What makes Grognar even more special is his unusual amount of psychic energy inside him. Psykers report to have traced unimaginable amounts of energy. Grognar eventually catches on to this and starts using his immense amount of energy to good use. In battle, he can use his psionic power to literally burst open the minds of any psykers that try to invade his or his boys minds. On top of that already incredible power, he is able to crush enemies and explode vehicles simply by using his mind to imagine it. Most psykers either use these kinds of powers sparingly or not at all due to the amount of energy required and the potential risks and backlashes involved in using these abilities. He is even rumored to topple over titans simply by willing it to be so.
