Grandma

Grandma is a character mentioned in Sonic Adventure and Sonic Adventure DX: Director's Cut.

Personality
Grandma was a pacifist and a peace-lover, and unlike her son, was against violent raids and attacks in surrounding areas. In fact, Tikal’s own personality and beliefs are a very similar to Grandma’s due to the latter tutoring the former.

History
Grandma was primarily responsible for raising her granddaughter, Tikal, passing down knowledge of their clan's legends surrounding the Chao, the Master Emerald and the Chaos Emeralds. Grandma passed all her teachings, including an old mantra, and pacifistic beliefs onto Tikal. In turn, Tikal loved her grandmother dearly and cherished everything she was taught, making her a peace-loving pacifist, and she would often contemplated her teachings.

When Grandma passed away, Pachacamac took over and directed their clan into a series of violent conquests of the neighboring countries.

Powers & abilities
As the former leader of the Knuckles Clan prior to her death, Grandma presumably would have had fine leadership skills and combat skills. She was also capable of harnessing Chaos energy from the Master Emerald via “Tikal’s Prayer”.
