Thor had no idea Loki was watching him from nearby. He was completely immersed in the fight. Though he no longer had Mjolnir and had lost his divine power, the giant he was facing now was considerably weaker than a Frost Giant.
After Bill transformed, his strength increased greatly, but his agility plummeted. Thor wasn't foolish enough to match his strength head-on. Instead, he relied on his nimble movements to circle the giant.
After transforming, Bill's body was covered in a layer of tough, rubber-like muscle. Ordinary attacks had little effect. But Thor had plenty of combat experience. After a few attacks showed him just how tough the guy was, he changed his target.
The ankle was an extremely vulnerable joint, bearing the entire weight of the body. A careless step could sprain it, or even cause a fracture. Thor didn't attack Bill's tough muscles. Instead, he waited for Bill to turn and balance on one foot, then poured all his strength into a kick to his ankle.
Even without his divine power, Thor was still several times stronger than an ordinary person. His kick, delivered when all of Bill's weight was on one foot, inflicted serious damage.
Bill's ankle was kicked into a right angle. The excruciating pain made him lose his balance, and his three-meter-tall body crashed to the ground.
The ankle joint had come completely apart, and the bone was even shattered. The heavier Bill was, the greater the damage to his ankle.
Having won with ease, Thor was about to press his advantage when he saw Echo in danger. Echo's body was covered in black scales that could stop bullets, allowing her to fight through a hail of gunfire without fear.
But the energy whips formed from Nicole's hands had far more destructive power than bullets.
