Airachnid

Airachnid is a scientist in only the loosest sense of the word—ruthless, amoral, and more interested in using her discoveries for her personal gain instead of any kind of greater good. Whether it's mnemosurgery, exotic body modifications, or even arcane super-science, Airachnid tackles problems with a mixture of cold logic and a gleeful disregard for ethics.

This attitude would make her an excellent potential Decepticon—and when push comes to shove, she'll readily fall in with their ranks to save her own skin—but given the choice she'd much rather work behind the scenes for warlords, dictators, and other unsavory sorts, cooking up gadgets and pulling strings in exchange for a free workspace, the freedom to experiment as she pleases... and a steady supply of new test subjects to victimize.

She transforms into a stealth helicopter and a giant spider.

She uses a triple-bladed sword and two "electro-stingers".
