Roar!
Immortal screamed to transform into a humanoid wolf with large blade-like claws that hacked and slashed into the Invader System, wounding it severely.
"Help me!" The Invader System shouted in alarm, "Why the heck is Immortal still this strong?"
Boom!
Apocalypse arrived at the scene, punching Immortal in the face to send him flying, muttering in shock upon seeing its fist crack in response, "What…is happening?"
"Regression!" Apocalypse turned around to ask in alarm, only to see Regression sweating buckets in a fluster.
"Even after losing his sentience, Immortal somehow managed to siphon my powers to regress himself." Regression stated in alarm, only now realising that Immortal wasn't as dumb as he seemed. Or at least, he was able to unleash a last-ditch counterattack.
"He's…regressing?" At this word, pretty much all Grade 3 Systems paled in fright.
