[up & down arrow keys to transform] Long ago, a young Embersteel was given a mission by Primus himself: to hunt down & destroy the Legendary Heralds of Unicron. To that end, Primus forged a new Matrix: The Matrix of Honor, & bestowed it upon Embersteel, transforming him into Embersteel Prime. Decades later, Embersteel Prime and his Crew were hunting down one such Herald, when they crashed on earth. Awakening amid the industrial revolution, Embersteel's crew scanned various locomotives in order to hide themselves from local life forms. Embersteel himself scanned a freelance design 4-4-0 tender engine built for light passenger work, giving him ample opportunity to observe human customs, & Embersteel Prime would come to be very protective of these delicate organic life forms, Which made him all the more worried when he felt it: the Matrix of Honor, pulsing and whirring within his frame, something it had only done when a Herald of Unicron was approaching. Something was coming, something that could spell disaster for the human race, and Embersteel Prime & his crew would have to risk revealing themselves in order to save them. Bio: Embersteel Prime is a strong but compassionate leader who cares very much for his crew, always putting the needs of others before his own. This will sometimes conflict with his mission, & he struggles to find a balance between protecting his team, and hunting down the Heralds of Unicron he was so long ago tasked with defeating. His weapon is a thermal cannon. Allegiance: Autobot.
