Airachnid

Airachnid is one of the villains in the TV show Transformers Prime. She was a former Decepticon who left and desided to hunt endangered specises for the trill of Hunting. She originally took the form of a half spider creature, but recently in order for her to escape she took the form of a helicopter.

Before Transformers Prime
During the war on Cybertron, Airachnid captured both Arcee and her partner; Tailgate. Airachnid demanded Arvee tell her where the attack coordinates were, but Arcee said that she didn't know. Believing she was lying, Airachnid threaten that she would kill Tailgate if she tell the coordinates. Since Arcee didn't know the coordinates, Airachnid killed Tailgate. She was about to kill Arcee as well until, Bumblebee, and Cliffjumper rescued her. Airachnid retreated and disappeared.

Transformers Prime
When Arcee and Jack were investigating they encountered Airacnid. She entrapped Arcee again and this time attempts to capture Jack nd place him on her trophy. That night Jack encountered Airachnid's ship and attempted to blow the ship up along with Airachnid. After her ship was destroyed she retreated underground.

When Airachnid was surrounded by the terroist group; M.E.C.H., she made a deal with them, that if they help her capture both Jack and Arcee, she would let them use Arcee so they can learn about the Transformers. Doing so they captured Jack's mother and force Jack and Arcee to meet at a warehouse. Airachnid struck a deal with Jack that if Jack and rescue his mother before midnight she would release both of them (not promising Arcee will be release). Jack manage to call Agent William Fowler while searching for his mother. When Arcee broke free from Airachnid's web and got away from M.E.C.H., she rescued both Jack and his mother, while fighting Airachnid. When Fowler came with a small army, Airachnid took the form of a helicopter and retreated, again.
