The Titans Sword (Perfect Effect)
The The Titan's Sword is a third-party Transformer accessory made by Perfect Effect, intended for the Titans Return Fortress Maximus figure. It was released in June of 2016. The set can work as a sword for Cerebros, or combine into one large sword for Fortress Maximus.
While the top half of the Blade can be combined with a smaller hilt appropriate for Cerebros, the sword itself is much to large to be functional.
The Titan's Sword is matched with PC-14, the The Titan's Cannon.
