The Big Sacrifice
Thor understood what Richards was saying: they needed a vessel to contain Onslaught. Without any thought, the Thunder God flew into Onslaught’s energy form and sacrificed himself, in hopes that his mighty body would be enough to absorb Onslaught. Thor landed inside Onslaught’s body and screamed in pain, it didn’t work the way he thought. Reed believed that the plan was useless if Thor did the job alone, for he didn’t have enough mass. That was all the other heroes needed to hear. Making their final goodbyes to each other, they jumped into Onslaught’s energy form one by one, effectively weakening him. The Thing and the Human Torch, most of the assembled Avengers, Iron Man taking Dr. Doom along against his will, even Bruce Banner‘s human half – they all entered Onslaught and bound him to their combined mass.
The atmospheric changes around them told Mr. Fantastic that the plan was working, but still more mass was needed – though not every mass. When Quicksilver, Crystal and Wolverine rushed to jump into Onslaught next, they were held back by Reed. He explained that since Onslaught began life as a mutant, a mutant genetic pattern would give him the perfect means to live again! The Scarlet Witch seemed to be protected by one of her Hex spells when jumping in, but Reed didn’t want the rest of the mutants to dare make contact with Onslaught. It was up to the human heroes to do the job. Quicksilver felt a bit relieved, until he realized that this wouldn’t exclude his wife Crystal, an Inhuman, from giving her life. Using her elemental powers to blow her husband away, she too entered Onslaught. As the only non-mutant heroes left, Mr. Fantastic and the Invisible Woman ordered the X-Men to give everything they had to blow Onslaught out of existence once they had followed the other heroes. Holding each other‘s hand, the Fantastic Four’s couple then threw themselves into the belly of the beast too.
