The GaMetal Bard (or Mage as we previously called him) is the official mascot of GaMetal, and he’s actually just a recolor of the Red Mage sprite from Final Fantasy I (not a Terraria character!).
It’s also a bit symbolic to me: in Final Fantasy I, the Red Mage was able to use both Black and White magic, and was able to use most types of equipment, with the main drawback being that he couldn’t use the top tier stuff. He was a jack-of-all-trades. Much in the same way, I play the guitar/bass/drums/keys in my songs… but, like the Red Mage, I’m not exactly the best at all of them!
