Ken's eyes changed from normal eyes to Rinnegan's eyes. This was very weird because Ken didn't even have a Mangekyo Sharingan to begin with. According to the norm, only after Eternal Mangekyo Sharingan could one get to the Rinnegan, but it was different for Ken because he was special.

Ken didn't get to be the Junchuriki of Ten Tails, and thus, in order to compensate him, the system decided to give him powers in the most weird way possible. According to the system, Ken would get all the powers of Rinnegan, i.e., the ones that Nagato used with all the paths. But that also meant there were different levels of power for the system.

And according to the system, some of the powers of Rinnegan were lower as compared to the Mangekyo Sharingan of Obito. The space-time jutsu of the kamui dimension were much more powerful than the Rinnegan's, and thus, for the system, Ken got access to some of the Rinnegan's powers.

So for the first time, Ken could get access to Rinnegan's powers, and he wanted to use them. Luffy came up and was about to strike when Ken stopped him.

"Don't. I want to try my new powers."

"Are you sure?" Luffy asked.

"Yes," Ken replied while showing him his eyes. Luffy hadn't seen such eyes before, so he let his brother take the reins. Ken put his hand up and showed his palm toward Blackbeard. He was ready to show the same old move to the Straw Hats but was confused with what Ken was going to do.

"Bansho Tenin" (Almighty Pull)

As Ken said these words, Blackbeard watched himself in horror. He was slowly being lifted off the ground! Gravity had just changed his course for him. Horrified Blackbeard, in order to stop the course, used his dark fruit power to cancel the pull with which he was lifted up, but nothing happened.

The dark fruit could only pull things towards itself; it couldn't repel things. Repel was only possible if he had sucked something. But this wasn't the case here. But Blackbeard didn't get much time to think before he pulled with extreme force. Using his dark fruit only made his pull much faster.

In no time, he was inches from Ken when Luffy came up between Blackbeard and Ken. His hands were laden with armored haki. Before he knew it, Luffy delivered a full Haki-laden punch to Teach, and that too right at the abdomen of Teach.

He coughed out blood instantly and was then thrown back to the same place where he came from with incredible speed. Ken smiled when he saw that. After all these years, both of them had a proper understanding of each other and could fight together with perfect synchronization.

Luffy's attack was so powerful that Blackbeard was on the verge of losing consciousness. Luffy didn't use his devil fruit power, so he couldn't negate the powers like he always does. Ken didn't stop there. He pointed his palm again at Blackbeard and said,

"Shinra Tensei." (almighty push)

And just like Ken's previous move, Blackbeard felt a force. But this force wasn't a pulling force but a pushing one. He was pushed onto the ground so fast and so heavily that his face and the shape of his body seemed distorted. The ground itself started pushing out of its place in order to accommodate the huge gravity push.

Blackbeard was questioning his life as he was being treated in the worst possible way by almost nobody. When he was sent hurling to the ground from a punch, he didn't expect that someone in the starting Grand Line would have Armament Haki.

With his observation, he was able to sense that a powerful punch was coming, but there was no way he was able to stop himself when he was flying at such a fast speed. He knew Haki, but not to such a high level that he would be able to make his body like Vergo's. He just knew a bit of it and was convinced that his Devil's Fruit was going to save him.

But the punch just proved him otherwise. The punch was already hard on his body, and the Shinra Tensei very much made his bones crack. Ken's attack was vicious and full of malice, and he actually had a slight intention to kill him right here.

After a few seconds, Ken stopped putting more chakra into the attack.

"Damn Ken, what the hell was that?" Ussop asked, as he felt fear from how he toyed with this ugly guy.

"My Rinegan has awakened, and I can only do the pushing and pulling as of now." Ken replied.

"Only? There are more moves?" Chopper asked.

"Yes. The Rinnegan eyes were attributed as godly, so in a way, the power is a little off the charts."

Everyone's eyes were on Ken, as they could not imagine how powerful their eyes were. Luffy had already spoken about the Sharingan, as he knew about it during his time as Hiruzen. Hiruzen had learned a lot thanks to Itachi. So he gave everyone a general idea that once Ken awakens his Sharingan, it will be a different ballgame.

"You have awakened your Sharingan?" Luffy asked.

"No, Rinegan is the higher power than Sharingan. My awakened Sharingan is a little bit broken. Once I awaken it, nobody will be able to touch me." Ken replied.

"What is it? Tell us.. Please tell us." Chopper, Ussop, and Luffy had stars in their eyes as they wanted to know what power the Mangekyo Sharingan had. But Ken refused to tell. Cricket and his friends had question marks over their heads, but they didn't ask because they could feel that whatever Ken was talking about might be a crew secret.

Meanwhile, Blackbeard slowly got up on his feet. He had a broken hand, a broken ankle, and a few cracked ribs. He got up slowly but coughed up blood. He wasn't in a very good position.
