Superboss (XC1)

The superbosses of Xenoblade Chronicles are a group of five optional enemies that are significantly difficult to defeat, and thus form the game's greatest challenge. They have all the following in common:
 * They are s.
 * They are above 99, so the player cannot match them.
 * They drop the Veritas Glyph, the most expensive material in the game.

Four of the five superbosses also:
 * Only appear after the events of Mechonis Core.
 * Have unique arts that are shared by no other enemy.

List of superbosses

 * Final Marcus is a level 100 Slobos at Three Sage Summit. He does not meet the secondary superboss criteria of "only after Mechonis Core" and "has unique arts", which combined which his level (low enough that the player can fight him without a red tag), invites discussion over whether he is a "true" superboss.
 * Ancient Daedala is a level 105 Mechon at Wreckage Beach. It is known for its ridiculous sight range and punishing range spike.
 * Despotic Arsene is a level 108 Bunnia at the Glowing Obelisk. He has the highest agility of the superbosses (when level difference is accounted for) and resists practically all debuffs.
 * is a level 114 Behemoth at Great Glacier. He has very wide-ranging and heavy-hitting arts with long cooldowns, some of which gain extra effects if a blizzard is ongoing.
 * is a level 120 Dragon at Three Sage Summit. He has an counter spike and only appears during night blizzards.
