During the Fake Karakura Town arc, Ichigo seemingly dies at Ulquiorra's Instantaneous Cero Oscuras after a long battle where Ichigo used up all his Shinigami and Vizard powers and still did not even managed to land a scratch in Ulquiorra. After hearing Orihime's desperate cries, he revives as a new hollow form but unlike his previously seen form. He has long straight hair, reaching down to his waist, and a Hollow hole even larger than his previous one, decorated with markings stretching from the hole, across his chest and shoulders. He also has retractable claws on his fingertips and toes, small furry tufts, two starting from his collarbone and stretching around his neck, and one each on his wrists and ankles, as well as seemingly white skin. In this new form, he has a different Hollow mask that while the face is shaped the same, it covers Ichigo's entire head and its markings are different as it has four spike-shaped marks stretch, two of them stopping by the forehead, and the other two stretching past the eyes and teeth, going past his chin and joining with the marks on his chest. There are also small marks resembling a heart, but with the top and bottom open, extending from the inner corners of his eyes. The mask features two long forward-pointing horns with black strips extending from their center towards the tips. The extent of his powers are still unknown but he managed to quickly overpower Ulquiorra in his second release form, who earlier completely dominated Ichigo while using his Bankai/Hollow Mask combination.
Telekinesis: Quickly after transforming, Ichigo was able to call Zangetsu back to his hands with just the wave of his hand
Enhanced Cero: His Cero has become exceedingly more powerful, capable of countering Ulquiorra's Cero Oscuras and causing large scale destruction to large portion of the surroundings. It is fired from between the tips of his horns instead of his fingers as it was during Ichigo's Vizard training. Hollow Ichigo's Cero is now violet (or purple) in color.
Enhanced Strength: Ichigo's strength is still unknown, but he managed to easily tear off Ulquiorra's left arm without much resistance from the Arrancar's Hierro and easily slashed Ulquiorra from his left shoulder to his lower right hip through his Hierro. He also destroyed a large portion of Las Noches's roof with the wake of a single slash of his sword and barehandedly crushed Ulquiorra's strongest attack, Lanza del Relámpago and forced it to collapse before Ulquiorra even got a chance to throw it.
Enhanced Durability: Ichigo's durability has greatly increased, able to withstand several large explosions in his battle with Ulquiorra at close range with no visible damage. His skin and hands are also strong enough to catch and hold onto Ulquiorra's strongest attack, Lanza del Relámpago, without any damage.
Enhanced Reflexes: Although mostly not seen, Ichigo was able to easily dodge Ulquiorra's Lanza del Relámpago which as aimed at his head at close range. (Note: Ulquiorra did admit he did have trouble controlling it)
Sonído: Ichigo manages to move at exceedingly incredible speeds, quick enough to appear behind Ulquiorra's back and effectively counter him before the former could even turn to face him. Ulquiorra also comments that his speed is not reached by the use of Flash Step; he actually uses Sonído.
Enhanced Spiritual Power: His spiritual power is unknown, but Ichigo's already immense spiritual power increases drastically, as it is easily able to overwhelm Ulquiorra's own second release power. Its sheer strength was great enough to horrify Rukia, Renji, and Yasutora Sado who sensed his spiritual pressure far away from the bottom of Los Noches.
Instant Regeneration: After Ulquiorra shatters his mask the energy from his Hollow transformation went above him and came down as some sort of energy that regrew the lost flesh that made his hollow hole and even fully rejuvenated him of his injuries from Ulquirorra, to who commented on it to that effect.
