Darmanitan in Zen mode switching to normal mode?

Question

If a Zen mode Darmanitan healed itself by potion, Heal Pulse, ect, then would it switch back to normal mode? Just wondering since I don't have one with Zen mode.

Answer 1

It will go back to normal form.

When Darmanitan's HP drops to below half, it will change into its Zen
Mode at the end of the turn, which is a dual-type Fire/Psychic form.
If it loses its Ability, or recovers HP to above half while in its Zen
Mode, it will change back to its Standard Mode. Darmanitan will revert
back to Standard Mode outside of battle and enters battle in Standard
Mode, even if its HP is below half.

Answer 2

Yes.

It reverts back to normal form right after it's health goes above 50% again.

Hope I helped!
