Grizzly Nyah

This creature is a colossal cat-shaped humanoid fitted with six eyes and jagged fangs. Fully grown specimens can stretch as tall as twenty meters, and its recorded stats put the adult at roughly two thousand centimeters in height and a staggering seventy tonnes in weight.

Documentation on its temperament is thin, but the beast behaves much like other Mysterious Beings, showing clear hostility toward people.

The offspring alone proved dangerous enough to overpower several A-Class heroes, downing Peach Terry and Heavy Kong and slamming Genos hard enough to send him through a wall. They kept pace with Lightning Genji's speed and sat around the Tiger-level tier, since A-Class fighters like Stinger and Genji could take them on. The mother was fearsome enough to make Stinger flee even though he had severed her children's arms, yet Saitama ended her almost instantly.

Her enormous bulk gave the parent tremendous power, and even a juvenile could crack open the ground with a paw and hurl Genos through concrete. The young could shrug off a few of the cyborg's strikes, roughly match his pace, and stay nearly silent when needed, slipping past Genos' sensors for a time despite his advanced detection gear. Unusually for a monster, the species can reproduce, and its attacks include raking Nail strikes.

In the extra chapter, an escaped Grizzly Nyah stirs up chaos across Z-City and soon gives birth to two more. One cub disables Heavy Kong and Peach Terry, while the other is beaten by Lightning Genji and Stinger, and the first is then put down by Genos. Sensing her offspring's defeat, the mother appears just as Saitama is trying to rescue Torako, the cat belonging to a Hero Association handler's daughter, and he eliminates the monster with one blow.
