It was a dark and stormy night, with fierce thunder and lightning lighting up the skies. Indra Ōtsutsuki appeared in a flash of light, his eyes gleaming red as he scanned the area. He had come for a battle, and nothing was going to stop him. Suddenly, he heard rustling in the bushes, and out came Sukuna. "Hmph," said Indra, "I expected a tougher opponent." "You underestimate me," replied Sukuna with a smirk. Indra summoned his complete body Susanoo, his exoskeleton of chakra covered him from head to toe, with ornate armor and a sword. Sukuna immediately created his domain, Malevolent Shrine, with his guaranteed-hit ability. Sukuna charged towards Indra with immense speed, ready to slash him apart with his cleave attack. But Indra had the Sharingan, and he was able to predict Sukuna's movements with great accuracy and paralyze him with a single gaze. Sukuna was caught off guard, and his attack missed. Indra then summoned Hinokagutsuchi, causing black flames to erupt at the focal point of his vision. Sukuna tried to cut through the flames with Dismantle, but the flames simply regenerated themselves. Indra then used Amaterasu, creating black flames that burned hot enough to incinerate Sukuna. However, Sukuna's domain was still active and Indra was unable to completely vanquish him. Sukuna regenerated and launched himself towards Indra with an arrow of fire, slicing through Indra's Susanoo ribs. Indra countered with his Mangekyō, copying Sukuna's space-time control ability and transporting them both to a different location. The two fighters clashed in a fierce battle, each one trying to gain the upper hand. Sukuna's spiderweb cleave attack adjusted itself to the surroundings, making it impossible to dodge. Indra summoned his Susanoo ribs as a shield, but Sukuna's attacks kept breaking through. Finally, Indra saw an opportunity and used his lightning control ability to strike Sukuna with lightning bolts. Sukuna's domain amplified his curse energy, allowing him to regenerate from the attack almost instantly. However, his curse energy was unable to completely heal his injuries, and he was left weakened. Indra, seeing his chance, struck Sukuna with his sword and delivered the final blow. Sukuna was defeated, and Indra emerged victorious. Winner: Indra Ōtsutsuki Indra's Sharingan was able to predict Sukuna's movements with great accuracy, and his Amaterasu was able to incinerate Sukuna's attacks. Despite Sukuna's powerful curse energy and domain, Indra's lightning control ultimately proved to be more effective in delivering the final blow.
