Please compare this pic to the original pic of Fai. [link]

I referenced Fai's outfit from this pic
[link] which belongs to who was kind enough to let me use his costume design. This pic was originally going to be Fai by himself but at the last moment, I decided to add Blaze. Keep in mind that this isn't a couples drawing, I added her because Fai and Blaze have numerous things in common.

They both have fire-based names and powers, though Fai is short for "Faia" which is how the Japanese say "Fire" in English, they both use Emeralds that aren't the Chaos Emeralds and are the guardians of them, Fai uses Nova Emeralds while Blaze uses the Sol Emeralds, the red dot on Blaze's forehead is somewhat similar to Fai's crest on his forehead which also has a red dot in the center but Fai's red dot resembles an eyeball because of the black "pupil" in the center of it which is also the Master Nova Emerald in a dormant state they and even have the same tornado moves as well as a few other similar moves but Fai can use Sonic's spinning moves including the Homing Attack. And finally, Fai is a prince and Blaze is a princess.

I kind of made Blaze noticably taller than Fai though Fai is the same height as (or probably taller than) Blaze is since he's 17 and she's 14.
