The Mentor (Death to the Doctor!)

The Mentor was an overweight alien, described by the Third Doctor as a "second-rate impostor". The Mentor himself claimed that his name was not a copy, but "purely coincidental".

He encountered the Third Doctor, who remained unimpressed, and the Brigadier, who pulled a gun on him.

Later, he appeared at Research Base Truro, where he met with several other aliens the Doctor defeated in his various incarnations, who turned on each other as a result of their mutual suspicion following the accidental death of Kraarn. The Mentor died in a three-way shoot-out with Bolog and Plink, two of the Doctor's other very minor enemies.

As with the others, when the Tenth Doctor arrived in Truro in the TARDIS, he did not recognise the body. (COMIC: Death to the Doctor!)

Behind the scenes
In an interview with Jonathan Morris released in The Widow's Curse the description for The Mentor was given as; "A low-rent Master. A man in his sixties who has gone to seed. Balding with a comb-over. Rotund with the tired-eyed look of someone who's had too many gin and tonics. His sinister black outfit is tight around his gut, emphasizing his beer belly". Several of the character's lines paraphrase those of the Roger Delgado.
