Emerald with his Dusclops, Sudowoodo, and Sceptile
In Sneaky Like Shedinja, Sudowoodo battled as Emerald's last Pokémon in his fight against Greta. Due to Dusclops having weakened Umbreon, she was able to finish it off with one Low Kick, giving him the win with a score of two to five. Greta sends out her final team member, a Shedinja. Greta points out that although Shedinja is weak, its Wonder GuardAbility makes it so that only a few moves can hurt it. Emerald counters with Rock Slide, a move that can defeat a Shedinja, but it uses Endure to survive the hit. Greta refuses to let the last round end with an assessment, and has Shedinja fire off a Solar Beam at Sudowoodo. Emerald declares that he lost, but Todd points out that Sudowoodo is still able to battle. Todd edges Emerald to cheer for the Pokémon that have been fighting for him all this time. Although he struggles initially, Emerald manages to cheer Sudowoodo on and tells her to not give up. Sudowoodo smiles, and manages to stand back up. The battle ends, and with an assessment, Emerald wins with a score of four to two, earning him the Guts Symbol.
In The Final Battle VI, Sudowoodo joins the rest of Emerald's team in an attempt to attack Guile Hideout. Guile easily fights them off and begins attacking them, which forces Emerald to realize he truly cares about Pokémon. Seeing the change in his heart Jirachi grants his wish to free the Pokédex holders from petrification. After the final battle with Guile Hideout, she became acquainted with Gold's Sudobo.
Sudowoodo was initially shown as an angry and stubborn Pokémon, attacking Todd for accidentally pouring water on her. After Emerald calmed her down she became extremely loyal to him, and sought him out to join him. She cares deeply for him, once getting into a fight between his otherPokémon to see who would care for him.
