After seeing his status, he used destruction energy in his body. Destruction energy destroyed his body while with perfect immortality he got healed. And with zenkai boost He started becoming stronger. He was doing this for sometime when he smelled some one enter his cave.
He opened his eyes and saw it was a masked man. The masked man, then 'ordered' him: Hey you, I am madara and I want you to become my contracted beast.
Acnologia: You are not madara and who r u to order me like this?! Do u think u can use your sharingan to go to your dimension, obito.
obito lost his self control and tried to attack acnologia. He knew this was not an information that could get out or all the plans will be destroyed, so he took the chance, He made hand sign and used fire style flame emperor. The ball of fire hit acnologia and destroyed his mountain.
Acnologia got angry because his mountain was destroyed. When mountain was destroyed everyone from akatsuki came out to see what was happening. even black zetsu came out. They say obito standing in front of a black dragon. They thought what could destroy the cave. That's when hidan ask something which caused everyone to become more attentive.
Hidan: Is it possible that madara attacked the dragon and destroyed his mountain in process.
Then they saw dragon stand up on its hind legs. Then heard him spoke.
Acnologia: It seems like this world need some terror to be reminded again why you don't mess with I, ACNOLOGIA.
As the members of akatsuki heard his first line they didn't took it for much they thought he would be as strong as kayubi. But when they heard the Dragon's name, there smug faces changed completely. and Black zetsu he knew this time they are doomed.
As everyone was thinking something, Obito knew he fucked up really bad. Who knew he destroyed the mountain of DRAGON OF DOOM. And he was the one who awakened the DRAGON OF DOOM, so it is his fault to let this DOOM BRINGER come back to terror the world again. but that was all for later right now he needed to run. But can he?
Acnologia started to release all his power and and whole world even those who doesn't practice any sage arts or ninja arts were able to sense it.
Every toad is looking towards a certain direction. They can feel that everything is trembling. Not just earth and sky, but they can also feel nature energy dread. Nature's energy dread meant that the world is threatened to be destroyed.
Every toad look toward there ancestor, and they can see he is trembling in fear, as if something terrible has awakened.
Fukasaku asked: ancestor what is it that the planet dread and why are you trembling?
Gamamaru: fukasaku, use reverse summon and summon jiraiya here, we need to let the world know The DRAGON OF DOOM 'ACNOLOGIA' has awakened.
White snake sage: He has awakened.
This cave was also silent with dread right now. They can feel that even world fear the being which has awakened.
Slug sage: Who can make his angry?! Summon all our contractor we need to tell them about acnologia.
and same could be found happening in all small and big animal summons area.
at this time where acnologia mountain used to be.
Everyone there has lost all the motivation to attack. They can tell that world is threatened by the dragon before them. They can feel natural energy telling them not to do anything reckless. It telling them to kneel and apologise and give up there lifes.
obito can do anything. He knew he fucked up big this time.
Acnologia was releasing his aura uncontrollably. while he was doing so he asked system to show his status. After doing his training in cave he wants to see how much he improved.
system: Yes host

LIFE SPAN: INFINITE

After seeing his status he was very happy. He then stretched his claw toward obito and picked him up and threw him toward the sky. Then he took a deep breath. as everyone watch in amazement, they saw dragon took a deep breath and Endless energy of all kind of elements started to form a sphere in his mouth. Then dragon spoke.
Acnologia: CHAOS DRAGON ROAR!!!!!!!!!!
Then the roar shot at obito who was in sky he used his power to go it different dimension. But as the roar hits him his dimension was destroyed and he was destroyed as well. he had regretted why he provoked the dragon.
Everyone there watched in amazement as his roar destroyed obito and continue to travel until it hit some planet which it destroyed as they could feel a blast wave travel to this world.
Acnologia looked satisfied. As he was about to fly away he heard system.
System: Mission is handed out would host like to see?
Acnologia: Yes tell me what is the mission and its rewards.
system: MISSION: UNSEAL KAGUYA AND MAKE HER ACCEPT YOU AS YOUR MATE

System: Would Host like to accept the mission or not.
Acnologia thought about it for sometime and realized he liked kaguya, otherwise he wouldn't have stayed with her for 20 years. So as a dragon he made up his mind to make kaguya accept him as a mate even if he has to use force.
