The Median is the elite variant of the Nexus boss.
As with all elite variants, the Median is much tougher, slightly faster and packs add-ons to its original abilities compared to its lesser counterpart. Unlike several of the other bosses, the Median does not gain any distinctly new abilities, but its rearward laser can now improve the damage of controlled enemies as well as their mobility. This enemy's weaponry has the same appearance as the "Repeller" and "Whirlwind" autocannons.
