The Three-Star Dragon! The Final Battle Begins!!

Summary
Cooler looks behind and notices the Three-Star Dark Dragon standing behind him and introduces himself as Nether Dark Shenron and demonstrates that he use Ice attacks and Nether attacks. He knocks out Cooler with a single kick before entering his True Form and proceeds to knock the Saiyans away as he unleashes his ki.

Using a mix of Super Ice Ray and Ice Ray; he freezes the Saiyans in place as Cooler powers back up to his Super Metal Form and Dial arrives; placing him into a bear hug and flies Nether into a cliff. Dial enters his Super Emerald Form but both him and Cooler are easily overpowered by Nether and are severely beaten before Dial enters his Ultimate Divine Sorcerer Evolution form and overpowers the Shadow Dragon with ease.

Dial powers up to his God of Sorcery and Horror form and proceeds to fight alongside Cooler against Nether. Nether attempts to stop Dial with his Dark Lord Flash but it has no effect and attempts to take him down with Dark Ice Flash and Dark Lord Ice Orb, but again no effect. Nether places Cooler in a Full-Nelson and attempts get him to surrender, but he remains resilient.

He unleashes his ki and attempts to force Nether to let go but fails as Dial kicks the Shadow Dragon in the head forcing him to let go. Nether punches Dial in the gut before kicking Cooler in the chin and flying onto a piece of debris caused by Obrensaika's self-destruction and proceeds to transform into his Super form.

Dial attempts to use his magic to attack him but Nether alters the attack into a harmless energy wave before causing a massive earthquake beneath them and exposes an underground volcano beneath the deserts before causing it to erupt. The two avoid the eruption and uses ki blasts to destroy the volcano before using Necromancy to reanimate the corpses of nearby animals and Earthlings before granting them ki and flight as they attempt to attack the two aliens.

However, they easily destroy the reanimated bodies with a few kicks. Dial enters his Ultimate Sorcerer God Evolution - Fear Accelerated form and proceeds to attack him but Nether is able to dodge the attack as Cooler is knocked down by a punch. Cooler uses his rocket launcher to fire a barrage of ki-based missiles, but Nether easily freezes them before bifurcating Cooler.

Dial proceeds to relentlessly attack the Shadow Dragon while Nether simply takes the beating before grabbing Dial's tail and hurls him into the ground. Dial attempts to transform once again but Nether knocks him down and sends him flying into a mountain. He is able to use Rebirth to survive the attack and proceeds to power up even further and uses every ounce of his energy to begin a nightmare transformation and enters his Nightmare Metal form.

Cooler and Nether proceeds to charge at one another.
