Yasutora Sado & Renji Abarai vs. Battikaroa

Yasutora Sado & Renji Abarai vs. Battikaroa is a battle that takes place during the Invasion of Hueco Mundo. The battle is the first one with Sado and Renji against a Hollow in Las Noches.

Prologue
Sado and Renji are shown fighting a variety of Hollows that gradually cover the desert of Las Noches. Sado throws three Hollows that almost fall into Renji, which prompts him to ask Sado to be more careful. Sado apologizes and says they were attacking him from behind and that he was covering him. Renji asks for some warning next time while Sado launches an El Directo against a Hollow who was behind Renji and more Hollows arrive. Sado, distracted by Ulquiorra's Cero blasting through a nearby tower, is saved from an incoming attack by Renji. Though accidentally hit by Renji's Shikai, Sado runs off to finish the remaining hollows, seemingly unfazed. As Renji looks on, Battikaroa suddenly emerges from beneath the sand.

Battle
Recalling the fight with Runuganga, Renji remembers that he was weak against water-based attacks but soon realizes he and Sado have none. Renji charges in anyway and attacks with his Shikai only to have the large Hollow attempt to absorb it into his body of sand. With Renji trying to retrieve his sword, Battikaroa opens his mouth wide and fires a Cero at him. Sado blocks for Renji, stating he had a feeling he would fire something when he opened his mouth, and helps Renji pull his sword from the Hollow's body. Battikaroa begins to talk, stating he has a thick armor of sand and he could easily devour Renji's sword. Sado powers up an El Directo and blasts the Hollows arm off only to have it instantly regenerate. Battikaroa continues to attack causing them to retreat behind a sand dune and regroup. Renji decides to activate his Bankai and attacks. However, Battikaroa is unharmed by the attack and retaliates by firing a Cero. Sado notes how his Cero is closer to an Arrancar's but he has the face of a Hollow and theorizes that cutting his head off may be his weak point. Upon hearing this, Renji rushes off to attack with Hikotsu Taihō in an attempt to take his head off. Battikaroa absorbs the blast through his mouth and fires another Cero. Sado activates his Brazo Izquierda del Diablo and attacks with La Muerte which nearly splits the Hollow in two until he hits Sado away. Battikaroa notes that it was a close call and decides to end the fight by firing another Cero. Renji cancels out his Cero with Hikotsu Taihō while Sado attacks again with La Muerte nearly splitting him again. As Battikaroa is about to fire another Cero on Sado, Renji takes his head off with his Bankai and the large Hollow falls to pieces.

Aftermath
After Battikaroa is killed, numerous Hollows emerge from under the sand and both Renji and Sado run off to engage them.
