Zombot Space Shuttler

The Zombot Space Shuttler is the boss of The Moon. It behaves similarly to the majority of bosses in Plants vs. Zombies 2. It can summon meteors and moonstones and awaken Zombie Moontians. It will flip its thrusters horizontally to burn rows of plants and zombies.

Suburban Almanac Entry
Dr. Zomboss really brought his A-game along this time around. His shuttle comes complete with a fusion generator, state-of-the-art ion-propulsion system, asteroid redirection beam, orbital stabilisers and a glossy sheen. It even has cable TV.

Strategies
Strong defence and splash damage is ideal to take out the Astronaut Zombie. The Cryochoke or other freezing plants are recommended to keep the Astronaut Zombie from reaching the front lines of your defence.

Trivia
