Ed Driscoll
From Tardis Wiki, the free Doctor Who reference
Ed Driscoll was leader of the tree fighters. He took medicine from David McCallister's compound but didn't know how to use it until the Sixth Doctor showed him. When a rogue time sphere, used by the Doctor to protect Earth from meson dissemination, grew out of control, it absorbed Driscoll and killed him. (AUDIO: Blue Forgotten Planet)
