Shamshel

Shamshel is a roughly Evangelion-sized insect-like Angel capable of transforming between a horizontally oriented "flight form" and a vertically oriented "combat mode". Its offensive weapons are two long, glowing, pink energy-tentacles. The tentacles, which are strong enough to lift an Evangelion off the ground and throw it a large distance, also have power to pierce an Evangelion's torso with little effort. Its skin is mostly purple, with some pink sections underneath its "head". Shamshel appears to have two false eye spots on the top of its head composed of an inner black circle and outer yellow ring.
Shamshel has two main arms, from which its long energy-tentacles extend. The Angel's core is located on its torso just underneath its head. It also has eight small, insect-like legs situated underneath its "head", situated just below its core. The energy whips are actually physically structures; they're not just made of energy, though they are charged with energy, as can be seen when they power-down after Shamshel dies but are still physically present.
When Shamshel switches from its flight-form to its battle-form, its large front arms (which the energy-tentacles come out of) change form as well. They don't just separate and change position (when in flight-form they are touching each other), but actually change shape somewhat.
Shamshel appears more aggressive than the preceding Angel, Sachiel. While Sachiel took largely to a defensive standpoint after the damaged Eva-01 went berserk and attacked it, Shamshel was much more aggressive in attacking Eva-01, severing the umbilical cable and flinging the Eva all the way onto a mountainside before moving to attack it again.
