The Mutant Killer Whale That Ate the Tremor-Tremor Fruit, Its Hatred for the Mutated Giant Octopus!

But this was not the time to focus on that. They still did not know whether this Mutant Killer Whale was friend or foe.

Before the Reiki Revival, Killer Whales could even be considered friendly toward humans. Whenever humans encountered danger at sea, nearby Killer Whales would appear as "lifeguards." There had been virtually no hostility between the two.

But now that the Reiki Revival had occurred, no one had yet verified how mutated Killer Whales treated humans.

However, considering that most Mutated Beasts they had encountered had been hostile toward humans, they did not dare let down their guard.

"Roar!"

The Mutated Giant Octopus looked at the Mutant Killer Whale as though it had seen a mortal enemy. Its enormous tentacles, carrying terrifying force, slammed straight toward it.

"Klak klak!"

The Mutant Killer Whale did not hesitate either. It leaped and turned through the ocean, then smashed forward with a swing of its tail.

"Crack!"

"Crack!"

"Crack!"

Sounds like shattering glass rang out. A white halo covered the Mutant Killer Whale's tail, and the air where they collided shattered outright, forming Runes like spiderweb cracks.

"Rumble!"

Amid a deafening roar, terrifying energy erupted from their collision. The surrounding seawater exploded downward, revealing a massive hollow.

"The Tremor-Tremor Fruit?!"

Huo Yu stared at the Mutant Killer Whale in disbelief. She could not be certain whether the black mist used by the Mutated Giant Octopus had anything to do with the Dark-Dark Fruit, but the ability the Mutant Killer Whale had just used was definitely the Tremor-Tremor Fruit!

She had seen the white halo covering the Mutant Killer Whale's tail and the spiderweb-like cracks in the shattered air perfectly clearly.

Even if the killer whale had Awakened an ability related to Vibration, it should never have been able to produce effects
