Reddish noodle~
this just came out of my mind
Red noodle or Red sons hair represent his fire element so
here are some of my ideas that I think it's interesting
a tip:
(so we all know when he is angry his hair lite on fire and like others when he gets shocked his hair gets spiky, his hair shows his feelings more than others)
an extra tip:
(sadness is the longest-lasting emotion, jealousy, contentment, disappointment, disappointment, anxiety, hope, desperation, joy, hatred are long-lasting emotions)
(shame, surprise, fear, disgust, boredom, being touched, humiliation, anger, irritation, and relief are the shortest-lasting emotions)
what if he gets super excited his hair dances like a really nice burnt fire whit rhythm, hehe his ponytail waving like a puppy's tail.
and let's consider when Demonbullking was bad talking to Redson because Redson knew his father was not in his right mind, he got really sad but it didn't break him...
so let's say if something similar happens in the future when Demonbullking meant what he was saying this time and broke his son's heart. his hair ponytail and bangs will slowly fall down and relax because...his dad killed his spark in his heart, his core, the source of his fire, comes from passion and joy, tenderness, fondness, and feeling .that causes him to not be able to fire bend again until he gets his spark back.
think about a broken red son who is running away holding his tears and is now hiding to cry and after a while, he finds himself in trouble while other demons are surrounding him while he just found out he got powerless....ouch
anger is a fast and short live expression, so it just burst into it and gets a huge short range of fire explosion, I am thinking about long term expressions, maybe like joy, enthusiasm, and relief, positive long-term emotions, probably he will know when he is falling in love or having a crush, his hair starts dancing and his breath is so steamy that brings fire, he will try his best not to make it obvious and will say "oh that is definitely under my full control and is the new skill I'm working on it so, yeah sometimes it's hard to control it I'm new to it" (you lier, you can't control your body)
