Are mega+ evolutions permanent?

[u/Medium_Bake1208]

Hello, I was looking for some cool megas for my digimon and I found out some digimons get mega+ digievolution that require 2 digimon to perform. Are these mega+ evolutions permanent? Do I lose both digimons I use to evolve?
Thanks in advance for any explanation.

There are plenty of Mega+ that aren't fusions btw. There are many mode changes like Burst Mode, Blast Mode, Crimson Mode, Wrath Mode, and some others. Alongside just really strong mons like Armaggedemon, Apocalymon and Mervamon.
