With the encounter with Paradox, Rex understood his current situation.
He has been here to help Prime Ben and his friends to stop Aggregor.
Before that he needs explain his partners living inside of him.
Rex: Albion and Lykaon, I will explain the situation that we are going face. Previously I had told you both that I was reincarnated as an alternate version of a powerful character. This person also wields the Omnitrix and first user and the prime one from which other alternate realities were created including mine also.
Albion: [So you are summoned here to help the Prime Ben Tennyson. Now who is this Aggregor?]
Rex: Aggregor is an Osmosian just like me and an enemy of Ben Tennyson.
Lycaon:{He is an Osmosian just like you. So what is his goal?}
Rex: His goal to become omnipotent and conquer the universe.
Albion/Lykaon:[{How will he achieve it?}]
Rex: By absorbing the powers of a baby Celestialsapien and use it.
Both the Vanishing Dragon and the Werewolf king were shocked.
Rex has told about the aliens that the Omnitrix contains. One of them is Celestialsapien.
Celestialsapiens are a race of immensely powerful reality warping beings native to the Forge of Creation.
Celestialsapiens are the most powerful species in the universe, being capable of controlling reality, space and time. Their reality warping is seemingly without limit - a Celestialsapien can make their very thoughts become reality and survive anything up to and including the destruction of the entire universe around them.
Rex: Also Aggregor needs to absorb a baby one rather than an adult because Celestialsapiens develop multiple personalities over time. In the case of adult, it will be a problem for him. But a baby Celestialsapien does not have multiple personalities and it is also not mature enough to use its power. Now let explain me how Aggregor started this?
Rex began his explanation starting from mainly Aggregor.
Aggregor belongs from a species called Osmosian where Kevin and Rex also belong.
Unlike Rex and Kevin, Aggregor is an artificial Osmosian created by Dr. Servantis, the leader of Rooters using Kevin's DNA. But later his memories were erased by Rooters and later set him loose in the Null void after Ben removed his Omnitrix.
Studying the legends of the universe, Aggregor learned about the Forge of Creation and schemed to collect the pieces of the Map of Infinity to gain entry and absorb the powers of an infant Celestialsapien. That way, he would gain unlimited power and omnipotence and rule the universe.
But in order to survive the dangerous journey of assembling the Map of Infinity, Aggregor captured five powerful aliens from the Andromeda Galaxy so that he could absorb all their powers and abilities into his own being using a machine he had built back on Osmos V.
He needed a machine to completely absorb all the powers of the 5 Andromeda aliens that he captured. Due to certain circumstances, he had used the Chronologger from Professor Paradox's old Time travelling experiment as the replacement for the machine on Osmos V.
No matter, how strong Aggregor is, he is still a normal Osmosian which means he can absorb 1/10th power of the chosen alien. To fix this issue, he created this machine. Later he completely absorbed all five chosen aliens without leaving any essence of them. It transformed him into a massive chimeric mutant known as the Ultimate Aggregor.
All the 5 aliens that Aggregor absorbed belongs from Andromeda galaxy.
Each of these aliens are unusual with their respective elements.
(1) Galapagos from the race of alien species Geochelone Aerio. Main ability is Aerokinesis.
(2) Bivalvan from the race of alien species Orishan. Main ability is Hydrokinesis.
(3)Pandor from the race of alien species Prypiatosian-B. Main ability is Pyrokinesis.
(4) Andreas from the race of alien species Talpaedan. Main ability is Terrakinesis.
(5) Ra'ad from the race of alien species Amperi. Main ability is Electrokinesis.
Due to the fact that these aliens represent the elements, Aggregor decided to absorb them to get the fundamental level of power.
Of course, Ben and his friends tried to stop him. But they were too late.
Rex: Guys, now you got know about Aggregor. Now to the next topic that is Map of Infinity.
The Hakuryuukou and Slash Dog continues his explanation.
The Map of Infinity is an alien artifact created by none other than Professor Paradox.
It is a complete map of space-time, extending through 17 dimensions. Whoever has the map could travel anywhere in the universe, even to the Forge of Creation.
Knowing how dangerous the Map of Infinity could be if it fell into the wrong hands, Professor Paradox divided his creation into four pieces and stored them in safe places throughout the universe. The parts were hidden in Mikd'lty, Piscciss, Legerdomain, and Perplexahedron.
But Aggregor successfully got all the four pieces of the Map.
The forge of Creation is the homeworld of Celestialsapiens. It is a beautiful outer space-like realm with no identifiable borders or land masses.
It is outside the universe. It is a place hidden to everyone except Celestialsapiens, Professor Paradox and anyone with the Map of Infinity.
However, Professor Paradox is not allowed to be within 500 light years of the Celestialsapiens. Therefore, he is not allowed to be in forge of Creation.
Ben and his friends constantly tried to stop Aggregor. But over and over again, they failed.
Rex: So that I am here to stop Aggregor to become omnipotent. Also I want to see how strong opponent he will be?
Rex further went into the barrier to the other side.
Now that Ben and his friends have only one last chance to stop Aggregor. Luckily for them, a powerful ally came to their aid.
Hope you all like it. Please continue to give power stones for more chapters.
