The one where the Doctor uses Aggedor to save the day...
The monster of Peladon doesn't really feature very much in The Monster of Peladon, does it? I mean, if you take the monster to mean Aggedor, the real Aggedor only appears in two brief scenes in the entire story, while its "spirit" isn't Aggedor at all, but a statue. Of course, the real monster of Peladon was probably Ettis, seeing as he was much more bloodthirsty and crazed than Aggedor ever was.
The Doctor uses Eckersley's matter projector to project an image of Aggedor outside of the refinery so that the heat ray can destroy the encroaching Ice Warriors. Amusingly, as soon as he sees his two pals disintegrated by the heat ray, Sskel scarpers like a frightened rabbit!
