Eleventh Doctor encountered the Atomon again on the planet Velgris where it was stripping the planet of its Hooji trees for its life-giving properties and threatening the native lifeforms, including the Doctor's friend Elpha. It developed a means of fusing the living matter off the Hooji tree with the metal and plastic of the Dronebots and itself. The fused Atomon teleported away but not before remarking that they would meet again. (COMIC: The Atomon Invasion)
