• Ethnically appears to be Eurasian.
• Left eye is green, right is blue. Can be drawn with oval framed glasses.
• Hair can either be cut rather short or reach his shoulders, but never ties it back or buzzes it.
• Has teeth that are slightly too large for his mouth, especially his canines and lateral incisors (which are pointed). Rarely smiles with mouth open. His teeth can sometimes be seen when his lips are closed.
• Has tons of scars, mostly concentrated on his outer forearms and shoulders. None of them are consistent save for his inner left wrist (shaped like a grid).
• Missing part of his right pinky finger.
• His teal pilot suit and brown cloak are references to Ryoma of Getter Robo, but he's more likely to wear a regular Londo Bell flight suit.

On the outside, Joe is reclusive and shy, the only exception to that would be when he is in the company of those he feels comfortable with, or if a particular subject catches his attention (music and insects are his favorites). When not hiding behind his violin or guitar, Joe is dutiful, soft-spoken, emotional and extremely sensitive, outwardly exhibiting all the courage and grace of a kicked puppy. A large part of his personality is still dominated by past trauma that he's still processing, which unfortunately manifests in his introversion at best, and night terrors and flashbacks at worst.

Hiding underneath his somewhat vulnerable exterior and oversized coats is a strong willed, pragmatic and determined warrior who is willing to fight when he's needed. He's motivated to protect his family and people as a whole. He feels it's his responsibility to do whatever it takes to ensure his loved ones' safety - even at the cost of his own well being. 

Whether in flight or fight mode, Joe is able to acknowledge his own weaknesses and unfamiliarity with certain things, particularly his combat abilities or social situations, and often relies on hastily made plans instead of his strength when in a fight. Over all, he prefers to pursue diplomatic solutions before engaging in combat.
