Yup! You did it right! (I'mjustsohappypeoplearen'tignoringwhateverIsayforonce - since I'm an alt.)
Here's your OC!
Gender: well, whaddya know . . . it's a BOY! *celebration balloons pop*
Tribe/s: SeaWing/IceWing hybrid
Powers: Can withstand freezing temperatures, can swim in freezing water (cold enough that most SeaWings won't want to swim in it), has an stronger-than-usual IceWing tail, but the spikes are blunted a bit, can breathe frostbreath only when cold enough (in Ice Kingdom, mostly anywhere else is too warm). His scales do not light up.
Strengths: He is mentally resilient - insult him and you'll be the one dying of embarassment! Being a hybrid only makes him prouder. He plans to marry an IceWing princess so that one day he will be able to help both tribes better. He will fight and die for his tribes, although his fighting skills are not the best . . . he has loyalty. He can survive for a while without any food (don't ask why, because I don't know why XD). He is strategic and a careful planner. He is a very good swimmer; he won the swim competition of 5012 (same time as MR and JMA). Good talking skills.
Weaknessess: His little brother, who was born with no horns and only four claws on one talon. If anyone dares insult him, they will get a face full of not-so-sharp spikes. This could lead to a fight, and Marlin isn't the best fighter. He is very sensitive to heat. If he is exposed to extreme heat for a long time, he will first have a migraine, then faint. If he is exposed long enough (ex. living in the desert for the rest of his life), he could very possibly die. He needs water. To drink, to swim in, etc. Sometimes he is so careful planning, he never gets around to action. He is a bit shy when meeting hew and imposing authority figures.
Personality: He is shy at first, but love a good debate and speech. He will rally for the underdog no matter the case, knowing from personal experience how hard it is. Although he is good at planning, sometimes all the plans he makes confuse him (imagine having 15 different to-do lists!) and then he just gives up and restarts all the lists from scratch. He is often tired, and thus as a result can be quite grumpy in the mornings. He will do anything for his younger brother. He is not the romantic type (except for his planned IceWing princess), so don't bother crushing on him. He will have a smart retort at the ready, always . . . because he is that type of dragon. Marlin will do what he wants when he wants how he wants it, if only to save a single dragon! He is freakishly loyal to both tribes (although the SeaWings kind of kicked his family out) and his family. He respects older dragons/authority.
Appearance: Marlin is a hybrid, so his tail looks a bit odd. There are no stripes anywhere on him at all, but there are areas that are brighter than usual in a stripey-looking pattern that resembles a wave traveling around his body. His tail is thicker and stronger than the usual IceWing's, but not as strong as a SeaWing's, and the tail spikes at the end of it are a bit blunted, and the impact doesn't hurt as much, but they do exist. His claws are a weird lime-ice color, and his talons fade down to his arms a light pear green with white scales here and there. He has bright green eyes. His underbelly is a regular IceWing's color, but with hints of sea-blues within it that fade down to the underside of his tail and the inner edge of his wing membranes. His wings are entirely chilly frost blue, the kind in the sky on a snowy day, except for the edges that are icey-sea-blue-green where they meet his torso. His stare is quite penetrating.
Other: He is Winter's fourth cousin, so although he is not directly in line for the throne, he is royal. The only way for him to be king is for the entire royal IceWing family to die and for the remaining mhei to marry him, which is highly unlikley, but it is faintly possible.
I hope you like him! It was fun making him! Enjoy!
