Cybertitanium

Cybertitanium is a substance in the Japanese Generation 2 and Robots in Disguise continuities families.

Cybertitanium (セイバーチタニウム, se-i-baa-chi-ta-ni-u-mu) is apparently a very strong kind of metal, possibly from the Transformers' home planet of Cybertron. Firebot's chassis is made out of it, making him practically unbeatable in battle. Meanwhile, Dangar's Cybertitanium caterpillar tank treads enable him to traverse any road, no matter how rough.

Trivia

 * The "cyber" in "Cybertitanium" is written with the katakana used for the Transformers' home planet of Cybertron (セイバー, se-i-baa) rather than the katakana that make up the "cyber" in Cybertron, the Japanese name for the Autobots (サイバ, sa-i-ba). Ergo, the metal likely derives from that world.
 * So far, this metal has only been mentioned on two Japanese tech specs. Obscure!
