4 arms? Could he be a hint for Kintaro? I don't know another character than Kintaro and Goro.The leak mentioned how The Kollector was a cyborg, but "not how you would expect"
It also said he had four arms. If you look at his portrait, it looks like something is behind him. It the same color of blue as his skin, so maybe he has weird arm thingies on his back?
Could still be a cyborg, but made to look organic?
