Stilicon

Stilicon is a fictional material appearing in the Marvel Comics universe, primarily associated with the villainous character Doctor Doom. Its exact composition and properties are often left somewhat ambiguous, but it is consistently depicted as an extremely durable and resistant substance. Doctor Doom frequently employs stilicon in the construction of his armor, weapons, and fortresses, leveraging its resilience against various forms of attack, including extreme temperatures and energy blasts. The material is understood to be a product of Doctor Doom's advanced technological and alchemical genius, making it a rare and valuable commodity, obtainable only through his efforts. While not as widely known as vibranium or adamantium, stilicon serves as a significant element in the technological arsenal of one of Marvel's most formidable antagonists. Its presence reinforces Doctor Doom's status as a master inventor and a threat that few heroes can easily overcome. The resistance offered by stilicon has been a key factor in many confrontations between Doctor Doom and the Fantastic Four, as well as other Marvel heroes.
