The Fullerene Endochassis was designed somewhere between the years 3146 and 3151, primarily for use by the Spirit Cats and Steel Wolves in their conflict against the Society. Composed primarily out of Fullerenes as the name implies, this Endochassis is produced in "generations", each new generation superior to the last in some aspect. The unusual properties of certain carbon allotropes mean that in addition to being lighter and stronger, the new chassis improve a mech's effective heat dissipation by around 20% (rounding down).
