Vahkshi (GokaiWhite)

The Vahkshi (ヴァックシ Vakkushi) are powerful creatures which are said to be linked to the cause of Ankoku Nui's decaying state. They are actually mass-produced sentient machines built by Scryptorek to help him run the Mako Reactors and eliminate trespassers.

Powers and Abilities
The Vahkshi come in eight colors and elemental properties, and each one is stronger than an average Vahki and Rahkshi each put together. Over time, they begin to adapt to the heroes' tactics and learn how to invert the colors in accordance to this chart below, much like a chameleon blending in with it's environment. They are also supposed to gain the ability to sprout wings and fly.

Trivia

 * The Vahkshi "existed", before Bionic Fantasy was conceived, as hypothetical/fan-made MOC's built from pieces used for Rahkshi and Vahki, hence their name being a combination of Vahki and Rahkshi. The default set made by GokaiWhite is white and black, as an example their elemental inverse ability.
 * They are supposed to have been inspired by the Mass Production Evangelion series, as GokaiWhite once stated that the Rahkshi (in 2003 movie form), especially Kurahk, remind him of the MP Eva's.
 * Also the color scheme for the purple Vahkshi with neon green accents is an homage to Evangelion Unit-01, the "flagship" mecha of Neon Genesis Evangelion.
