Not making it in a full-fledged countdown because...
1) This list has some predictable choices and there is already a lot said about them so I'll be brief.
2) I'll be really repetitive otherwise
3) I think I wouldn't be able to do them full justice anyway. I'm not up to levels of Joshscorcher or the Autarch of Flame in terms of countdowns after all.
So...I just like Sonic the hedgehog as a franchise, and so I give my top twelve characters. It was hard enough picking them as it is, even if I was making it a top twenty-five.
Why twelve? It's a lucky number in greek myth, since twelve represents perfection and refers to the pantheon of olympus. Adding one to it becomes the unlucky number thirteen. You expected that for an answer? Oh well; not beating around the bush, just the twelve I like most, here and now.
12 BEAN THE DYNAMITE
A character pulled from obscurity and into a full fledged character in the comics with a very entertaining personality. He just cracks me up.
11 RELIC THE PIKA
At first I didn't like her...but over time she grew on me. She is kind of adorkable. She isn't just a filler for Julie-Su, she has a few fun quirks of her own. And her intelligence will prove useful in the future for Knuckles.
(PS, am I the only one imaging Tabitha St. Germain as her voice actor?)
10 BUNNIE RABBOT
I like kickass girls. And it happens one of the main characters of the comics is such a girl. What better then a cyborg southern belle cowgirl rabbit who is the mother as well as the brawler of the team?
9 ROTOR WALRUS
Poor guy doesn't get enough love. He was both the brain and brawn before Tails was established as a prodigy, so I was sad he was shoved aside in the comics for a while. I'm at least glad he got over his injury and back in the field again. I kind of miss the blubber on him, it's healthy for a walrus to have it. But seriously people, give him some love. He earned his spot on the team.
Do I really need to say? He was Sonic's greatest foe since day one and without him, in any incarnation, there is just no Sonic franchise. Whether you like him over the top and silly like the games, where he is so much fun to watch, or the ruthless dictator that turns people into literal machines for conquest like Satam or the comics...the mad doctor, as fun or as awesomely dastardly as he got will forever be a staple of the franchise. He is doing his best to give us his worst and we like him for it.
7 MEPHILES THE DARK
Even if 2006's story was convoluted, it did something right. Mephiles is one of them. Basically bringing the devil into a Sonic game. A lying, manipulative dark entity shapeshifter with a creepy laugh, awesome deep voice and the only villain from the games who succeeded in his goals: killing sonic and become Solaris. He was my favorite villain for a while and still ranks up pretty high.
6 METALLIX (aka Metal Sonic)
Eggman's greatest invention was a robot duplicate of Sonic who soon surpassed his counterpart and his programming; Whether becoming something close to a god with the data of twelve heroes and residual Chaos energy, or just being a powerful obstacle to overcome, he is probably the best evil copy in gaming history. There are also many cool version of him: Metal Sonic, Mecha Sonic, Metal Overlord...heck, Captain Metal and Shard are in thier own ways cool incarnations of Metal Sonic. Even in Sonic Boom he couldn't be just left out...because you just don't. You don't leave out the king of mechanical maniacalness.
5 DR. FINITEVUS
This guy...this f***ing guy. He just screams badass. Nihilistic...creepy albino look (that make him really standout from all the generic echidnas), cool warp ring powers, able to shrug off blows from Knuckles himself and that cape! Who doesn't want a cape like that?...and it doesn't help he's bat shit insane. And insane characters are always the coolest villains. I'm mad at the reboot, now he's gone...But seriously, look at this guy and say he is not frightening. It is about time Knuckels got some rogues of his own and he got a good one.
4 SONIC THE HEDGEHOG
Sonic himself has to be on the list. Surprising he's not number one. The only reason is I like the other three more. But Sonic himself is cool as a character, he has to be to keep his franchise alive and successful all this time; He is heroic, cocky, has the attitude and is a snarky bastard. It's especially the snark. I love some snarkiness. What else do I need to say about him? He's sonic the f*** hedgehog, the fastest thing alive and just a cool character. I'm so glad that this mundo cool spikey guy started it all.
3 MILES ‘TAILS’ PROWER
I like Tails more then Sonic. He has all his powers plus some. He can spin-dash and be fast enough to catch up to the blue blur. He is also smart enough to build machinery from the simplest materials plus a fake Chaos Emerald, and he also has chaos powers like Sonic. And he's only a kid...who is arguably as smart, if not smarter then Robotnik himself. Combining brains, power, wisdom beyond his years but still a likable amount of child-like spirit, Tails is my favorite game character in the franchise.
2 SALLY ACORN
Sally Acorn was the first character ever that I remember seeing giving a middle finger to the princess in distress cliche. She was no Princess Peach. She didn't just take the fall of her kingdom lying down and leads an actual resistance against the invaders. Using her skills in tactics, diplomacy, stealth and martials arts to the table she was a strong female lead, which aren't enough from in any franchise since most franchises turn into sausage fests. Oh, and I'm a Sonally fan, sue me!
1 NICOLE THE HOLO-LYNX
Nicole is not only my favorite Sonic character but also my second favorite fictional character ever, only second to Raven from Teen Titans. For a little computer she is oddly enough the most...human or Mobian of the sonic cast. Her intelligence, desire to understand emotions and eventually becoming just as Mobian as her comrades as well as having a bit of snark at times (even if only in the cartoons) there was a lot to like about her.
When I learned her intended backstory for Satam of being a childhood friend of Sally whose mind was infused in a computer, that bit of sadness sealed the deal for me and added to this already great character. I'm so glad they are bringing it in the comics now as well. So yeah, Nicole is just awesome. Cute, great personality, a character to relate to and having great backstory she is such a complete package she takes this spot by storm.
