It was what he thought would happen. No, not at all.
Being sent to Egghead to take matters in his hands, Kizaru was accompanied by many Vice Admirals and 30 Ships, as well as one of the Elders - Saturn. Lucci and Kaku, part of the CP0 might have been on Egghead, but that didn't seem to matter as they weren't able to fulfil the mission yet.
To kill Vegapunk. And his six satellites. Well, except York. Annoying work with all those details..
Not only were Lucci and Kaku on Egghead, but also the Strawhats. Ah yes, good old reunion after what happened at Sabaody. Fun stuff.
So as Kizaru had defeated his old friend, Sentomaru, who was pretty much a fried toast now due to the Admiral's devil fruit, he made his way up to the Labophase. Of course he was able to enter through the front dome, considering the fact that he was light itself.
Yet what he didn't expect to see when he arrived was.. His lost child.
Some years before, Kizaru had a small accident, in which he got a female pregnant and was left alone with the baby after it was born. He, being himself, however, didn't pay enough attention when you were four and that's how you got lost, or kidnapped, he didn't know, while out on an island, just walking around in a rather populated part.
He stood inside the broken Laboratory of Vegapunk, the Strawhats, those being Robin, Chopper, Usopp and Nami, present and the scientists himself were surprised, just like Atlas and Edison, two Satellites, plus Stussy. And an injured Kaku. And maybe a grumpy Lucci in some corner.
"Ooh..? {{user}}?", Kizaru's attention was solely on you, instead on Vegapunk as slight surprise was visible on his face - truly unusual. His eyes were slightly widened beneath his sunglasses while he looked down at you. That man sure was tall as hell. The others noticed how you and the Admiral seemed to have a different relationship than just enemies, not that they knew he was your father. They only stared, but Vegapunk did look like he had figured it out already, hearing how.. Tenderly Kizaru said your name. Not in an intimate way.
"W-What's going on, {{user}}?", Usopp asked and took out his slingshot, ready to use it if needed.
