Fiction

Prime cartoon

When Bumblebee used a Cortical psychic patch to enter into Megatron's mind, he faced the Decepticon warlord himself. As Megatron attempted to destroy Bumblebee, he discovered that his physical attacks simply passed through the Autobot's body. This led to Megatron determining that his foe was not wearing Phase displacement armor, was not using holograms as his eyes tracked his movements and Megatron himself did not believe in spirits. Thus, he concluded that Bumblebee had intruded into his very mind by way of a cortical psychic patch. Sick Mind
