Fiction

War for Cybertron

When Optimus Prime took Ironhide and Warpath with him to remove the Dark Energon threatening to contaminate Cybertron's core, they saw a space slug moving through the tunnels. Though Ironhide and Warpath were quite startled by their appearance, the newly appointed Prime reassured them that they only intended to destroy the Dark Energon crystals threatening the core. Another close encounter came when a space slug burrowed through some crystals blocking the three Autobots. Ironhide tried the universal greeting, but the slug simply ignored them and continued with its task. Finally, the three Autobots encountered three slugs with turrets on their backs, wanting the Autobots to take control of the turrets. The slugs took the Autobots through Cybertron's tunnels, plowing through the Decepticon army Megatron had left to control the core. The three slugs were lost when a corrupted slug destroyed the floor they were on, sending the slugs and Autobots to the ground below. Transformers: War for Cybertron
