That would be a Red Mage, a common job class in the Final Fantasy series. They're known as a jack-of-all trades, so they are capable of using black and white magic as well as swords. However, they will most likely not be able to use these abilities as well as the other classes that specialize in each.
Red XIII
I am pretty sure he is a Final Fantasy character. He is red. You can also see him in Mario Hoops 3-on-3 for the DS.
Fire red is not a Final Fantasy game.
Red XIII's real name is Nanaki.
Red XIII (Nanaki). He is the powerful leader of an unknown race in the Final Fantasy VII series. He is featured in most games and makes cameo appearences in Advent Children.
Auron, the red-clothed, no-nonsense mentor, originates from Final Fantasy X. As a supporting character and team member in Kingdom Hearts 2, Auron is also a sword-wielding protagonist with origins from FFX.
A moogle is a Final Fantasy character that are some kind of white cat that has a red ball on its antenna, a red nose and has black wings. A moogle can be found in almost any of the Final Fantasy games and also in Kingdom Hearts. A moogle has a very high level and can be used for some games as a party member. A moogles' voice is always described as KUPOH and has a strange sound in the Kingdom hearts.
Red XIII from Final Fantasy VII. It's his ultimate Limit Break.
He's called Cait Sith. He is one of the playable characters in Final Fantasy 7, he normally rides a large bouncy white creature (the red 'dog' is another playable character, Red XIII, aka Nanaki). It turns out that he is artificial, and that a human (a member of the enemy Shinra corp) is at his controls. However even after that revelation, he is still an ally all the way through the game.
I believe you're are talking bout either JENOVA *Sephiroth's Mother* or Red XIII *13* the one from the Cosmo Canyon Town, which is an unlock able character! Hope this answers your questions.

He is a character from baseball, the red sox.
