Midvalley the Hornfreak is a violent musician who is able to use his saxophone, Sylvia, to synchronize sound waves with pain, causing physical damage. He also is capable of neutralizing sounds by playing counter-frequencies. He and his band originally just kill for money until being found by Knives, who kills all except Midvalley. He dislikes both Legato and Knives, which leads him to try to kill Legato, though he is quickly killed himself. Legato uses Midvalley's body to attack Hoppered, and it is buried with his saxophone on his gravestone afterward. He has a smaller role in the anime, mainly acting as Legato's bodyguard until fighting Vash, and killing himself after overloading his saxophone. (Source: Wikipedia)

The Great Toad Sage is the oldest and most respected toad of all the inhabitants of Mount My�boku. Because of his age, the other toads affectionately call him Great Honorable Geezer. He is famed for his highly accurate prophecies. Being several thousand years old, he is the oldest and most respected among the population of Mount My�boku. At his great age, the Great Toad Sage seems to constantly smile and tends to have his eyes closed or squinting. He is portrayed and described as being senile, and sometimes out of touch with his present situation, so he does tend to forget things easily and quite quickly. However, when reminded, he is still able to remember things and can easily tell things very precisely. As a sage, he is also very wise, and is quick to stop Shima and Fukasaku from bickering and encourages harmony. It would seem that unlike most other toads, he actually has respect for Jiraiya, and has urged both Shima and Fukasaku to cooperate with him
Tikal is the daughter of Chief Pachacamac from the same tribe that Knuckles the Echidna descends. She first appears in Sonic Adventure and returns in Sonic Adventure 2 as a bonus character. Thousands of years before the main events of the series, she opposes her father's power-hungry ways of invading other countries. She eventually comes into contact with Chaos and a group of Chao at the shrine of the Master Emerald, who accept her due to her friendliness to them. She tries to change her father's mind about raiding the shrine for the emeralds, but he refuses to listen. After Pachacamac raids the shrine, angering Chaos, Tikal recites a poem taught to her by her grandmother and figures out how to use the Master Emerald's power. She then seals herself and Chaos into the emerald. Several thousand years later, Doctor Eggman shatters the Master Emeralds and awakens the angry Chaos and Tikal's spirit. Tikal helps the main characters defeat Chaos, and then leaves with Chaos.
