Crescens is a thin white and gold Gear with no arms and large green angel wings on its head. The Gear was constructed by Solaris to be used exclusively by Emeralda. Similar to its pilot, it is made at least partially out of nanomachines. The Gear makes its first appearance at the Sargasso Gate when Krelian, having harvested enough of Emeralda's nanomachines to suit his purposes, turned her loose on Fei and his friends in the hopes that they would dispose of her for them or vice-versa. After Crescens was defeated the brainwashing performed on Emeralda wore off and she then joined Fei's party in their quest to stop Krelian. Perhaps as an Easter egg for fans of Xenogears, Crescens gears are enemies in the Omega System dungeon in Xenosaga Episode II. One of the more prominently features mecha in the game, Pellegri's E.S. Issaachar also wields a powerful weapon called the "Crescens' Claw". In battle Crescens, is one of the fastest Gears with high accuracy, but like Elly's Vierge this is offset by poor framework.
