Tatsugiri were Pokémon extremely sensitive to danger in their surroundings.
Although they were hardly weak in battle and possessed the naturally noble power of dragons, their poor stamina meant they were unsuited to prolonged fighting in the wild.
Rather than hunting, simply surviving in the wild became their foremost priority.
Fortunately, these little creatures had sharp minds and gradually developed their own unique fighting style.
Piloting a Gundam!
Through their mutually beneficial partnership with Dondozo, acting as their external brains, Tatsugiri gained a firm foothold in Casseroya Lake, where powerful Pokémon abounded, and their population flourished.
One particularly fortunate Tatsugiri even discovered a special plant in a secluded cave along the shore of Casseroya Lake. Eating it granted terrifying physical strength for a short time.
But being as clever as it was, Tatsugiri naturally understood that this power would do little for it personally.
So it made a bold decision-
It would use this special plant to raise an exceptionally powerful Dondozo, making it the undisputed king of Casseroya Lake!
As for itself, it only needed to stay behind the scenes and be a good Gundam pilot.
From then on, under the combined influence of Dondozo's strength and Tatsugiri's intelligence, order gradually emerged in the once-chaotic Casseroya Lake. The surrounding ecosystem became increasingly well organized, and more and more Pokémon accepted this unusual Tatsugiri and Dondozo.
This was a good thing for every Pokémon living nearby, and they voluntarily joined the orderly system led by Dondozo and Tatsugiri.
Thus, Casseroya Lake today was a place bursting with vitality, where all living things flourished.
Taking inspiration from stories of Palafin, the nearby Pokémon affectionately called this "king" who had established order in Casseroya Lake-
Tatsugiri Hero!
