i’ve been wondering a while for this, is it strong enough to decimate a planet or dealing serious damage to the planet??
Depends on the size of the planet and what it is made of.
Reschard V in Placid was decimated, all but wiping out the Intaki colony there, in YC108 (2006).
My understanding is that it has since been confirmed to have been the result of an Avatar doomsday strike.
An old AOE Doomsday, specifically, which aren’t that commonal anymore as far as I’m aware, but yes.
