Suggestions for oc?

So I have a few quirks in mind but don’t know which fit well for mha any help or suggestions would be helpful as he would be in class 1a or 1b
Quirk: Reptile
User: Kai Sato (Hero Name: Zilla)
Type: Transformation
Kai can completely transform into a massive reptilian kaiju-like creature. Unlike many transformation quirks, there are no partial stages—he is either fully human or fully transformed.
Abilities
Massive increase in strength
Incredible durability
Enhanced speed and reflexes despite his size
Powerful jaws and claws capable of cutting concrete and metal
Heavy tail used for sweeping attacks, balance, and devastating strikes
Retractable dorsal spikes for offense and defense
Thermal vision
Enhanced smell and night vision
Detects vibrations through the ground and water
Exceptional swimmer
Can fight underwater with little loss of mobility
Natural armor made from thick scales
High resistance to blunt force, heat, and cold
Limited regeneration (cuts and broken bones heal faster, but lost limbs cannot regenerate)
Can hold his breath for 45 minutes to an hour depending on activity
Strengths
One of the strongest close-range transformation quirks.
Excellent for frontline combat, rescue work, and disaster response.
Functions almost like a living tank.
Keeps full intelligence and personality while transformed.
Weaknesses
Extremely heavy and can accidentally damage buildings and roads.
Difficult to fight indoors or in tight spaces.
Burns enormous amounts of calories.
Extreme cold slows him down slightly.
Size makes stealth nearly impossible.

Quirk: Beast Form
User: Kai Tanaka-Bakugo (Hero Name: Wild Shift)
Type: Transformation
Kai can transform into any modern-day animal that currently exists on Earth. Every transformation is complete—he cannot create hybrids or partially transform.
After awakening his quirk, he gained access to extinct prehistoric animals as well.
Base Ability
Transform into:
Mammals
Birds
Reptiles
Amphibians
Fish
Insects
Marine animals
One animal at a time.
Awakened Ability
Can transform into extinct species, including:
Tyrannosaurus Rex
Spinosaurus
Velociraptor
Smilodon
Ankylosaurus
Megaloceros
And potentially any extinct animal he has mastered
Strengths
One of the most versatile transformation quirks imaginable.
Perfect for:
Reconnaissance
Search and rescue
Espionage
Tracking
Close combat
Mobility
Every animal grants its natural abilities.
Retains human intelligence while transformed.
Weaknesses
No hybrid forms.
No partial transformations.
Cannot speak while transformed.
Only one form at a time.
Large prehistoric forms place significant strain on the body.
Excessive use risks “Mental Drift,” where animal instincts become harder to suppress until reverting.

Quirk: Siege Roll
User: Kenji Kurosawa (Hero Name: Crashbone)
Type: Transformation / Mutation
Kenji reinforces his skeletal structure, causing his bones to thicken, harden, and interlock into heavy armor lined with bone spikes.
He can then compress his body into a high-speed rolling form that functions like a living wrecking ball.
Abilities
Reinforced skeletal armor
Bone spikes increase damage on impact
Compresses into an armored sphere
High-speed rolling attacks
Incredible momentum
Excellent durability
Can crash through walls, vehicles, and heavy obstacles
Bone armor also enhances hand-to-hand combat outside rolling form
Strengths
Devastating close-range offensive power.
Momentum continually increases impact force.
Extremely difficult to stop once fully rolling.
Naturally durable even outside his signature attack.
Weaknesses
Hard to change direction at maximum speed.
Vulnerable during transformation in and out of rolling mode.
Generates intense friction, risking overheating.
Heavy calcium consumption causes bone fatigue with excessive use.
Internal strain limits prolonged combat.
