List of Badges in Paper Mario TTYD
It is highly recommended to have Vivian join your party first before fighting Atomic Boo. Atomic Boo is also weak to fire moves, so Vivian's Shade Fist and Fiery Jinx moves are actually very effective against the big ghost.
Note that Vivian will join your party while progressing through Chapter 4.
The moment Atomic Boo hides its face, the big ghost will unleash a powerful attack the next turn, which can be avoided by using Vivian's Veil move to hide in the shadows.
You can use the Power Lift special move to increase your attack and defense powers to reduce the damage from Atomic Boo's attacks. Once your attack power is increased, use Power Bounce to deal high amounts of damage.
