The Mech Gargantuar

For the version in Plants vs. Zombies 2, see Gargantuar Prime.

Mech Gargantuar is a boss zombie in Plants vs. Zombies: Garden Warfare 2 and Plants vs. Zombies: Battle for Neighborville. It is a robotic version of the Gargantuar and has very similar characteristics to both it and the Giga Gargantuar. Piloted by an Imp, the Mech Gargantuar is heavily armored, and takes highly reduced damage from most attacks, making it harder to vanquish.

It is based on the Gargantuar Prime from Plants vs. Zombies 2.



  • Robo-Smash: Slams his dual telephone poles on the ground, doing electrical damage.
  • Robo Charge Smash: Similar to Gargantuar's Charge Slam, the Mech Gargantuar zooms towards the player with its rocket feet, and does an extremely damaging smash.
  • Pulse Shots: fires a burst of 3 electric shots at the player.
  • Time Bomb: Fires a bomb at the player that takes 4 seconds to explode, and deals around 30 damage.


  • Easy: 1400 HP
  • Normal: 2000 HP

Super Robot Wave

3 Mech Gargantuar icons on the slot machine

When the boss slots land on 3 Mech Gargantuar icons in Garden Ops, a Super Robot Wave will occur. Robo-Zombies replace all zombies in the wave, with some Zombie Heroes being replaced by customized Tank Commanders and default or customized Computer Scientists.


The Mech Gargantuar has similarities to both the Gargantuar and Giga Gargantuar. Similar to the Gargantuar, he can quickly rush towards you and slam the ground, and like the Giga Gargantuar, his ranged attacks and slam have electrical properties. Try to attack when it is about to launch a bomb; Although it does more damage, it takes a long time to explode, and the Mech Gargantuar remains idle while doing this. Use similar tactics as you would the Gargantuar, however, keep in mind that it is almost entirely armored, and takes very little damage when shot at. Always aim for the head: it's not only unarmored, but attacks also do critical damage.

On a Super Robot Wave, this can either be challenging or insanely hard. The hardest threats to look out for here, are the Robo Zombies. They all have a lot of HP and can take a while to vanquish just one of them. In fact, (depending if it's on harder difficulties) they can survive a direct blow-up from a Sombrero Bean Bomb or a Bigger Better Butter and they will still be running. However, good timed Corn Strike from a Garlic Drone can kill a few of them as the wave starts if you're a Cactus. Computer Scientists aren't much of a threat but they will heal up the Robo-Zombies and the bosses if not taken cared of soon.

The first thing you should do is to get on a rooftop or some other elevated ground, where the enemies can't reach you. They'll all be shooting at you though regardless but some elevated ground can help you out though. Prioritize the Robo-Zombies and Computer Scientists first as they'll all be hardest to take down first, then focus on the bosses. Sunflowers and Roses will have harder times surviving (unless you're Vampire Flower) due to their health. Citrons are slow movers but can use their ball-form to escape, however, remember that the bosses and robots will be tracking their way to you quickly. Torchwood is quite tanky and can take lots of damage but they move slow, so try to stick close to a Sunflower.

  • All Gargantuar melee attacks have increased in effectiveness.


Plants vs. Zombies: Garden Warfare 2

Plants vs. Zombies: Battle for Neighborville



  • When the Mech Gargantuar takes damage, a voice can be heard from the Imp piloting it.
    • The sounds the playable Imp class makes when hurt are audible alongside the new audio cues
  • This is the third zombie boss to not turn into a ragdoll when vanquished, the others being the Yeti Zombie and the Treasure Yeti.
    • Coincidentally, all three of these bosses are actually robots (not including the Imp inside the Mech Gargantuar).
  • Sometimes when he is vanquished, he won't explode and pieces of him will not appear. This is a glitch that sometimes occurs with the Yeti Zombie boss as well.
  • The Imp inside of the Mech Gargantuar appears to be smaller than the Imp class, for unknown reasons.
  • Despite being robotic, this zombie is not stunned for longer than usual by the Citron's EMPeach.
  • Although the Gargantuar Prime in Plants vs. Zombies 2, the zombie that this is based on, launches Bug Bot Imps (which is what the Future Imp is based on) from his back, the Mech Gargantuar instead fires a bomb from his back in Garden Warfare 2.
    • It is unknown why this is, as the regular Gargantuar in the Garden Warfare franchise fires an Exploding Imp from him back, and the Future Imp even has a self-destruct attack normally.
