So they used that power to enhance the restraints and everything else thus he was imprisoned. While Jason was saved by a Healer she had gone to Savage Island to look for any survivors. He was the sole Survivor and they fell in love. While imprisoned Eternal God Savage had countless experiments conducted on his body and mind daily they were studying him. Trying to find out why he was so unique and why he was the way he was. They were also trying to find out weaknesses and measure his might so they could reinforce everything to prevent his escape just in case the Vodoo failed. They needed more ways and methods to keep him contained they constantly had Vodoo masters enter that Cell to reinforce the Vodoo when one Vodoo Master was too exhausted they left. As another continued and it would repeat constantly as they would keep going in rotation until the Vodoo power overwhelmed the combined might of all of Eternal God Savage. This was perfect as the weakest of Vodoo made him powerless so Vodoo of that scale was perfect allowing more research. They eventually managed to reinforce everything to a level that surpassed his might thus restraining every aspect and trait of his as well as having the Vodoo in place left him fully contained. They were safe to conduct research on his evolutions and rates of evolveing as they tried to figure him out completely. Naturally this place was a total Black site highly classified to the point that all the other such covered up stuff all seemed well known to the public.
