So from left to right we have
Ulquiorra Schiffer (Rank: 4th) - Is fairly cold and indifferent to most and one of Aizen's most loyal Espada responsible for kidnapping Orihimie and psychogically trying to break her. Which apparently isn't working too well but he did take out Ichigo. In turn Grimmjow helped revive Ichigo and sent this guy to some parallel dimension where he can annoy others with his emo indifference.
Starrk (Former Nickname: Lazy Bones. Rank: Unknown) - An Espada who likes his sleep. So much so he sleeps through hearing fellow Espada dying. Has an annoying female follower named Lilyenette who appearntly likes beating him up whenever he sleeps which I suspect are quite often.
Nnoitra (Formerly known as Spoonhead, who I now call Espoony Onne Rank: 5th) - Is tall and has a creepy smile made even more creepy by the fact he sounds like Dean Venture hitting puberty. Nnoitra has a Fraccion (an Arrancar chosen by an Espada to follow them) named Tesla and does not like fighting weak opponents wanting to be acknowledged as the strongest even if he already thinks he is. Despite the fact the guy's only ranked 5th. Yeah the guy needs to check that number tattooed on his tounge. Anyway now he's fighting a weakened Ichigo with his incredibley awesome looking sword sycthe thing. Will Ichigo win? Well he should put up a better fight then Chad, the last guy Nnortira ridicolously pwned.
Halibel (Former Nickname: Mrs. Underboob/Censorboob. Rank: Unknown) - The only female Espada who got her nickname due to her arrancar uniform, which as you can see was censored when it hit the anime. Has three female Fraccion followers (Mila Rose, Sun Sun and Apache) and is watching Ichigo and Grimmjow's battle and comments how it's like an Espada battle more then anything. And that's all we know about her.
Aaroniero Arruruerie (DECEASED) (Rank: 9th. Former Nickname: Mr. Bubbles. Arrancar Zanpakto: Glotoneria). Now it can be revealed: Aaronierio is the only Gillian member of the Espada. A two head weirdo who can actually absorb a hollow's abilities and powers when it dies. He actually ate the hollow who ate Kaien which explains why he can take his form. He's also the first Espada to show off his resurrecion which is some sort of giant.. purple tentacle monster with two jaws on either side of his body. He has the power of thousands of hollows and the potential to use all of their powers in his resurrecion form. Ruika killed him by stabbing him in the head. However he played his death to the other Espada and seemingly killed Ruika when she killed him.
Yammy (Rank: 10th) -The first Espada we've met and from what we've seen essistanly dumb and fairly easy to beat. If you're not Orihime or Chad that is.
Old Guy (Nickname Due To Not Being Named Yet. Rank: Unknown) Nothing really know about him besides the fact he's... old. And complains when people die stupidly.
Syazel Aporro Granz(Rank: 8th Former Nickname: NERDDDDDDDDDDDDDDDDDDDD and The Prissy one) - The younger brother of Illford Granz (15th Arrancar and one of Grimmjow's Fraccions killed by Renji 40 episodes ago) Syzael is apparently the scientist of Hueco Mundo and enjoys collecting new expierments to work on, even those of his fallen team-mates and family members. A fairly sick and twisted indivudal but his fact finding made him able to counter all of Renji and Uryu's attack with only his shirt sustaining any true damage. The group has elected to run away from this weirdo, but he found them again in a snazzy new cape and has some new tricks to show them. He also apparently appreciates theatrical drama, as evidence in the above title.
Affirmative Action Arrancar (Nickname Due To Not Being Named Yet. Rank: Unknown) - He's Affirmative action because he's the only true black arrancar/Espada in the anime. Yammy's more mexcian, Underboob's a mulatto and Tosen isn't an arrancar. Shown mediating after Aarenerio's death).
Grimmjow Jagerjaquez - Rank: 6th. (Zanpakuto: Pantera) Ichigo's Espada rival who reclaimed his spot after offing Luppi His rage and rebelling attiduing also makes him one of the more popular Espada. Especially when he smacked around the two ****** who were harassling Orihime, brought the orange haired "princess" to Ichigo so she could heal him, sent Ulqouirra somewhere and fought Ichigo for one last fight and was defeated. Grimmjow released Zanpakto is named Pantera which turns him into some sort of blue kitty kat man who Ichigo defeated, but then saved from being killed by Nnortira. I'm sure we'll see what happens to him after this fight, since considering he's quite popular the author Tite Kubo wouldn't just randomly forget him, right?
