Injustice 1.5 - Chapter 4: I live, again
"Garfield Logan, the Teen Titan known as Beast Boy, was dead. Killed by an explosion of all things, disappointing. The funeral was amusing to watch."
Trigon being omnipotent, was aware of the events on Earth, the demon overlord also made note of his daughter's reaction to the news of the green one's death, she didn't take it well.
The more Trigon thought about it, the more he realized he could make this work to his advantage, after all, Raven now serves him.
Garfield's coffin had been buried just over a week ago, Trigon hadn't attempted typical demonic possession often if at all but for someone as potentially powerful as Garfield Logan, Trigon was willing to make an exception.
Gaining control of the body was easy since he was already dead, as Trigon possessed Garfield's corpse, the skin fading to red with black demonic tattoo-like markings, another pair of eyes sprouting above his regular eyes, both pairs glowing yellow, the green hair fading to a silvery gray, and red, clawed hands dug their way through the coffin lid and eventually popped out of the ground, and he pulled himself out of the dirt.
Tri-Beast rising from the grave.
And with Trigon in control, a sinister fanged smile on his face.
Demonic powers and shapeshifting created a deadly mixture.
