A heart full of gems.{My hero academia X OC}{Need to fix}

Prologue/Bio

Name: Tyler Barnes (So I originally said this was a friends OC, but in all actuality its my OC.)

New name:Tyler Todoroki

Age: 15

Quirk:Can harder skin/make jewels. (Emeralds, Ruby's, Diomond,etc.), can control fire(Purple color,and normal), Poisin, and Lightning, and Ice.
{Based off Ark Evolved Wyvern's. Except for the jewel part.}

Poison: Tyler has a very strong immune system so his body can handle his own Poison. Will never use it unless he is cornered or near death situation. (Last resort. Or against Nomu's.)

Fire(Purple.) It is hotter than Blue flames. His body can surprisingly take the heat, by producing sweat making his flames cooler for him, but hot when he uses it to attack.)

Fire(Normal): Nothing really special.

Lightning: He can control Lightning like Denki, but also use it to make him faster.

Ice: He can due what Shoto can due during the Sport Festival Arc, and due to his ice being extremely cold he can regulate his fire power.

Harden skin/Jewel: His skin can turn into any type of jewel. (Obsidian is technically a jewel, Diamonds, Emeralds, Rubys. Everything I said above.) He can also make them much like Momo, but they can stay out without using his quirk. So like gifts in a way.)

(He is also part Neko.)

Hero name: Ark Dracanevrn

Love Interest:

You get say, But due to the fact I like Jiro. Jiro is a 100% in this story.

Ember Todoroki: Older sister of Tyler, and half sister of Shoto.

Quirk: Has wings, and fire control. Black, and normal flame color.

Wings: Her wings are purely made of black flames, and yes. She can fly. She also has normal fire power. (Here wings are Phoenix wings.)

Hero name: Phoenix

Tyler Bio: Tyler was born from quirk breeding he was only child. His parents were well known villains, and thus tracked down. Once they were captured he fled. Running. He lived on the streets until Ember came, and adopted him into the Todoroki family. Tyler is 14, and do too getting so many recommendations, and being very smart, and hard working he skipped a grade so he is in class 1-A with his brother, and sister. He is also like Shoto not very social at first, but then talks more when he gets to know you. If he uses his quirk to much it'll take a day to recharge each element, and he can use all of them in one day,but cannot use all of them at once. If he hardens his whole body he cannot move. He figured all of this out while training with Shoto, and Ember.

Embers Bio: Step brother of Shoto. She was accepted into the family. Once she saw Tyler she felt bad, and took him in. Now they care about each other, and Tyler is welcomed into the family. He even accepted there last name to prove that he was happy to be a Todoroki. Shoto, and Tyler get along very well, and train often. She watches sometimes, sometimes she even joins them.
