Boaz

Boaz was a guerrilla fighter and part of the human resistance opposing the Daleks from an Alternate Earth future.

He was part of the group led by Anat that traveled back to the 20th century to kill Sir Reginald Styles. At first he refused to believe that the Doctor was not Sir Reginald Styles and wanted to kill him instantly, but was prevented from doing so by Anat an action that put him at odds with her for the rest of the mission.

When the Doctor traveled with them to the future, he refused to help him find Jo and left him to fend for himself. He did however participate in a rescue operation to get the Doctor away from the Controller’s compound once they realized his importance, an action which cost him his life. (DW: Day of the Daleks)
