This is just to showcase extra abilities I may add to our arsenal. Some of these abilities were thought of by SONOW0409, so give him credit for them. I will also be giving out the Bios for our alternate Y/n and the three other Marinette's. Now let's get to it.

Divine powers
Energy projection
Energy absorption
Energy manipulation
Ability to fly at speeds 2/4ths the speed of Whis(still faster than anyone in your world)

Mastered Ultra Ego

[Abilities in use with the Cat Miraculous]

Main Power: Cataclysm.

The user infuses their hand, specifically the hand with the Cat Miraculous on it, with dark and destructive energy. Whatever they touch with that hand will be severely negatively affected. The user doesn't necessarily need to use their whole hand when touching the target.

[When used on a living being]
Living creatures and humans will be charred and turn into ashes too. However, if a person is wearing an active Miraculous, which makes them nearly invulnerable, the power will just break a few of their bones and/or cause decay in the cells, leaving a large dark necrotic scar over the part of their body that got hit.

The scar will gradually darken as the necrosis slowly progresses and spreads over the victim's body from top to bottom, causing occasional irritation, and the pain will get worse over time. Eventually, it will hurt the victim's internal organs and severely weaken them, until finally, the injury will ultimately causes the victim to crumble away.

They may also cough up ashes once they're near the end. Aside from the Miraculous Ladybug and the wish, no magic, medical care, or remedies can heal the injury.

Cataclyst Swipes:

Cataclyst Punch:

*The color of these punches and claw attacks will be black with a dark green begin his to it. If they are fully black colored..anything and anyone that get hit will slowly disintegrate into nothing but ashes*

Drawbacks for both: The power is limited enough to not cause too much damage, but still give intense pain.

Double Cataclysm: A more powerful, intense, robust Cataclysm, on both hands that could cause a much bigger extent damage. (Similar to what Plagg's Cataclysm can do, like destroying the whole Eiffel tower at once with one tap.)

Drawbacks: This can only be used on very rare occaisions, since it would be a lot of energy created at once and it could even be dangerous for the holder if they're not strong enough to handle it. 

Cataclyst Spear:

A technique where the user channels raw Cataclysm energy into a spear-shaped energy construct and then fires it as an energy bolt. Its power-level can be adjusted by the user, making it weak enough to just stun a target or powerful enough to inflict injuries.

Drawbacks: The Time of your Transformation will be siphoned by half. More of more energy was put into the attacks.

Cataclyst Blast:

An explosion of highly powerful Cataclysm energy that damages all that is within 10-20 yards.  can use it after charging the energy inside his body and firing it outside, which greatly damages, or even destroys, the enemy.

Drawbacks: With that Cataclyst Blast exhausing nearly 95% of your power, I can say that like the mega Venom Blast of Miles Morales..we would be very exhausted. The time on the miraculous would be short as you'll only have 10 seconds exact to hide before you are forcefully changed back to normal.

Cataclyst Flash:

An enormous blast of Cataclysm energy fired from the palms of your hands. One of the most strongest attacks in your arsenal.

Drawbacks: Same for the Chaos Blast.

And the final attack that you can do with or without the Miraculous active..

Here it comes...

Are you ready?

Hakai:

Yes..you are the son of Lord Beerus himself. Therefore, this makes you a demigod.

By channeling the Power of Destruction, a user can destroy almost anything with little effort, even working on intangible beings such as souls. The end result is the target being engulfed by a destructive energy wave, or simply disintegrating into an agonizing nothingness, becoming nothing but dust.

Non-corporeal beings, however, do not seem to experience the same atrocious pain as physical beings. The destroyed target then ceases to exist, unable to pass into the Other World.

This energy is so destructive, not even the healing magic of the Miraculous Ladybugs can restore the object or a person that was erased from existence.

These will be the two Forms you will get from training with your father and the angel attendant Whis.
