Andrea

Andrea is the Ninth Pokémon to join Lincoln's team. And she's a Ground-type female Sandshrew, before given her a nickname. Andrea is currently Level 20, has a Calm nature and has the Ability Sand Veil. Her known attacks are Magnitude, Defense Curl, Rollout, Fury Cutter, Rapid Spin, Swift and Rock Tomb.

History
She first appeared in 'The Moon Stone' where Lincoln gave her water to save her from dehydrating.

Growing attached to Lincoln after befriending him, Andrea decided to leave the cave of Mt. Moon.

Upon meeting him again, Andrea, alongside Astro, offered to join the growing ranks of Lincoln's team.

In the chapter 'The Hidden Village', she along with Pikachu and Bulbasaur, manage to easily defeat the Team Rocket Trio. It is also in this chapter that she earns her nickname, which according to Lincoln, is based on the San Andreas Fault which has something to do with the Earthquakes of the United States.

In 'Electric Shock Showdown', she was Lincoln's 2nd choice for his Gym Battle against Lt. Surge where she battle against his Elekid after the Electric Type defeated Firestorm. After a tough battle that nearly destroyed the battle field (for a second time), Andrea came out victorious before asking Lincoln if she can take a break, since she had gotten very tire during the battle, and watched the match between Pikachu and his evolved form, Raichu.
