Lol, sorry sorry. Yes, Akuno is Dark Kai, as well as Aratame. I get mixed up when writing about him, so I often switch between names accidently. I was hoping it was obvious, but I was planning to explain this later on in OoS.

In DBZ, it was explained by Nappa, I think, that the Namekians were great magicians, and could create things of enormous power, things that were beyond their level of strength. So, on Original Namek, there were the Original Dragon Balls, the ones that had eight rather than seven Balls. The Namekians managed to capture Dark Kai within the eighth Dragon Ball, and so that's how he was trapped.

But Serroli, on the other hand, was incredibly strong, atthat point in time stronger than Dark Kai, and so the Namekians had to sacrifice their lives to trap him. He was trapped on the planet, he could do whatever he wanted there, except leave. The entrapment was only broken when Goku and Vegeta landed there.

Dark Kai is freed after Goku and Vegeta find all of the eight Dragon Balls and summon the Dragon. They do so to leave the planet (that's what they're doing during the TSS saga; trying to get off). Serroli had no idea of Dragon Balls, the only one he knew about was the one that Dark Kai was trapped in. That's why he couldn't leave.

I've been assuming you're familiar with the entirety of ST, so that's why I've been elipsing stuff but no matter.
