The Fall of Slatreos

I've been waiting a long while to get to this! I took what I learned from OST Jam and used it for this.

Lore Time:
The End of Slatreos:
The day of sealing is a universally observed event as it was the day The Demon of Ruin, Slatreos, was sealed between dimensions. Every being in the known universe is required to learn the ritual of sealing once they come of age so that if any last second picks need to be made it will be. It is also required by intergalactic law to show if you have been chosen. If the chosen isn’t a gem wielder then they will be temporarily supplied with a gem.
The materials required for the ritual of sealing are the red gem, the yellow gem, the green gem, the blue gem, the purple gem, and a sphere known as The Stone of Kelum.
As the day of sealing approached, Gyro, Geo, and Techno were preparing when suddenly a ripple was felt throughout the universe. As it turns out, the ritual needed to start earlier than usual. Slatreos was breaking free. As they were the closest living beings to the interdimensional prison when the ripple happened, they were chosen to participate in the sealing since they already had gems they didn’t need to be supplied with temporary ones.
Upon arrival, they were greeted by a ring which was glowing with an otherworldly radiance. Shortly after their arrival, the red gem and its wielder Jerry, he literally wouldn’t detatch himself from the gem, were brought to the entrance of the interdimensional prison in a container so no one would touch it. After a few minutes a purple gem wielder named Alm was brought in and with him was Lex’Minot who bears The Stone of Kelum.
As everybody got into position something felt… off. Just then another ripple was felt and this time it was stronger. Something was wrong and the ritual needed to take place then and there. As is protocol everyone used their gem and stone at the same time at a sphere Gyro made as he shot everything he collected at the red gem in a continuous stream. Everyone’s gem began to glow white and an energy connected them when suddenly another ripple was felt. The red gem began to glow red and shot a beam of energy at the interdimensional prison’s entrance, causing it to be destroyed. The ritual failed.
As the prison's seal was opened everyone was sucked between dimensions, including the red gem, the missing piece of Slatreos’s power. A booming heart was audibly heard throughout this space and in the distance lie more entrances. Only one entrance however was distorting the space around it, the one they came from.
As they recollected themselves and looked around they all spotted Slatreos just standing there. Without warning the red gem launched itself inside the infinite hole in Slatreos’s head and with it went Jerry, the first fatality to Slatreos himself in over 3 millennia. Slatreos had his missing piece and the battle for the universe began once more.
After multiple near death experiences and a hard fought battle against the Demon of Ruin, Slatreos fell to his knees. He exclaimed with hatred and bloodlust in his voice, “You killed me now but I will one day return! I will never truly die! My influence on this universe is eternal! I am entropy! I am the end of all things! I AM RUIN INCARNATE!” With a final ear-piercing screech that struck fear into the minds of everyone there, he fell and died, the red gem falling out of his head glowing crimson red. From the infinitely deep hole in his head, a black sphere and a white sphere escaped into the universe.
No longer needing to worry about Slatreos, Alm, Gyro, Geo, Techno, and Lex’Minot went home terrified of what just transpired and of what could happen next. This is the beginning of their rise to glory.

Abilities:
Reality Tearing (can cut into space-time using his claws to create rifts)
Mind Control (through the use of the red gem)
Red Gem Creation (It's draining but he can do that)
Minor Creation abilities (can create small objects from nothing)
Energy Manipulation (His tentacles can shoot beams of energy and he can shoot a large laser from his face)
Time Dilation (can move at light speed from the outside but he just slows down time using reality distortion)
High Impact Resistance (he's bullet proof but not invulnerable.)
Splitting (he can split into 4 clones each with one tentacle)
His face acts as a portal allowing him to shoot projectiles from it or grab someone with tentacles he controls
