The Characters in the game Diep.io.
Tier One Tanks (Lv. 1)
Basic Tank
The most basic tank, which all players start off as. Has all-around and surprisingly high stats. Tier Two Tanks (Lv. 15)
Twin
Upgrades from the Basic Tank. Grants an extra gun at the cost of some damage/penetration.Flank Guard
Upgrades from the Basic Tank. Adds another rear-facing cannon to fend off would-be attackers who try to attack from behind.Machine Gun
Upgrades from the Basic Tank. Possesses a drastically increased fire rate in exchange for lower damage and poor accuracy.Sniper
Upgrades from the Basic Tank. Increases the field of view while giving you faster shots, but lowers firing speed. Tier Three Tanks (Lv. 30)
Triple Shot
Upgrades from Twin. Three spread-out cannons cover a wide area but have lower individual firepower.Quad Tank
Upgrades from Twin or Flank Guard. Four cannons along the cardinal directions fend off attackers from all fronts, but have lower damage.Twin Flank
Upgrades from Twin or Flank Guard. Mirrors the Twin's dual-barrels on the tank's rear for excellent defense on both sides.Tri-Angle
Upgrades from Flank Guard. The back cannon splits into two small guns, which deal little damage but can propel the tank at very fast speeds.Auto 3
Upgrades from Flank Guard. Possesses three weaker but automatic turrets that track and fire at the nearest enemies, and can also be manually controlled by clicking with the cursor.Destroyer
Upgrades from Machine Gun. Has a poor rate of fire but fires gigantic bullets with huge recoil. A Destroyer's bullet is slow, but nigh-unstoppable and incredibly damaging.- Difficult, but Awesome: If you can get around its slow rate of fire, you'll see yourself absolutely destroying everyone.
Gunner
Upgrades from Machine Gun. Four barrels unleash a hailstorm of bullets, but each shot has far less power.Assassin
Upgrades from Sniper. Further increases your field of vision but lowers your reload speed again.Overseer
Upgrades from Sniper. This unique tank can control up to 8 auto-replenishing drones to fight for it using more complex controls. The drones are very powerful, but the tank itself is defenseless.Hunter
Upgrades from Sniper. Slightly increases your field of view while allowing the cannon to fire in two-round bursts. Individual bullet damage is slightly reduced.Trapper
Upgrades from Sniper. This unique tank fires short-ranged traps which will remain in place. Traps cannot move, but are incredibly durable and incur tremendous damage to anything that touches them.Smasher
Upgrades from the Basic Tank. Only attainable by keeping a Basic Tank until Level 30, the Smasher has no cannon but is allowed to invest up to 10 points in each body damage category instead of the usual 7 (total # of upgrades remains the same).- Collision Damage: A Tank that outright specializes in this type of damage to the point it doesn't even have a gun.
- Lightning Bruiser: Its high health and Body Damage make it incredibly resistant to bullets and allow it to dish out incredible amounts of damage to most tanks, even one-shotting most tanks that don't have maxed out health. It's also very fast.
Tier Four Tanks (Lv. 45)
Triple Twin
Upgrades from Twin Flank. Three evenly spread out twin cannons handle attackers from all directions, although its focused firepower is worse than the other Tier 4 Tanks.Battleship
Upgrades from Twin Flank or Overseer. Four spawners churn out small drones at an incredible rate, half of which are controllable and half of which are automatic. The drones are rather weak and short-lived, but don't underestimate their power in numbers.- King Mook: Inverted Trope; it's very similar to the deprecated Mothership, but is much less powerful. That being said, while its drones are continually produced but expire after a set time, the Motherships drones are very much here to stay.
- Death by a Thousand Cuts: Its drones deal very low damage, especially compared to overseer branch drones, but it produces them rapidly enough to become a deadly force in combat.
Octo Tank
Upgrades from Quad Tank. Eight cannons deliver an omnidirectional barrage of shots, but each shot is rather lacking in firepower.- Bullet Hell: Its firing pattern results in this, especially with a maxed reload speed.
- Multi-Directional Barrage: Its bullets fire in every direction around it.
Auto 5
Upgrades from Quad Tank or Auto 3. Five automatically-targeting turrets engage any foe in range and can be manually controlled, but it shares the same firepower problem as its predecessors...- Exactly What It Says on the Tin: It's a tank with five automatic turrets.
Triplet
Upgrades from Triple Shot. Three frontal cannons deliver incredibly powerful focused fire that can devastate anything at close to mid range.Penta Shot
Upgrades from Triple Shot. Five weaker, spread-out cannons devastate a wide, conical area in front of the tank.- Spread Shot: Not nearly to such a field-covering degree as the eponymous tank, but makes up for it with each bullet doing equal damage.
Spread Shot
Upgrades from Triple Shot. A whopping eleven barrels deliver a inaccurate bombardment of deceptively powerful bullets over a ridiculously wide area. Its middle cannon fires a normal shot, while the five on either side of it deal slightly less damage.- Spread Shot: Did the name give it away? It fires one big bullet, and couples it with a wide spray of ten gunner bullets that fan out and cover a colossal area in front of it.
Overlord
Upgrades from Overseer. An additional two drone spawners doubles its production rate, allowing it to regain its lost drones much faster during combat.- Simple, yet Awesome: It's merely an Overseer with double the amount of spawners; however this dramatically increases the Overlord's recovery rate and allows it to remain in sustained fights far longer than its unevolved counterpart.
Necromancer
Upgrades from Overseer. This bizarre tank has no weapons to call its own, instead needing to touch squares to "infect" them, turning them into its own drones which can then infect more squares. While it cannot generate its own drones and its infected minions are weaker, it can have a drone army up to 36 strong to swarm and surround enemies with.A note about the Necromancer is that Reload turns into Drone Count (+2 drones per point)
Manager
Upgrades from Overseer. This tank sacrifices half its drone production speed for a potent cloaking ability that activates when standing still (but deactivates when damaged or moving). With this, the Manager is able to operate behind the scenes, using its drones to confuse and kill foes without even showing itself.Overtrapper
Upgrades from Overseer or Trapper. Is essentially a Trapper that can summon up to two automatic drones to defend it.- Bread, Eggs, Breaded Eggs: You have the overseer, the trapper, and the overtrapper. Simple as.
Factory
Upgrades from Overseer. This strange tank can command up to 6 specialized drones which have small guns of their own. It relies solely on these mini-tanks to defend itself, but the drones are deceptively durable and have very high combined firepower.- Drone Deployer: Unique in that said drones are basically miniature tanks.
- The Minion Master: Again, their drones are mini-tanks.
- Mighty Glacier: Its drones are very slow compared to other drones, but their cumulative durability and bullet power allows this tank to outpenetrate and overpower essentially every other tank in the game. Its fitting that the minions resemble miniature arena closers more than anything else.
Ranger
Upgrades from Assassin. The field of view is increased even further, allowing the user to deal out swift kills from a distance where most won't even be able to see what hit them.Stalker
Upgrades from Assassin. This tank has faster bullets and a cloaking ability that activates when still and will deactivate when attacking (or taking damage/moving). The combination of long-distance attacks and its stealthiness allows it to swiftly assassinate opponents from seemingly out of nowhere.Booster
Upgrades from Tri-Angle. An additional 2 back cannons provide much more thrust, allowing the Booster to easily outstrip nearly every tank in the game.Fighter
Upgrades from Tri-Angle. A specialized variant of the Tri-Angle designed for combat, two added (but weaker) side cannons provide extra coverage as it uses a combination of speed and power to track down and kill opponents.Hybrid
Upgrades from Destroyer. Adds a spawner that creates up to two automatic drones, which will seek out and attack any foes that draw near.Annihilator
Upgrades from Destroyer. Recoil is increased, but the cannon's bullets are now twice the size, making avoiding them all the more difficult.- BFG: Its cannon is as wide as the tank's body.
- Painfully Slow Projectile: It's super devastating... if it hits.
- Recoil Boost: The knockback from firing an Annihilator's cannon makes it one of the most popular non-Smasher tanks for a melee build. Even for ranged builds, the kick from an Annihilator shot can be used to make a quick getaway.
- Lightning Bruiser: Its immense recoil makes it one of the fastest tanks in the game, and it has spectacular firepower to boot.
Skimmer
Upgrades from Destroyer. Fires unique bullets that spin wildly while firing 2-way streams of smaller bullets. Its overall damage is much lower but it can now cover a much larger area.Rocketeer
Upgrades from Destroyer. Fires strange rounds which will accelerate shortly after being fired, using a small machine gun in their rears. Its damage is lower, but once its rockets get going they will reach their targets much faster than usual.Predator
Upgrades from Hunter. The tank now fires in a more damaging three-round burst and has the unique ability to extend its field of view in a chosen direction. This ultra-long-range ability allows you to target foes before they even know your position.- Difficult, but Awesome: Fires a three-round burst which takes some knowledge to truly understand, and couple with their unique "zoom" feature. Predator gameplay relies on the ability to adjust focus at a moment's notice, as well as creating a firing pattern capable of oppressing whatever enemy it faces.
Streamliner
Upgrades from Hunter or Gunner. Five overlapping barrels produce an absurdly fast stream of bullets. Each shot deals low damage, but anything that is exposed to its stream beware.- More Dakka: As an ultimate evolution of the Gunner, it's the king in this department.
Tri-Trapper
Upgrades from Trapper. Three trap deployers lay down traps incredibly quickly and over a wide area. While its traps are short-lived, it is more than capable of setting up what amounts to a fortress in a very short time.Mega Trapper
Upgrades from Trapper. A slower fire rate balances out the ability to deploy massive traps, which are absurdly durable and will incur damage comparable to a Destroyer should they hit something.Gunner Trapper
Upgrades from Trapper or Gunner. Two small cannons at its front supplement its rear-mounted trap deployer. While its guns are rather weak, the combination of offense and defense make it a versatile fighter.Auto Trapper
Upgrades from the Trapper. An added auto-cannon targets foes that approach this tank, bolstering its defensive power further.Landmine
Upgrades from Smasher. This tank has the ability to cloak itself, allowing for sudden ramming ambushes from out of nowhere. Beware - this tank takes a whole ten seconds to cloak, and it will still be dispelled by movement or damage.Auto Smasher
Upgrades from Smasher. An added automatic gun gives the Smasher its ranged firepower back - while still allowing up to 10 points in each stat.Spike
Upgrades from Smasher. A further increase to its already-high body damage makes the Spike an incredibly formidable melee fighter.Sprayer
Upgrades from Machine Gunnote . Unleashes a condensed but inaccurate spray of variously-sized shots in an area in front of it.Auto Gunner
Upgrades from Gunner or Auto 3. An additional auto-cannon on top of the tank bolsters the Gunner's firepower. Polygons
Square
The simplest shape, which has the least health and gives the least points. Can be captured by Necromancers for use as minions.Triangle
The second simplest shape, which provides a moderate amount of points when killed.Pentagon
The largest and most uncommon of the normal shapes, they have quite a bit of health and give a lot of points if destroyed.Alpha Pentagon
Massive Pentagons exclusively found in the "Pentagon Nest", which is in the center of the map. They have incredible HP and are protected by respawning Crashers, but will provide insane amounts of points when killed.Crashers
Small pink triangles which come in both small and large types. They spawn in the Pentagon Nest, guarding the Alphas by slamming into any tank that draws near. They provide small amounts of points to those who destroy them.- Ramming Always Works: And it hurts!
Rare Polygons
Incredibly elusive green variants of the three basic shapes which only appear once in a blue moon. They have very high HP and will grant immense amounts of points to their killers.- Metal Slime: They don't necessarily run away, but fit the bill for pretty much every other aspect of this trope.
Bosses
Massive tanks which naturally spawn ever now and then. Incredibly powerful, these bosses each pack 3,000 HP and immense firepower, but will reward you with 30,000 points if you kill them. All bosses (except the Fallen Booster) don't actively hunt players, and won't even target players below Level 15 unless they are provoked.
Guardian of the Pentagons
A boss resembling a massive Crasher. Packing 3,000 HP and a constant stream of Crashers ready to swarm its attackers, this boss slowly circles the arena while maintaining its Crasher army.Summoner
A boss resembling a giant square with four spawners. It has 3,000 HP and has a rapidly replenishing army of square drones at its disposal, which can quickly overwhelm even the hardiest of bullet spammers. It circles the map aimlessly until it is killed, slowing down to engage any players it finds.Defender
A boss resembling a giant triangle bristling with weapons. Boasting the standard boss HP of 3,000, this behemoth uses three auto cannons to gun down any opposition, while its three trap deployers create a wall to block off any shots that come its way.Fallen Overlord
A boss tank that looks like a giant, grey Overlord tank. Commanding a swarm of triangular drones, it uses them to swamp any tanks that threaten it (although it can't have as many out as the others). As a Fallen boss, it targets all polygons in range and is targeted by base protecters and Crashers.Fallen Booster
A giant, grey, AI-controlled Booster tank that threatens with both rams. Incredibly fast and hard-hitting, it has the distinction of being the only boss to actively chase players, not stopping until either of them dies or moves out of range. As a Fallen boss, it goes after polygons and is targeted by base protectors and Crashers. Other Tanks
Arena Closers
Massive, yellow tanks that appear to sweep a server clean before a restart. As such, they are the epitome of Purposely Overpowered: incredibly fast, impossible to kill, and packing enough damage to One-Hit Kill the hardiest of tanks.- Gold-Colored Superiority: Yellow tanks with absurd stats that exist only to kill everyone in a server.
- Lightning Bruiser: Gigantic, fast, invincible, and capable of instantly wiping out any player with one shot from their blisteringly-fast bullets. No one can last long against an Arena Closer, which is entirely the point.
- Tiebreaker Round: Their appearance heralds a sudden death rule being applied to the current game; any player that dies (not necessarily by an Arena Closer, but very likely) is booted out of the server.
Dominators
Stationary turrets that function as control points in Domination Mode. Starting off neutral, teams must destroy it to convert it to their side, upon which a team member may take control of it. To take it back, a team must destroy an enemy Dominator to revert it back to its neutral state, then kill it again to claim it. Victory belongs to whichever team takes all the Dominators first.Statistically, the Dominators are Level 120, have about 6,000 HP, and come in three variants: one with a slow but immensely powerful cannon, one with a rapid-firing machine blaster, and one with 8 trap deployers.
- Artificial Brilliance: AI-controlled Dominators are capable of leading their shots, potentially sniping anyone who thinks they can just brainlessly strafe around it.
- Mighty Glacier: Dominators are immobile, but have a lot of firepower to help defend themselves.
- Weaksauce Weakness: While their attacks are devastating, Dominators do not have the range nor bullet speed to be super oppressive. It's entirely possible to just snipe a Dominator from outside its effective range; while tedious, it will eventually fall.
Mothership
A massive, slow tank that starred in the now-defunct Mothership mode. Both teams would have a Mothership (controlled by a random member of their team), and the objective of the mode was to destroy the other team's Mothership to claim victory.The Mothership itself was Level 140, had about 7,000 HP, and threatened with 32 regenerating and tough drones: half of them automatic and half controlled.
- Drone Deployer: Motherships were basically a gigantic Overlord in terms of mechanics.
- Macross Missile Massacre: What being attacked by a Mothership looks like.
