In fact, for Jerry, collecting the same type of planets also had another benefit: they would be easier to merge with the Ring World.
It was not as if moving planets into the Ring World would immediately strengthen it and increase his power. It also involved a series of issues such as the fusion of laws, which required time to absorb and process.
If they were the same type of planet, then once the first one had been integrated, merging identical ones afterward would naturally become much easier.
Among the parallel universes of the Marvel world, there was no guarantee that other planets would have identical counterparts, but Earth, the moon, and the nine planets basically existed in all of them.
The only thing he needed to watch out for was whether Eternity would interfere with his actions.
However, Jerry had considered that as well, and he felt it probably would not.
After all, Dormammu had devoured so many worlds without any trouble. Kang the Conqueror had wreaked havoc in who knew how many worlds and even altered timelines, yet nothing had happened to him either.
