Flint stands at the height of 5'5. Has jet black hair thats a tad spiky. He weighs around 125 lbs and his eyes are teal in color. He often wears a short sleeved hoodie over a plain colored shirt with baggy jeans. His hood is always on his head hiding half of his face. He has a sling backpack over his shoulders often containing nothing at all. He is always seen with a mechanical pencil in his hands even if he doesn't have his sketchpad out.

Even though he has a hoodie over his head that hides half of his face, he often wears a grin and is most of the time happy-go-lucky. He's honest although he keeps his opinions to himself. He has a transparent face meaning almost anyone can read his emotions fairly easily. He spends his spare time in the park either seated on a tree branch over-looking a lake, or simply spinning the pencil in his hand.

Flint lives alone in an apartment while his parents continue to support him through his education. Both of his parents are doctors and are both currently in different countries and rarely see each other. At the age of four he begun his training in Taekwondo and a little Karate. At school he is just a regular guy causing trouble every now and again. Often getting in trouble due to doodling in class, his grades are average, aside from math. He hates anything having to do with calculation.
