Guardian

The Guardian (ガーディアン) is a Heartless boss which appears in Twilight Town in Kingdom Hearts 358/2 Days. It resembles a giant black Surveillance Robot. When fought, it is aided by multiple Surveillance Robots. It has one attack, where it shoots a laser in a circle around itself. This is easily avoided, as long as you do not get in front or behind it. Axel fights alongside Roxas in this battle. Guardian is fought on Day 22.

Kingdom Hearts 358/2 Days
These large flying drone Heartless fire a super laser that damages anything in its path, friend or foe. ''Regular attacks will not stagger the Guardian. To disable its super laser, jolt it with Thunder.''

TIP: Nil-based attacks like the super laser can null your defense, increasing the damage you take.
