Top 15 Sonic pairs.

I have five new ones to my top 10 and shuffled some pairings around.

15. Ash the Mongoose and Shade the Echidna: It's a crack pairing, but what the heck? I kinda like it.
14. Ray the Flying Squirrel and Marine the Raccoon: Puppy love. You know, that kind of love that it's like 'Aww, how cute', when you see them as kids, then when they are older, you see them as 'aww, they are going to be together.' Plus, their personas bounce really well off each other.
13. Jet the Hawk and Wave the Swallow: This is quite common in the fanbase and I can see why. They do work well together and they are on the same team too.
12. Mighty the Armadillo and Honey the Cat: Many fans put them together and I can see why. The fanart is cute.  
11. Espio the Chameleon and Mina Mongoose: Yeah, loads and back and forwards with him, but, this is quite adorable. I can see Espio getting Mina to come out of her shell a little and Mina to get Espio to kick back and have a bit of fun.
10. Charmy Bee and Cosmo the Seedrian: This makes more sense then Tails and Cosmo to me. Plants and bees go well together and I see their pesonsas bouncing off each other nicely.
9. Vector the Crocodile and Vanilla the Rabbit: I see them making each other very happy, and Vector being a good father to Cream.
8. Rotor the Walrus and Nicole the Holo Lynx. Again, fanwork got me into this pair. It's quite adorable, and I hear they have good moments in the comics.
7. Manic the Hedgehog and Amy Rose. I can see Amy looking past Manic's time as a thief and get to know him as the hedgehog he is. Plus, I feel Manic would be a positive influence on Amy and get her to let go of Sonic.
6. Knuckles the Echidna and Sonia the Hedgehog. They do have cute moments in Sonic Underground, and I feel they will bring out the best in one another.
5. Antoine D'Collett Bunnie Rabbot D'Collett. They have a perfect relationship, they have known each other as kids, been through everything together, and have adorable moments in the comics. Plus, their kids are amazing.
4. Miles 'Tails' Prower and Cream the Rabbit. These two have known each other for a while and I don't know why media hasn't attempted to pair them. Tails has had Cosmo, Zooey, Fiona and Mina at different points in the TV shows and comics, but not Cream. I feel they would be wonderful as a couple. Kid love first, then delving into dating later.
3. Silver the Hedgehog and Princess Blaze the Cat. After seeing Sonic 06 and games afterwards, these two are impossible for me to see with someone else. It's way too cute.
2. Shadow the Hedgehog and Rouge the Bat. This one ranks very high because, well, you almost always see these two together in a Sonic Game. There's been countless ship teases and some of the most heartfelt moments with them.
1. Sonic the Hedgehog and Princess Sally Alisha Acorn. Of course, I have to pair these two because of what happened in the comics and SatAm. In my mind, the reboot didn't happen and Sally, Bunnie and Antoine did recover and rejoin the Freedom Fighters. They've known each other since they were kids, they have great chemistry, they bring out the best in each other, they're children are adorable in the future, this will forever be my No. 1.

Honorable mentions: 

Scrounge and Fiona: Evil love at it's best I feel.
Bean and Saffron: I find it kinda cute. I also think Saffron can tame Bean somewhat.
Monkey Khan and Julie Su: It fits to me.
Elias and Megan: It's canon. Can't argue that. Also, I love how they got together and their daughter. 
Hershey and Gefforey: Again, Canon
Lupe and Lupo: Canon as well, and love their daughter.
Griff and Sticks: It kinda works too.
Ari and Dulcy: Why not?
Rosy Acorn and Uncle Chuck: It's quite cute. 
Aleena and Jules: I find Aleena more intresting then Beirne.
Maxamillon and Alisha: Canon again.
