Tía Pikachu

As of May 2021, she has used seven Pikachu suits, since "the chemicals in the water from the riot trucks deteriorate the fabric with which it is made."

On 16 May 2021, she was elected as member of the Constitutional Convention for the 12th district with 20,935 (5.64%) votes in her favor.

On 23 February 2020, she participated in a routine of the impersonator and comedian Stefan Kramer at the 2020 Viña del Mar festival. By February 2020, she had made a national tour visiting the cities of Concepción, Valdivia, and Osorno, among others. As of March, she had participated in charity concerts with Anita Tijoux and the 31 Minutos characters.

On 8 March, during a commemoration of International Women's Day, Grandón was shot with a rubber bullet in the foot during clashes with Carabineros police forces. During the following months of 2020, she continued to participate in public social activities and demonstrations.

On 31 October 2020, she was attacked by the Carabineros while she was participating in a demonstration on the side of the Pío Nono bridge. During the conflict, her suit was ripped open, she was punched in the face by a Carabineros officer and was doused with pepper spray.

In mid-2019, Grandón's son, who was 7 years old at the time, had picked out his father's credit card and bought 600,000 Chilean pesos' (about 800 USD) worth of Detective Pikachu merchandise through a phone call. Seeing how they were unable to get a refund, Grandón and her husband planned to sell the items, but kept an inflatable Pikachu costume to use for Halloween. They later attended what is now considered to be the largest march in Chilean history, where 1.2 million people protested, with Grandón wearing the Pikachu costume. She became known as "Tía Pikachu" due to a series of viral videos of her dancing during the protest.

The viralization of the videos led one of her daughters to create an Instagram account for the character; in 24 hours, the account already had more than 24,000 followers. Her participation made her one of the symbolic characters of the large-scale demonstrations in which she continued to actively participate between October 2019 and March 2020.

Grandón began working as a school bus driver in 2015, providing services for a school in the Peñalolén commune. Before the social outburst, she lived at Lo Hermida neighborhood in the same commune, where she and her family were preparing to move to Piriápolis in Uruguay to look for new opportunities.

She worked as a vendor and a door-to-door saleswoman and later studied a technical career in early education, which she began to practice in 1996 at the National Board of Kindergartens, where her work consisted largely of educating and caring for children at social risk in their early childhood. In 2020, Grandón said in a YouTube live video that working as an educator was a difficult period in which the educators witnessed crude stories and experiences of their young students, who were at social risk.

Giovanna Grandón was born in Santiago de Chile as the eldest of four sisters. From an early age, she helped her single mother with housework and taking care of her younger sisters. In her adolescence, she met Jorge Millán Abarzua, with whom she married in 1993 and had a daughter and three sons.

Giovanna Jazmín Grandón Caro (born 6 May 1975), also known as Tía Pikachu (Aunt Pikachu) or Baila Pikachu (Dance Pikachu) is a Chilean preschool teacher, political activist, and politician. She obtained great attention during the 2019 Chilean protests, mostly due to her wearing a costume of the character Pikachu from the Japanese media franchise Pokémon. On 16 May 2021, she was elected as a member of the assembly that will write the new Chilean constitution as a response to the 2019 protests.
