The Brutal Leviathan is far stronger than its previous form. It enjoys watching the fear of other Hypothetica, and, to help itself, it has become darker and developed bright markings and eyes, so the others see only a pair of red eyes in the darkness before it lunges at them. But instead of eating them instantly, it 'plays' with them like a cat does a mouse, chasing one then twisting away at the last second to chase another, before finally deciding on some to predate. Its spikes and pointed tail are useful weapons and also add to its frightening appearance, and its colours don't hurt it, as it has no predators...yet.
It will even attack the far larger Peaceful Leviathan, as its adaptations allow it to strike faster and harder than the Peaceful Leviathan can.
