Grafitoid

Grafitoid is a fictional material featured in the science fiction franchise Transformers. It is a dense, exceptionally durable, and non-metallic substance that serves as a vital component in the construction of advanced Cybertronian technology. Its primary characteristic is its extreme resilience, making it resistant to conventional weaponry, extreme temperatures, and radiation. This durability is crucial for the survival of Cybertronians in harsh environments and during intense combat.

In the lore, grafitoid is often described as being mined from asteroids or found in specific geological formations on Cybertron. Its unique properties allow it to absorb and dissipate energy, further enhancing the defensive capabilities of vehicles, armor, and weaponry. Transformers often utilize grafitoid in their internal structures and external plating to withstand the rigors of battle. The material's non-metallic nature also contributes to its resistance to certain forms of energy-based attacks that might affect metallic components. The rarity and difficult extraction process of grafitoid are sometimes plot points, highlighting its strategic importance to both Autobots and Decepticons. Its presence in a Transformer's design often signifies a high level of technological advancement and combat readiness.
