No-nonsense Real World author Peter Dickinson has been trapped in a fantasy world for quite some time (in the body of a dragon no less), forced into a quest to defeat the Big Bad wizard, Ommadon (voiced by Darth Vader himself, James Earl Jones). Just when it seems the evil wizard has defeated the heroic band and all hope is lost, Peter (in mortal form) appears before him, polishing his glasses nonchalantly. While Ommadon transforms into a Hydra and attempts to intimidate him with threats of Biblical feats of magic, Peter defiantly refutes all magic as illogical and impossible. For every incantation Ommadon recites, Peter literally talks him to death, countering with proven scientific facts, eventually having the Red Wizard desperate and on the ropes:

When the wolf Aragh first appears and manages to single handedly save the group from the Sandmurk. All by running through the horde to get to their queen. Killing her by throwing her off a cliff, along with himself! He survives of course (mostly because he's technically dead at the moment), but it was still an awesome scene.
With the party slain and the protagonist under a sleeping spell, Sir Orrin Neville-Smythe, the Knight In Shining Armour, is the last one standing at the end, facing down the The Dragon Bryagh. He holds his sword up and recites a Badass Creed. He then gets set on FIRE, takes it like a badass and throws his now-flaming sword into the heart of the dragon, who burns to death in his own flames. Then Orrin dies alongside the rest of his slain party and newfound love.
