Tony immediately went to a base of operations of Stark industries in Vienna and promptly stripped naked as he arrived in a lab and a glass cabin opened while he stepped inside of it.
[Performing a full body scan to track and simulate the mutation]
Came the voice of Jarvis as a blue light engulfed him
[Mutation Found - Radioactive version of extremely pure and potent vibranium with unknown black colored liquid found merging with the D.N.A]
[D.N.A restructuring is synchronizing the quantum vibrations with that of the radiation.]
[Simulating the Mutation with 2x Speed]
[No Physical changes]
[Ability to control vibranium - 80% Probability]
[Ability to absorb and release energy particles not superior to the Radioactive mineral - 80% Probability
Unknown effect - Can only be found out after the actual mutation]
After Jarvis gave it's prediction about his mutation, Tony was confused as he already had these powers which were given to him by none other then Bast herself.
"Bast? You there?"
Said Tony, trying to make a mental connection with the divinity.
"Yes Tony, I am here. Speak, what is on your mind?" came a less frightening voice of a female panther in Tony's mind with which he saw an illusory body of a White Panther.
"What is happening to me? Didn't you gave me these abilities already?, So why I mutating and gaining the same powers?" asked Tony with a frown.
"Oh, I can sense now, Your body has bounded with vibranium. Now you don't need my powers. Well this is probably for the better as now I can give these powers to a worthy Black Panther while you will still retain your powers as they have become entirely yours.
This must have happened when you came in contact with the core of the meteoroid which struck wakanda centuries ago."
'No shit you stupid cat' Thought Tony as he looked at this giant ball of fluff and chatted with her a little about Heliopolis before saying his goodbyes as to not give her an impression that he only cares about her powers.
Tony although was still happy at this turn of events as he had started to feel faint energy particles in atmosphere around him.
He started to experiment with them and soon the sun came down and back up again.
Tony was still in his lab experimenting with a glowing object when a call interrupted him.
"Yeah Steve?"
"Hey Tony, The meeting starts at 10. Where are you?"
"Oh, I'm on my way, You at the S.H.I.E.L.D's facility ?"
"Yeah, So you coming?"
"Yeah yeah, be there in a minute." replied Tony as he disconnected the call.
'Jarvis, check now. Does the EMP work on my armour?'
*krrrsssnggg*
[No Sir, Your Nanosuit is now ineffective to EMP's frequency]
'Good, Now let's see Rogers...I want to see his face when he activates the EMP to disable my armour but nothing happens.'
Although Tony had Vibranium and Adamantium both but he had other plans and didn't wanted to use them till he got the Smart metal from a symbiote, and hence kept himself from immediately making a suit from them. But since his body was now mutated, he had upgraded both his weapon and suit, aside from his hundreds of trump cards.
"Natasha will betray me, Barnes will be revealed as my parent's killer, Vision will almost kill Rhodes and Ant-man will have a brilliant idea of going in my armour plates and disabling my armour from the inside. Well that is not possible now since I have a nanosuit, I can malfunction Rhode's armor and let Vision hit directly in his vitals and using his death as a reason to capture Vision and extract the mind stone I mean, I will have full control of his body. I can also scan Ant-Man's suit during our fight which will allow me a little insight in his suit. I can make a better one then Hank. And about Natasha, I don't know why she and Clint are even in the avengers but I can dispose of them. Trash don't deserve such a position."
After Tony had recounted the things which will happen and what he can or cannot do, a swarm of particles creeped up on his body which immediately turned into a red and black nanosuit with blue lights all around it.
"Let's get this party started."
.

.
.
Tony arrived at S.H.I.E.L.D's facility in Vienna where Natasha, Steve and Sam were waiting for him.
Tony let everything flow as they did in the movie and as soon as he got the news of a bomb blast at the diplomatic conference, he rushed there with the other Avengers to find that many UN council members have died and many were heavily injured.
Tony immediately made his way through everyone and arrived in front of T'Challa who was sitting motionless beside T'Chaka's body.
"He's still alive!" Screamed Tony as he instantly checked for T'Chaka's vitals with his multi-purpose Stark Card made out of clear glass which brought some light in T'Challa's eyes.
"What? But his heart has stopped. Are you sure Tony?" questioned T'Challa as he looked at Tony with hope in his eyes.
"Yes brother. Looks like the Heart herb has saved him but I immediately have to bring him to my lab and operate on him." replied Tony with a firm voice as he lifted T'Chaka with one hand and took out the Heart-Shaped herb with another.
T'Challa was not surprised to find Tony in possession of such a secret herb and reluctantly took the herb from him as he also took the ring of his father. Tony patted T'Challa's chest pocket where he had put his vibranium reactor and immediately shot towards the sky with a blinding speed.
This whole interaction was done within a couple minutes and as Tony disappeared, Natasha came at the location where Tony had just been to find neither Tony or T'Challa.
.
.
.
Within an hour, The footage of Barnes planting the bomb was shown to the authorities.
Steve had a horrified look on his face as Natasha tried to comfort him, unknown to them, T'Challa, in his new Black Panther suit was too watching all this with his kimoyo beads.
.
.
.
.

Tony was back at his lab, but this time he was operating on T'Chaka.
'I can heal him right now but that would show that he was not that injured in the first place. Jarvis, keep him in a comatose state for at least a week. I will ignite T'Challa's anger and use him to hunt for magneto while I go about my plan.'
Said Tony in his head while T'Chaka's body descended inside the table he was lying on after which it was filled with some viscous liquid and was then sealed off.
As Tony was thinking about what to do while T'Challa captures Barnes, a notification came from Jarvis which made his eyes flash with red light.
[Symbiotic lifeforms detected. 4 Symbiotes have just been registered in a space probe of 'Life Foundation' and are preparing to come back on earth]
"Intercept the probe! Hack it."
Tony was feeling excited as now he could extract the Symbiotic Smart metal. He wasn't crazy enough to bond with them, but he would make sure to kill them and extract their constituent matter for his Symbiotic armor.
Soon, with Jarvis's control, the probe landed in a desolate land where Tony was waiting in his suit and as soon as it landed, Tony immediately extracted the Symboits and destroyed the probe on a particle level with his supreme vibranium repulsor and extremis ability.
Tony was back in his lab again and casually placed the four vials containing the Symbiotic life-forms on the same table T'Chaka was in.
"Start the extraction process." Said Tony as a live feed of Bucky running and Crossbones arriving at the bomb site was showing on a screen.
.
.
.
.
.
Black Panther had soon caught Bucky but due to the amount of destruction he did in its wake, he, with Barnes, Steve and Sam were surrounded by countless S.H.I.E.L.D agents and were taken to the S.H.I.E.L.D facility.
[Experimental project #4. Integrating Adamantium, Vibranium and Liquid Smart Metal with the improved reactor]
Came Jarvis's voice from Tony's lab.
So to answer some questions from comments. Tony's physical power, although not at the level of Hulk yet, but he is pretty powerful. And No, This doesn't make him OP. If you've read the comics, you'll know the powers of Celestials who could destroy planets as if chewing on chimichangas. Marvel Multiverse is far too big and far too OP.
There are actually way too many OP characters that haven't even been introduced yet. Some of were even worked with avengers. Go read comics.
