Izuku Midoriya: King of The Kaiju (Izuku X Harem)

Explaining his Powers:

Izuku will be OP as shit in this story, and that's to be expected given that he'll have the power of Godzilla and his intergalactic counterpart. Below will be listed on what Izuku will do and what he's capable of.

GodZilla:

1: Monstrous Strength: Able to surpass normal strength quirks, but only about equal to All Might's strength.

2. Roar: With his powerful lungs, he can give out the infamous roar in variant situations. From loud enough to shake an entire stadium, to the entire globe!

3. Magnetic Pull: Emitting electricity in his body, he can attract certain metals to his body.

4. Nearly Indestructible: His natural skin is tougher than steel, only able to be scratched when a certain area has been hit too often.

5. Laser Blast: Shooting from his mouth is his signature move where a blast of pure radiation goes out. Only used in cases that call for that much power.

6. Razor Claw: Extending his naturally long fingers, he can shred right through almost any metal. Tougher ones require more strength and can hurt him.

7. Height Increase: Similar to gigantism quirks, when he really cuts loose, he can grow to 300 meters tall, his appearance taken on the infamous King.

8. Swim: In water, he's faster than a torpedo, close to 200 miles an hour in an instant.

9. Increased Senses: Hearing and smell are 10x greater than those with quirks that have that perk.

Again, he'll be OP. As. SHIT! And that's just Godzilla, that's nothing compared to SpaceGodzilla.

SpaceGodzilla:

1. Aura: Emits an aura that causes electrical disturbances.

2. Corona Beam: He can fire a Corona Beam from his mouth that he can control as it moves through the air.

3. Crystal Formations: Izuku increases in power by being near gigantic crystals that he creates. He's also able to unleash bolts of energy from the crystals on his shoulders.

4. Energy Conduction: He can conduct energy through touch. He's also able to implant cosmic power in structures that can transmit a signal and have them act as an energy source.

5. Flight: He can fly by means of encasing himself in crystals. On Earth, he is also shown being able to levitate himself and fly around in an upright posture.

6. Prehensile Tail: Izuku's tail is somewhat prehensile, and can lift heavy objects after stabbing them with the crystals on its tip.

7. Regenerative Abilities: He has super regenerative powers, though it takes longer depending on the injury.

8. Shield: His Crystal Shield is nearly unbreakable, made entirely of his own crystals. He can even encase his body in a shield to deflect projectiles.

9. Telekinesis: He also has telekinesis which he can use to move and levitate objects. One of the only powers that's similar to his parents.

Though he's gonna be super strong and tougher than a tank, there are drawbacks.

Weaknesses:

1. Very Slow: Not made for speed, he's very slightly faster than a regular human, but will loose against someone with a speed based quirk.

2. Weak to Man Made Electricity: If shocked by a quirk or generated electricity, it will cause major harm to him.

3. Slightly Clumsy: His bulky form and tail make it somewhat hard to move around and can distract him.

4. There is a limit to how much punishment he can take, he is tougher than most, though he can still be harmed.

5. (Will be said in first chapter.)

So yeah, that's what he's got going for him power wise, and I know there may be speculation around it. For starters, you may wonder if he'll get OFA, and I'll say, not off the bat, All Might still need it. Anyway, the next chapter will mention who will be his harem, which will be a LONG one.
