One year prior to the start of the Black & White chapter, it was revealed that Gigi was the Tepig that was supposed to be given to new Trainers by Cedric Juniper, but ended up being liberated by N and ran away. Tepig was later found alone by White in the pouring rain, where White caught her.
Gigi first appeared in Lights, Camera...Action, as one of the Tepig White was supposed to bring to a Xtransceiver commercial shooting. Due to a mix-up, White accidentally only brought one Tepig instead of the two she was supposed to bring. After Black disrupts the shooting with his yelling, his male Tepig, Tep, notices Gigi in her Poké Ball and releases her. The two quickly befriend each other and start playing. White, realizing that since his male Tepig is the Pokémon that she is looking for, hires Black after he accidentally puts the company in debt after rescuing them from an attacking Galvantula. Due to her being an actress, Gigi is never seen in battle and is usually seen being protected by Tep, similar to how White is protected by Black.
Gigi going to N
In Gigi's Choice, Gigi and White are confronted by N, who knocks and traps White into the Nimbasa Ferris wheel in order to talk to her. After confronting her about the problems with the musical, he has his Servine grab Gigi. Gigi manages to free herself by fighting back and N comes to the conclusion that White had been neglecting her true strengths in battle, a fact that Gigi agrees to. When White decides that it is time to escape, she attempts to jump off the Ferris wheel and asks Gigi to do the same. Surprisingly, Gigi goes to N's side, shocking White who falls out of the car and onto the ground below. Gigi and N watch from the car as White lies on the ground, crying because of Gigi's betrayal.
In A Wretched Reunion, Gigi battled alongside Zorua against Black's Bo, White's Amanda, and Cedric Juniper's Samurott. Together, the three Pokémon managed to defeat both Gigi and Zorua.
Sometime before Team Plasma attacked the Pokémon League, N released his entire team, including Gigi. N told Gigi that she was free to pursue whatever dream she desired. Gigi chose to stay in N's room, where she encountered White after she had been teleported there by Hood Man. Gigi reveals that she has chosen to return to acting in show business, which she shows by playing with N's toys. Although White considers Gigi N's Pokémon now, she offers to let her return to the BW Agency.
In PS542, when White is approached by N, she sends out her team to defend herself, but Gigi and Amanda don't attack, as they immediately realized that N wasn't there to fight.
Personality and characteristics
Gigi and Tep
Gigi is an actress, and as such, does not battle. Instead, she, like White, relies on the help of others like Black and his Pokémon to help her when she is in trouble. However, unbeknownst to White, Gigi is actually a strong Pokémon that wants to battle but never gets the chance to because of her actress duties.
Gigi seems to get along with Black's Tep fairly easily as the two of them were almost never seen apart.
