Long ago, Airachnid was with the Decepticons, where her cruel, cold-sparked, murderous demeanor served her well. But after the Great Exodus of Cybertron, she decided to go solo. Nevertheless, she still feels a sort of kinship with her former allies, so if a group of humans attempted to disassemble a Decepticon, she would take offense to it.
These days, Airachnid spends her time engaging in her new hobby: collecting endangered species. Well, parts of endangered species. Mostly the heads.
