So the vote's for his power/magic is both toriel's fire magic and sans and papyrus skeleton's magic

here's what his magic is.

*pretend that frisk is izuku *

Fire magic - izuku is able to control and summon fire at will, and is able to call waves of fire, expanding rings of fireballs, rains of fireballs, and spiraling pillars of flames, and izuku able to turn the fire into weapons(from the Endertale A.U When Chara takes over Frisk body with the HATE Trait and is able to make the fire into a knife.)

Blue magic - Izuku is able to uses a magical psychokinesis but for his eyes idk what color should it be

Choose for eye color

- Classic sans light blue and yellow

                     or

- Red

Bones and Blue bones - Izuku is able to summon bones from the ground and at will and his uncle sans and papyrus taught him a new bone attack called blue bones, blue bones allow izuku to stun his enemies and if they tried to move they feel pain.

teleport/shortcuts - Izuku is able to use his eye to teleport or travel and called his teleport his "shortcuts" just like his uncle sans

increase bone attack - just like his uncle papyrus izuku is able to make his bone attack smaller or bigger, here's a look of the size of the attack increase.

Gaster blaster's - Izuku is able to summon dragon like blaster's that fire laser attacks that are hot enough to burn.

I forgot to mention this in the bio but he's gonna have the same power as gt frisk in the glitchtale universe.

Human soul magic

Concentration determination - izuku use able to use his soul trait on a knife that his sibling chara gave to him and he can concentration putting his determination on the knife.

DT slashes - Izuku is able to crate Determination slashes when he concentration his DT on the knife.

Here's what it looks like:

Also quick question should i give Izuku the Determination sword and shield not only the knife?.

Also DT is short for Determination

DT Blade wave: Izuku is able to stab is sword in the ground in an angle causing a slash from the ground come out and anything it hit causes an explosion.

Here's what it look's like:

Determination explosion: If izuku stab his knife that's filled with determination into the ground it will cause an explosion.

here's what it looks like:

Determination guard : Izuku is able to create a giant DT shield with his trait.

A/N: 'I forgot to add this one'

Spherical Shield: This shield functions like the green used. It can surround a target with a sphere causing the target to be trapped inside of it. The target can still crack the sphere, but it's unknown if the target can fully escape it.

 Armor of The Red: This is an invisible barrier that surrounds the user's body to possibly reduce damage.

that's all his power/magic moves.
