So as an avid fanfic reader I sometimes forget a characters description so I'm releasing this as a quick reference of the dragon forms of both Izuku and Arashi as well as a run down of what the forms excel at. there will also be a costume reference but that will be released when those are revealed
Izuku' Dragon
Izuku's form is a classic western dragon body type (1 head 4 legs 2 wings 1 tail)
His scales match his hair and his eyes are a vivid bright emerald color with darker emerald tones on them
His two primary horns are a foot long with a slight upward curve
His nose horn six inches and curved up in an effective headbutt fashion
He's got 3 pairs of auxiliary horns on the back of his jaw at 2 3 and 4 inches from bottom to top
Izuku has a line of triangular spikes down his spine and tail ending just before his tail tip
All his horns/spikes/talons as well as his belly scales are pitch black while his wing membrane is a very dark green that almost looks black unless light shines on it
Izuku stands at 20 ft tall(15 at the shoulder) and 25ft nose to tail-tip
His dragon form while a capable flyer is better suited for teretrial combat, and excels in melee combat with thick hide a club like tail razor sharp talons and strong neck and skull for headbutts.
Izuku's form is not as fast or agile as Arashi's
Arashi's Dragon
Arashi has a wyvern body type (1 head 2 wings 2 legs 2 tails[not standard])
His scales are a black like a new moon night and his eyes are a stormy grey
He only has 2 horns which are a gun metal grey matching his talons and tail blades
While he doesn't have spikes the ridge of his spine is slightly raised and is a shade or two lighter than the rest of his scales
The scales on his belly and the membrane of his wings are a midnight blue and the wing membrane has flecks of silver
Standing at 17ft tall(10 at shoulder 10.5 at hip) and 28.5ft long(28 with out tail blade) Arashi excels in aerial combat. Arashi's form is fast agile and flexible allowing for great aerial maneuvering and hit and run tactics. His lithe form makes climbing easy but isn't as durable as Izuku, relying on his fire and his blades whip like tails
Yuki's dragon form (currently as a six your old)
Yuki has the body of an Amphithere (beaked head(picture buckbeak) snake like body 2 sets of wings and no legs)
Her body is covered in snow white feathers with powder blue ones mixed in
The inside/underside of her wings are MC diamond blue and the outer matches her body her stabilizing tail feathers match her inner wings
She's got two 2in horns on the back of her head about an inch and a half in diameter
Her eyes look like polished amethyst
From nose to tail tip she is 4ft with a front wingspan of 2.5ft and a resr wingspan of 2ft
