Gwendolin believes there hasn't yet been a Bloon problem that can't be solved with fire. Lots of fire.
~ Bloons TD6

Gwendolin is a Hero in Bloons TD 6. She specializes in fire-based weaponry and is unlocked at experience level 14. She has short range, and her main attack is a medium-range fire blast from her flamethrower whose shots can pierce up to 3 Bloons. Due to her attack being fire based, she cannot pop Purple Bloons, at least until level 16. She is also unable to pop Camo Bloons without support, except with her abilities.

She costs $765 on Easy, $900 on Medium, $970 on Hard, and $1,080 on Impoppable.

In the 6.0 update, she was given a new skin, named Scientist Gwendolin, with new voice lines and appearance. She wears a blue and white lab tunic and her hair is blue instead of orange. She holds a purple potion instead of her normal fuel. The skin costs BloonjaminsIcon.png2500 to unlock.

In the 17.0 update, she was given a third skin, named Harlegwen. The skin also costs BloonjaminsIcon.png2500 to unlock.

Gwendolin's unique name tag, featuring yellow instead of blue.

Upgrades[edit | edit source]

Gwendolin will start upgrading herself every round upon placement. She earns more XP each round to unlock her next upgrade irrespective of how many bloons she pops. Her upgrades can also be immediately bought with cash, though the amount of cash required to purchase the next upgrade will typically increase as the upgrades get higher, making self-upgrading an important element for her overall power. As she is one of the original 4 heroes, her relative levelling speed to the rest of the heroes is 1x.

The following are the upgrades:

  • Level 1 - Blasts Bloons with fire from her pyro gun.
  • Level 2 - Slightly increases popping power per shot.
  • Level 3 - Unlocks Cocktail of Fire: Hurls a flask of flammable liquid, burning bloons that pass through the fire.
  • Level 4 - Heat it up - Every few seconds creates a powerful blast wave of fire that pops Bloons and adds fire to nearby Monkeys' attacks.
    • Periodically creates a powerful blast of fire around Gwendolin that pops Bloons, and adds fire to nearby Monkeys' attacks. This occurs every 30 shots she makes. This buff allows nearby affected towers to pop lead bloons and gives them +1 pierce.
  • Level 5 - Increased popping power.
  • Level 6 - Attacks can cause a burn effect on target bloon.
  • Level 7 - Heat it up has increased radius
  • Level 8 - Shoots 2 blasts of fire per shot.
  • Level 9 - Initial hit for per blast pops 1 extra layer.
  • Level 10 - Firestorm: Sets the whole screen alight, burning all Bloons and granting the Heat It Up buff to all Monkeys.
  • Level 11 - Increased attack range.
  • Level 12 - Increased attack speed.
  • Level 13 - Greatly increased popping power, plus projectiles move faster and last longer
  • Level 14 - Cocktail of Fire does extra damage and sets MOAB class Bloons alight.
    • MOAB-class bloons that come in contact with the fire take 50 damage over 10 seconds, and normal bloons have a burn effect applied to them.
  • Level 15 - Increased attack speed.
  • Level 16 - Firestorm has increased duration. Purple Bloons are no longer immune to Gwendolin's attacks.
    • Allows Gwendolin to pop Purple Bloons, and Firestorm lasts longer.
  • Level 17 - Heat It Up empowers affected monkeys to pop 1 extra layer, and do +2 damage to Lead Bloons.
  • Level 18 - Increased attack speed.
  • Level 19 - Shoots 3 blasts of fire per shot.
  • Level 20 - Firestorm does hugely increased damage.
    • The flames now inflict multiple layers of damage at a time to bloons and do 25 damage per second to MOAB class.

Activated Abilities[edit | edit source]

  • Cocktail of Fire - Throws a molotov cocktail, which generates a fiery explosion that burns any Bloon that passes through the flames (including camo bloons), and will continue to burn for about half the cooldown of the ability. When bloons are in Gwendolin's range, she aims it at the furthest bloons advanced. When there are no bloons in her range, or if there are camo bloons that she cannot detect, she throws the cocktail to a random spot in her range.
  • Firestorm - Covers the entire screen with fire, igniting all bloons. Burns about 2 layers per second and does 10 damage per second to MOAB class bloons, as well as triggering Heat it Up for all monkeys on screen. Increases burn to 5 damage per half a second on normal bloons and 25 damage to MOAB-class per second at Level 20.

Strategy[edit | edit source]

Summary[edit | edit source]

Following the 16.0 buff, Gwendolin has returned as a stronger hero as there is now a reliable way to trigger her buff. Her buff remains a solid choice for towers who appreciate both pierce rather than just pure damage, or more uptime on buffs, in which case Pat Fusty's Rallying Roar may be a better option.

One of her main advantages comes from beating difficult Ceramic Bloon rounds on her own at Level 10+, especially to the likes of Rounds 63, 76, and 78. With effective ability timing, she can help beat various difficult grouped bloon rounds with ease.

Tips[edit | edit source]

  • Her burn effect is a powerful ability she gains early on; putting her on 'Strong' targeting allows her to tear through early rounds, including popping leads, but be careful to defend from Purple Bloons.
  • Cocktail of Fire is a very powerful ability, being able to destroy entire Rainbow Bloons, however targeting is random and often unreliable for targeting bloons that have escaped through the primary chokepoint. (However she will throw the cocktail on the bloons she is targeting so timing it well can be very helpful) This is extremely helpful for early game and helps with cleanup later on.
  • Once Gwendolin hits level 17, her Heat It Up ability gives +1 layers of damage to all nearby towers, useful to buff nearby towers. Do make sure she is attacking as she needs to attack or firestorm for Heat It Up to activate. Placing her near the front (but not directly at the front) should allow her to activate her Heat It Up effect as often as possible.
  • Heavy ceramic rushes (especially on Round 63, 76 and 78) can be stopped very quickly with Cocktail of Fire and Firestorm.
    • For Round 63, placing a Cocktail onto the first wave then activating Firestorm on the second wave and then activating another Cocktail on the third wave should eliminate Round 63 with relative ease, but requires good ability timing.
    • For Round 76, she can activate her Firestorm can effectively cancel out the regrowth, burning the bloons faster than they can be regenerated.
    • For Round 78, she can easily use two Firestorms for both waves, as her Firestorm ability only has a cooldown of 60 seconds.
  • Firestorm does 25 damage at level 20, dealing heavy damage to all blimps and bloons on screen.

Trivia[edit | edit source]

  • At launch, Gwendolin was the only fully confirmed female monkey in the series. Prior to BTD6, the monkeys were male/female neutral, although Dart Monkey, Ninja Monkey, Wizard Monkey and Super Monkey are male in the Super Monkey Fan Club description, the Double Shot description, Wizard's name, and the BSM2 description respectively. Female monkeys also exist in Bloons Adventure Time TD.
    • As of update 18.0, the patch notes monkey, as well as Ezili, Adora, and Admiral Brickell are also female.
    • It has been confirmed that all monkeys except for heroes and the patch notes one are all genderless. [1]
  • Gwendolin was originally the only Hero to have her name spelled in yellow instead of blue in the preview images and wallpapers.
    • This was changed in v14.0 when Adora was added.
    • Admiral Brickell also currently has her name spelled in yellow
      • Coincidentally, the three of them are all female heroes.
  • Gwendolin's in-game quotes confirm the correct pronunciation of the MOAB Class Bloons; MOAB is said as one word (pronounced as "moh-AB"), while the BFB, ZOMG, DDT, and BAD are pronounced by their initials.
    • Despite this, Striker Jones and Quincy pronounce MOAB by its initials, so MOAB could be accepted both ways.
    • Before the 5.0 update, Gwendolin was also the only Hero so far who calls out the BAD by name.
      • This is no longer true due to the Cyber Quincy skin being introduced in 5.0.
  • Gwendolin used to be the most expensive hero, costing $900 on Medium. With the 2.0 update, Captain Churchill became the most expensive hero, costing $2000 on Medium.
  • Whenever a MOAB-Class Bloon appears, she always says "Burn it!", except for when a B.A.D. shows up.
  • One of Gwendolin's in-game quotes, "With enough fuel and air, everything burns!" is a possible reference to the Joker's quote from The Dark Knight; "Everything burns!"
  • Before 6.0, you could get Gwendolin to throw three Cocktails of Fire instead of one by having all Monkey Knowledge in the Heroes section and placing her near a 5/X/X Monkey Sub.
  • Gwendolin had made appearance in one of Ninja Kiwi's Facebook account posts regarding July 4th 2019. She is seen roasting grilled pineapples on the barbecue at night. She also holds a spatula and a glass of orange juice while a fireworks display is set. This could be a reference to the premium upgrade in BTD5. Link(Facebook Post).
  • In a blog post released on February 28 2020, in response to a user question, it was suggested that Gwendolin likes to roller skate.
  • Gwendolin is the second hero to receive a second skin.
