Then again, if it's possible for Tobio Ikuse to become a "Scythe-Wielding Wolf-Man", then I guess Sirzechs can actually "turn into" a pure mass of Power of Destruction. Although I still strongly believe that this "True Form" is a result of his immense power, and magic talent.

Oh. And as for Ajuka, I'm not sure he really has a "True Form" like Sirzechs. Sirzechs is known for his Power of Destruction (which destroys all things), and Ajuka is famous for his Kankara Formula (which takes controle of all things). So maybe Ajuka just "powers up" in order to use his Kankara Formula on a grander scale.
