Tridente

Tridente (Jap. トライデント lit. Toraidento), a new faction under Aizen's control, they are a race similar to the arrancars, but they differ by being capable of going to shikai and bankai aside from ressureccion. The only known Tridente till now is Arquímedis Sosuke.

Currently their master is Aizen Sosuke.

Overview
In appearance, they differ than normal arrancars by having more than one hollow hole, depending on their rank (e.g. Kappa Tridente has 10 holes, Iota Tridente has 9 holes, etc...).

Upon becoming a Tridente, they would attain another zanpakuto upon transformation which is the one capable of going to shikai and bankai.

The process of transformation is still unknown.

Their rank (greek alphabet) is tattooed on them in different position upon transformation.

Unlike the arrancar, the remaining hollow fragments of Tridente disappear

Tridente don’t have fraccions.

What’s new about the Tridente is that they have different names but share the same last name, they are not related, but just to show their loyalty to their master.

Each Tridente other than his name has a title, describing his characterstic.

The Tridenete uniform consists of black hakama and white kosode, with a cape which differ from Tirdente to another, and in addition to a belt of the same color of the cape.

there are 10 Tridente, however only Kappa Tridente has been shown so far.

All Tridente’s zanpakutos (both) have black hilts, and black sheaths.
