Notable Attacks/Techniques:

Alternate Forms:

- Incomplete Form: Demonbane releases Cthugha out in the open, covering everything in an expanding wave of white heat. The technique had enough power to vaporize to annihilate Gondora, vaporize the majority of a small island and reduce the distant beaches of Insmouth to molten slag. Obviously, this technique is nearly as hazardous to Demonbane as it is to the enemy. Only the combined strength of its armor and barriers allowed Demonbane to barely but survive this attack, at the cost of sustaining massive damage in the process.

- Plasma Gun/Pistol Form: Weapon manufactured by the Hadou Financial Group. It's a giant pistol large enough to fit in Demonbane's hands and designed to contain Cthugha's power. Its attacks were noted to have 1/10th of Cthugha's power albeit concentrated into single stream of plasma. While practical, the pistol appeared to malfunction at its first use thus Al Azif refused to rely on this weapon again.

- Human Form: Cthugha is capable of assuming a human form to communicate with its master. In that state Cthugha had shown little feats aside from being slightly superior to her sister, Ithaqua.

- Gun Form: Using the Tyrant's weapons as the base, Kurou managed to create a weapon that can finally use Cthugha's powers safely. The result is a clip-fed automatic pistol that can fire multiple exploding shells at rapid succession or release streams of concentrated plasma energy. The latter attack was strong enough to critically damage Kraken or effortlessly blow up dozens of Destroyer Robots in a straight line.

- God Beast Form: Using special bullets with the powder of Ibn Ghazi, Demonbane is able to materialize Cthugha's true form to unleash all of its power. In terms of sheer power, God Beast Form is comparable to Cthugha's first use (incomplete form), albeit with far more control. In the shape of a fiery beast, Cthugha bursts out from the gun's barrel with heat surpassing a nuclear explosion. This technique was strong enough to destroy many hundreds of minor god with power and appearance similar to Dagon, while leaving the sea intact. Apparently, this new form of Cthugha can differentiate between friend and foe, only burning those whom Kurou views as enemies.

- Combined God Beast Form: Demonbane releases the spirits of both Cthugha and Ithaqua at once. The two God Beasts rush out from the barrels and meet mid-air, condalescing into one huge white explosion. The said explosion was large enough to cover the entire space above Arkham City in the skies. Alternatively, this explosion can turn into countless homing energy blasts, to destroy an entire army of enemies in a single move.

- Personal Gun Form: Cthugha's gun can also assume a more compact size, small enough for Kurou to wield in person. In that form Cthugha has the same abilities as it does in its normal Gun Form, expect the attacks are much weaker. Albeit less powerful, a single bullet from Cthugha is strong enough to blow up a mass-produced Destroyer Robot. With multiple consecutive shots, Kurou also managed to widen the already existing gap on Kraken's armor, allowing him to deal the finishing blow to Caligula.

Other: Interestingly, Kurou refers to 3 different things with the same Cthugha name. First, the name of the Great Old One Cthugha. Second, the gun often used for harnessing the entity's powers. Third, the actual attack itself. Not to be confused with its Cthulhu Mythos counterpart.
