Astro Bot: Walkthrough & Boss Guide

Attack Patterns

PowerPyx describes Mighty Chewy as throwing three red pillars at the rooftops, pushing glass walls at you, tearing the roof apart and sending orange shockwaves.

Strategy

Get the dog power-up, then go forward to trigger his appearance. Jump from roof to roof to avoid the pillars, boost through the glass walls, and jump between the two halves of the roof when he tears it apart. Boost into his bell to stun him and hit his eye, then boost into his teeth repeatedly until they all fall out and hit his mouth to finish him. The reward is the Spike bot.

Attack Patterns

Game8 lists Targeted Tentacle Punch, Enemy Drop, Underground Tentacle Punch, Urchin Roll, Charged Tentacle Punch, Ink Bomb plus Enemy Drop, and (in phase 2) Urchin Rain. Ink puddles slow your movement.

Strategy

In phase 1, hit Wako Tako's gloves twice after a tentacle attack, pull both tentacles with the Frog Gloves and release them to launch yourself at his face, then hit both sides of his head. In phase 2, swing across the platforming ledges with the Frog Gloves ahead of the rising tsunami; after Urchin Rain he lowers his eyes, which you hit twice and then pull and release. Game8 also notes that you can lure a tentacle into spilled ink to trap it.

What the guide describes

Gfinity says she is the third boss and that 100 Bots must be rescued to unlock the fight. Phase 1 starts with a toxic mist (jump onto the pillars); her Slither Attack is telegraphed by marks on the ground. When she drills into the ground the arena shrinks, so staying in the middle keeps you from being knocked off. After two chin strikes her tongue is exposed and you grab it to start phase 2, where two purple eggs roll around the arena. Other guides describe the tool and later phases differently, so treat the details as approximate.

What the guide describes

FandomWire says the fight is in Camo Cosmos, which requires 150 rescued Bots, and Mecha Leon first attacks from invisibility. The three stages share a similar pattern: a branch-shake that drops enemies, a barrage of fire orbs, then a tongue attack. After the tongue attack you climb the tongue and strike the uvula. In the third stage the platforms are fragile and the attacks more intense. Afterwards you grab his nose ring and launch it into space.

What the guide describes

Seeking Tech's no-damage guide has three phases. Defeat the small enemies quickly, turn into a ball to avoid pellet volleys and pecks, remove the vent's screw with a spin attack, use the power-up on the vent and head for the trampoline. In phases 2 and 3 you also dodge rolling birds and choose a wing side when the wings are exposed.

Overview

Space Bully Nebulax is the game's final boss; he tears the CPU out of Astro's mothership at the start of the story and is defeated at the climax.

Strategy

Per Seeking Tech, each roulette segment plays differently. Monkey: dodge the yellow circles and throw the pellets back at him. Octopus: inflate to pass low barriers and deflate for high ones. Frog: jump his hammer shockwaves, break the hammer and swing its head at him. Magnet: avoid the shadows, collect metal and throw it back. Dog: dodge the shadows, break his stuck sword and return the thrown handle. Skull: defeat the enemies, then spin again. After each power-up segment, run to the UFO, attack his hands and break the lock. When all locks are broken he returns for the final phase: hold R2 to aim, shoot down the objects he throws, destroy his ship and hit the UFO's core.
