The Guardian is the first boss you'll encounter in Connected Mode, serving as an introduction to cooperative boss battles. It's relatively straightforward but teaches essential team mechanics.

Phases & Attacks
- Phase 1 (Initial): The Guardian will periodically send small amounts of garbage lines to each player's field. These are usually 1-2 lines at a time.
- Phase 2 (Enraged): After taking some damage, the Guardian's attacks become more frequent and slightly larger, sending 2-3 lines of garbage.
- Zone Attack: When the boss is vulnerable (indicated by a glowing core), activating your team's combined Zone will deal significant damage.
Strategy & Weaknesses
- Clear Lines Consistently: The primary goal is to clear lines to fill the team's shared Zone meter. Focus on efficient line clears, especially Tetrises, to build meter quickly.
- Coordinate Zone Activation: Communicate with your teammates (even if just through pings or emotes) to activate Zone when the boss is vulnerable. Activating Zone when the boss is not vulnerable will still clear lines but won't deal bonus damage.
- Support Teammates: If a teammate's field is getting high, try to clear lines quickly to send garbage to the boss, which can sometimes alleviate pressure on your team. During Zone, focus on clearing as many lines as possible in the merged field to maximize damage.
- Weakness: Consistent line clears and coordinated Zone attacks.
