Though it has a gentle disposition, it’s also very strong. It will quickly freeze the snowball on its head before going for a headbutt.
Galarian Darmanitan-Zen: Anger has reignited its atrophied flame sac. This Pokémon spews fire everywhere as it rampages indiscriminately.
Darmanitan takes this form when enraged. It won’t stop spewing flames until its rage has settled, even if its body starts to melt.
So, it's like a reverse Zen Mode. Instead of becoming calm it gets fired up.
