Sideways

Sideways was a Herald of Unicron who conspired with the Fallen to resurrect Unicron.

History
In 150,080 CMT, Sideways was tasked with capturing Starscream's antidermis, the final component that the Heralds needed to revive Unicron. The Fallen teleported him into the wreckage of the old Darkmount, which was where Starscream was wandering around. Sideways agreed with Starscream's assessment that it was lucky he appeared there through a plothole, because now he could extract his "immortal soul". Sideways immediately blasted the Makuta with Nox energy and trapped his antidermis inside a container. Sideways then radioed the Fallen for extraction and was teleported back to the Fallen's home dimension, which is where they began the ritual to resurrect Unicron.

Later, the Fallen summoned Sideways and six other Heralds of Unicron (Blackarachnia, Galvatron, Obsidian, Razorclaw, Strika, and Xaaron) to help him kill Zev Raregroove and his friends, because they were attempting to prevent Unicron from consuming BZPower. Sideways followed his allies into the seventh dimension, who began travelling through it to Zev's location, but they were intercepted by Tokimi along the way. In order to protect her friends, Tokimi used her powers of entropic balancing to destroy all eight of them. The Fallen, however, came back somehow... but he always comes back.
