Same history: Kog, Level Up, Kill3r Combo, Grand Chase (#LongLiveTheChase), I love these games, BLAH BLAH BLAH.
Well, Raven is a Nasod hybrid (Nasod are a race of robots in Elios, Elsword world), he have a sad history (some bad guys killed all his friends... AND HIS WIFE (I think), BUEHHH...... In his front... Yeah, I'm so sorry Raven...), and he is more old than Elsword and Aisha (the most old human character... There is too, an ancient Nasod Queen, and Rena). And well, the sprite is cool (more than Rena... Ok so sorry Rena too). Now, have fun.
(The Nasod-Arm got bad, but this was my best "e_e)
