|Only appearance:||Survival: Endless Levels, Co-op Endless and Last Stand: Endless (iPad only)|
|Special:||Crushes plants, throws Imp|
|Only appears in Survival: Endless Levels, Co-op Endless and Last Stand: Endless (iPad only)|
Giga-gargantuar is the second strongest zombie in Plants vs. Zombies (only Dr. Zomboss is stronger). It is a Gargantuar with red eyes that is only seen in Survival: Endless, Survival: Day (Endless), Survival: Night (Endless), Survival: Fog (Endless), Survival: Roof (Endless), Co-op Endless, and Last Stand: Endless (iPad only).
The Giga-gargantuar absorbs 300 normal damage shots and its appearance changes after 100 and 200 normal damage shots before dying at 300 normal damage shots or four instant kills. The Giga-gargantuar throws its Imp after 150 normal damage shots or two instant kills.
It has double health of a regular Gargantuar, allowing it to absorb 300 normal damage shots or four instant kills. The Cob Cannon is a good plant to have in the your arsenal. You just need to remember that you need to use Kernel-pults in order to use Cob Cannons. It is also a good idea to pack extra instant kills such as Squashes, Jalapenos and Cherry Bombs. After two instant kills or 150 normal damage shots, it will hurl an Imp into the your defenses, unless it is already halfway into their lawn. You should try to pack in as much instant kills as they can such as the Cherry Bomb, Jalapeno, Cob Cannon, Squash, and Doom-shroom with a Coffee Bean. Sometimes, a Giga-gargantuar will appear before a normal Gargantuar appears.
- If the Giga-gargantuar is killed by an explosive, its eyes will become white instead of red.
- Giga-gargantuar, Gargantuar, Giga-Football Zombie, Tall-nut Zombie and Dr. Zomboss are the only zombies that can survive an instant kill.
- The Giga-gargantuar, the Gargantuar, the Bungee Zombie, the Balloon Zombie above the pool, the Zomboni, the Catapult Zombie, the Catapult Baseball Zombie, Dr. Zomboss and ZomBotany Zombies are the only zombies whose heads do not fall off when killed or defeated.
- The Giga-gargantuar, the Zomboni, Dr. Zomboss, the Gargantuar, the Catapult Zombie and the Squash Zombie are the only zombies that can crush plants.
- The Giga-gargantuar, Gargantuar, Zomboni, Backup Dancer, Imp and Dr. Zomboss are the only Plants vs. Zombies zombies that do not have the word "zombie" in their names.
- It is unknown why there are Giga-gargantuars, but the imps which are thrown by them are not a giga variant.
- Giga-Football Zombie and this zombie are the only "Giga" zombies in Plants vs. Zombies.
- Both of them do not have almanac entries.
- It is unknown why it is called the Giga-gargantuar, because in mathematics giga means "multiplied by one billion" and it only has double the health of a regular Gargantuar.
- This also applies to the Giga-Football Zombie.
- It is the only zombie which is exclusive to the endless modes, excluding Vasebraker: Endless and I, Zombie: Endless.
