WX-78 is the fourth playable Character unlockable via Experience, with 960 XP. It is a self-sustaining automaton that hates all living matter.
WX-78's Health, Hunger, and Sanity are all set to a maximum of 100 points, but it's able to eat Gears to upgrade these stats to 400, 200, and 300, respectively. Being a machine, it takes damage when it is in the Rain unprotected. When struck by Lightning, WX-78 will experience "SYSTEM OVERLOAD", emitting Light while moving at an increased speed. WX-78 can also eat stale and spoiled Food without the negative effects. Overall, WX-78 is a very good character with great bonuses and very small drawbacks.
WX-78 will lose 33 and gain 100 when initially struck by Lightning, and can be struck multiple times after System Overload has been activated. System Overload lasts for roughly 1 Day but can be stacked from multiple strikes to last indefinitely. Being near a Lightning Rod will prevent WX-78 from being struck. It should be noted that it is possible to set nearby objects and Mobs on Fire when struck by Lightning.
WX-78 also has the ability to permanently upgrade its maximum Health, Hunger, and Sanity. This is done by "eating" Gears. A total of 15 Gears must be eaten to gain maximum stats. Each upgrade adds 20 , 6.66 , and 13.33 (shown in the table below).
WX-78 is also able to eat stale and spoiled Food without penalties. This allows it to stockpile Food for increased lengths of time. Note that other Food penalties still take effect (such as eating Monster Meat).
Disadvantages
WX-78 has the lowest starting maximum stats of any Character, leaving it exposed to danger until Gears are found.
WX-78 takes damage from Rain, at a rate of 0.5 every 3–5 seconds (the amount of Rain does not matter). This damage causes WX-78 to periodically emit Light as sparks fly off its body. The light emitted is enough to prevent Charlie from attacking, but at the cost of big amounts of Sanity.

In the Reign of Giants (RoG) and Shipwrecked (SW) DLCs, the addition of the Wetness mechanic changes the way WX-78 is damaged by Rain. When completely exposed to Rain, WX-78 will take a maximum damage of 0.5 every 3–5 seconds. Water resistant equipment will reduce this damage. For example, damage will be reduced by 50% while wearing 50% water resistant equipment (i.e. a Pretty Parasol), taking only 0.25 damage every 3–5 seconds. WX-78 will also take damage from Wetness after it has stopped raining, at a rate of 0.3 every 3–5 seconds. This is "drying" damage as the Wetness meter empties. Standing next to a Fire will significantly speed up the rate at which the Wetness meter decreases, potentially becoming dry (after being soaked) in a matter of seconds.
In Shipwrecked, WX-78 is immune to Poison and can take damage from the Wetness gained by walking in Puddles and the Tide.
Tips
SYSTEM OVERLOAD will also be initiated from lightning strikes after the following occasions:
Equipping an Umbrella will completely block the Rain, preventing any damage from being taken. Since the Umbrella does not degrade over time in the normal version of the game, it makes this drawback a non-issue.
In DLCs the Umbrella only lasts for six days rather than 20 hits. It also won't stop the Rain completely on its own. An Eyebrella, Rain Coat, Dumbrella, or Blubber Suit are generally preferred.
WX-78 players may want to use the Umbrella or Blubber Suit over the alternatives during spring storms and hurricanes since they offer no lightning immunity, thus WX-78 can still get a SYSTEM OVERLOAD while using them.
Using the Ice Cube or Fashion Melon as protection from Overheating in RoG or SW is not advised, as the Wetness gained from those items will damage WX-78.
WX-78 can still benefit from consuming Gears even after reaching the maximum upgrade. Each Gear restores 60 , 75 , and 50 .
RoG includes many new Chess biomes scattered around the world in Sandbox Mode (which may have Clockwork Monsters), making it easier to acquire Gears without having to go underground or to a new world. Also, Tumbleweeds have a 1% chance to drop Gears.
During a Spring start in RoG, the abundance of Butterflies can help offset the damage taken from Rain (by eating Butterfly Wings).
When it's raining in DLCs, unless planning to dry soon, it's not advised to wear gear that provides 100% water resistance when highly wet as usually the "drying" damage is higher than the damage taken with a lower water resistance (e.g. Straw Hat + Pretty Parasol).
Due to its high maximum Hunger and ability to eat spoiled food without penalty, Meaty Stew is exceptionally useful for WX-78.
Since WX-78 can eat spoiled food without penalty, food that takes longer to spoil when cooked should be cooked relatively early in its lifetime to increase its lifespan.
Trivia
WX-78's name may be a reference to the RX-78 series of mobile suits in the Universal Century gundam series. The most notable being the RX-78-2, the main mobile suit of the original gundam series.
WX-78's voice is played by what is explained as a "crazy processed synth".
WX-78 has a skull in the game files. Also when struck by Lightning in DLCs its skeleton can be seen, suggesting that WX-78 may actually be a human who is encased within a mechanical suit.
It's worth noting, however, that the x-ray effect of electrocution in the game is mostly a cartoon gag - most characters show skeletal features that are obviously not anatomically correct, such as bones in the characters' hair or clothing.
WX-78 seems to identify as a male since he calls versions of himself on the Nightmare Throne a "BROTHER".
This is further supported by the presence of a fake mustache in his "Guest of Honor" Skin in DST.
WX-78 makes a faint 'keek' noise as it walks.
Although it takes damage from Wetness, WX-78 can eat watery foods such as Pomegranates, Meaty Stew, or even Watermelons without being harmed.
WX-78 has other technical components besides its Empathy Module, such as a Chemical Engine acting as a stomach, Optical Sensors acting as its eyes, a CPU functioning as its brain, and a Processing Unit described as being its head. When it sleeps, it activates Sleep Mode.
WX-78 announcing that an ice box is full. Notice that it is not in its normal full caps speech.
All of WX-78's quotes are in FULL CASE, with some exceptions that include but are not limited to "It's full.", "I can't do that." and "Nice and comfy.", which are all in lower case.
WX-78 is described as "hating all living matter"; however, it shows empathy for machines, saying "OH NO. WHAT HAVE I DONE TO YOU?" when examining gears. It also has a soft spot for Bees and Lureplants, stating "A MINDLESS DRONE. I LIKE HIM." and "AWW, IT IS JUST AS EVIL AS I AM.", respectively.
WX-78 is oddly inconsistent with its punctuation in quotes. There are also inconsistencies in WX-78's references; when it examines a Slurper WX-78 will say "IT VIOLATED MY SMELLING MODULE" but when it examines a Durian, it will say "GOOD THING I LACK A NOSE". This may be intentional or just an error.
WX-78 is one of the original four Characters that were available during the closed Beta of DST.
In DST, if the player communicates to others with the Y or U keys as WX-78, all messages will be sent in uppercase letters like its original dialogue.
Bugs
If WX-78 is immediately struck by Lightning after death, it will appear to be resurrected and the game will crash.
When playing in a Shipwrecked world with Lightning set to "Lots" in the World menu, WX-78 can be struck by Lightning while Wally talks, resulting in a bug where the HUD is unavailable and the camera is fixed.

Also WX-78 will lose its upgrade level and drop some Gears on Death. Amount of dropped Gears is a random number between 1/3rd and 1/2nd of upgrade level (a number of eaten Gears, but not more than 15). This means that most of the Gears used for upgrades will be permanently lost.
