So Scarlet and Mercy are both little flame dudets, right? And if u tell me they're the same person, I will do the worlds epicist facepalm EVER!!!

Yes Scarlet and Mercy are both fire-controlling girls. No they are not the same person. But they both have red hair, control fire, and are best friends.

Probally not they seem to have diffrent personalites but they may be the characters of good friends

I'm not Scar and Scar isn't me... Don't worry! XD
