Reformed from her Predacon history of treachery and double-dealing, Blackarachnia became a Maximal largely thanks to her relationship with the noble Maximal known as Silverbolt. Under the command of Optimus Primal, Blackarachnia proved herself in the battles to liberate Cybertron from Megatron's tyranny. Following the Maximal victory and reformatting of Cybertron itself, Blackarachnia enjoyed a brief spell of peace and happiness with Silverbolt by her side. However, due to the machinations of Unicron, Blackarachnia has once again been corrupted, this time siding with a renegade Decepticon faction loyal to Unicron.
