. She also cried uncontrollably when she got accused of secretly being Metal Robotnik/Black Eggman by Knuckles the Echidna. She's also self-centered, as she openly said she doesn't care what happens to Robotnik/Eggman or her dad as a way to convince Sonic to help Robotnik. To put it simply, she's a more immature and jerkish version of Princess Elise from the Sonic 2006 game. If someone decided to rewrite the OVA, I think Sara would work better as a villain. That's my opinion, anyway.

SEGA did mention giving Sonic a human love interest in the first game but they scrapped it, and instead implemented that into Sonic '06. I watched the OVA. Loved it
