The Cathode is a destructive, aggressive species of Monovision, which acts as a suicide-bomber that charges at foes en-masse. Unlike the somewhat-comparable Knob and the blatant and obvious Blitzer, the Cathode, or "Cathy" as it's also known, tends to be an ambusher, trying actively to flank and sneak up on foes before leaping forwards and detonating in a burst of energy and shrapnel.

Cathys will actively target Trenches and Objectives as opposed to turrets, but they will go for any target of opportunity if one is available. Though they appear in smaller numbers than Knobs, they cause considerably more damage, and the blasts they cause are substantially larger.

They emit a distinctive, high-pitched chirping when they emerge from the Conduit, and prefer to advance under cover from terrain obstacles that mask their presence, such as water or large clusters of Martian Xenoflora.

They appear only in Rise of the Martian Bear.

Tactics for DisposalEdit

Beware these tubes, and prioritize their destruction. Picture them as bigger, nastier, more intelligent Knobs, and you begin to understand why they're dangerous. You can't fall into the trap of thinking "it's just some Cathys," because they can do the kind of damage to a Trench or Objective that Knobs typically do to turrets.

Cathys have very little health and are vulnerable to rapid-fire weapons (such as Machine Guns), weapons with an area-of-effect (such as Artillery Cannons), or both (such as Broadcasters), but they can do extremely heavy damage, seemingly disproportionate to their size. Because they tend to cluster in packs as well, a cluster can cause serious damage even to an assault trench, such as a Kauffson or a McQuarry. Engineer Trenches need to be especially careful, as a Cathy swarm can easily bring one down.


  • Like all Monovision creatures, the Cathode is named for an object or terminology common to radio and television; a Cathode being the core component of a CRT monitor, which the Monovisions tend to incorporate into their bodies.
