Designed to protect him against the rigors of interstellar travel, the Protoform mode of OPTIMUS PRIME is a pitted, meteor-scarred apparatus of alien metal, forged in the heat of distant suns. Its rounded, flaring edges are lined with superconductive materials to bleed away the catastrophic heat of reentry into a planetary atmosphere. Housed within his indestructible body, OPTIMUS PRIME also carries the same scanning equipment as the other TRANSFORMERS, with which he scans an Earth transport vehicle, adopting its shape as his disguise on this new planet. Thus hidden, he is free to move about this planet among its inhabitants keeping them save and secure until the time comes for him to reveal himself.
