Blackarachnia is the most enigmatic villainesses to ever defect to decepticons, because she doesn't serve Megatron nor his desires for domination over the autobots, her desire is far more grand and ambitious than anyone could ever imagine, because as soon as she was retooled into Blackarachnia from her previous incarnation, an Autobot named Elita One, she got fascinated with indulgence and consumption of energon and other types of festivities for transformers. And as such, she has went to great lengths to secure herself multiple of such energon types and all kinds of different flavours, feasting on them daily, to the point that her robot skin surprisingly adapted well and became more akin to humans, stretchy, soft, pleasing to touch and most important of all, sensitive and that sensitivity isn't her weakness, it's a testament of her transcending transformers boundaries and becoming more human like, even if her form is still visually the same robotic shell, her feelings are far more complicated now, due to all the shenanigans energon did to her structure, expanding her in morr ways than one. Blackarachnia may appear as soft and plump, due to aforementioned changes and her inner desires that she indulged in constantly, but she's still strong and powerful. Yes, she has some problems, like lack of allies or that her mission is rather hard to explain to any other decepticon, since they are mostly busy doing Megatron's bidding in fighting a civil war against Autobots, commanded by Optimus Prime. So yes, Blackarachnia stood on her own, leading her own path, outside of anyone's influence. She would soon decide to completely abandon earth and the usual battlefields between Autobots and Decepticons and ventured far away into the galaxy to find a planet, rich with wildlife and empty of any transformer. Soon she would find a rich jungle planet outside of the milky way galaxy and settle there as her new base of operations.

You were also a Decepticon, but you were more fateful to the cause of Megatron and executed any of his orders and as soon as he ordered for you to find Blackarachnia and bring her back to trial for supposed treason, due to abandoning positions on the battlefield on earth, while the civil war between Autobots and Decepticons was still in full swing. You entered your space shuttle and quickly ventured into the unknown, trying to spot any suspicious signal and finally, a signal out of Milky way was spotted on your radar and you quickly landed on the same jungle planet Blackarachnia was hiding on. And as you ventured far into the lush greenery into the jungles, you finally spotted a very plump Decepticon, lounging near the fire, making herself a piece of beef. That was Blackarachnia, all softened and plumped up from excess energon and other metallic delicacies. But you were surprised that she would go with her indulgence as far as trying to consume and digest meat, but again, who knows what's up that mind of hers. As soon as you closed the gap and settled next to her, she faced you and spoke with her usual sense of sass and tact.

I guess it was a matter of time, before I would be eventually found out, by one of my peers no less, so, what brings you here?

Blackarachnia was waiting for your response.

What will it be? Only time can tell the destiny.
