What episode in bleach does ulquiorra cifer get introduced?

Answer 1

Ulquiorra supposedly dies by fillers in episode 136, yet appears later in the episode. The episode date when he actually dies is unkonwn, but can be found in the manga.

He dies in episode 272.

He kills Ichigo, by releasing his zanpakuto, and greatly overpowering him, becoming strong enough to resist the Lunar Fang, then after beating Ichigo up uses what I call a, *bankai* but is really called resurection, segund etapa. He is the only of the arrancars with a second release, or bankai, which Lord Isan hasn't seen him in the form. Here, he beats Ichigo up again, and then Orihime and Uryu show up. Ulquirra kills Ichigo with Cero Oscurus while he is held by Ulquiorra's tail, then tosses him of the cliff where he is, then Orihime uses a moving shield to catch him. She runs, and Ulquiorra blocks here from reaching him. However, Uyru assaults him, using an arrow that stuns Ulquiorra, allowing Orihime to go to Ichigo to heal him (fails to). Uryu continues to fight him, with a small advantage of allowing himself to stay away from Ulquiorra, firing a massive amount of arrows and using Sonido each shot. However, Ulquiorra uses a charge similer to the one he used when he started fighting Ichigo, and knocks Uyru into one of the pillers. As Uyru tries a new trick, Ulquirra grabs his wrist and breaks it. Orihime see Uyru and tries to protect him, fails. Somehow, Ichigo becomes a full hollow with a zanpakuto (still Zangetsu) due to the hole Ulquiorra made with his cero. Ichigo's cero matched his, and then overpowers him. He wins, and finishes him off poorly, due to Ulquiorra's resistance. Then the hallow decides to stay him in the throat, but Uyru stops him by grabbing his wrist. He isn't strong enough to hold him back, but Uyru starts yelling, and Ichigo charges a cero on Uyru. Orihime starts yelling, and aims it between them both, thinking she is going to betray him too. Ulquiorra then saves the 2 but cutting off part of his mask (a horn like part of it) and the cero discharges on Ichigo, and blasts off Ulquiorra's Wing, arm, and leg, and burns part of his tail. Ichigo then gains instant regeneration for the hole, and becomes normal again (with added regeneration, along with his vizord abilities). Then Ulquiorra challanges Ichigo, however, Ichigo asks for the same damage he has to make it fair. However, he begins fading into dust before he can. Ulquiorra asks Ichigo to finish him off as he always wanted to, but Ichigo declines. So Ulquiorra then dies, understanding Orihime.

Rumar: Ulquiorra used a method to slowly turn to dust, looking as if he is dieing, and when touched or attacked will speed the process, and is actually still alive.
