Nicole the Holo-lynx. I think she's my favourite too. From her character development, to her design. I LOVE her post-reboot design. (not that I dislike Yardley's design, which was great too). I am fascinated with the science-fiction trope of "machine that becomes alive" and those sort of topics, and Nicole basically IS that trope... BUT, there's a close second (if not at the same level), which is none other than Bunnie Rabbot. Why? C'mon, look at her, sugah... Aside from her somehow super-hero-esque design (someone said Cyborg?) which I see as a challenging vision of Sonic the Hedghog's original conflict (Nature vs. Machinery) I love the way she is: energetic, sometimes savage, sometimes sweet, like an older sister to the younger members of the team, like a mature fighter with the most veteran ones. In my humble opinion, her romance with Antoine is easily the best love story in the entire franchise. And that Southern American accent... I love it. Ah ain't gonna lie, it makes me laugh.
My all time favorite is probably Nicole, (Though Antoine is a close second) partly because she has had the most development over the series. At first she's a sorta cool computer and then BOOM! Single handedly saving the freedom fighters and every one else from Eggman. That and building a personality from nothing (at least in the preboot universe) while still maintaining a part of her that is still distinctly computer. She's such unique character and just a fresh breath of air in the series, showing there's more to fighting eggman than busting badniks.
Without taking regard to Sonic game characaters (Sonic, Tails, Knuckles, Amy, etc.), which of the members of freedom fighter is your favorite and/or most interesting? Aside from picking a vote, please also state why you like the character and what are most interesting aspect of the character (personality, development, etc.)
