10 Doctor Who Characters Who Almost Had Different Endings

6. Ood Sigma Was Meant To Fight At Demon's Run

The Ood don't exactly look like the friendliest of chaps, but if you show them some respect, they'll respect you in return. Or, if you enslave them and treat them like dirt... well, then they might just murder you with their electric ball thingies.

Wisely, the Tenth Doctor chose that first option, helping to free the Ood in Series 4's Planet Of The Ood. This led to him gaining an ally in the form of Ood Sigma, one of the more intelligent members of Ood-kind. Sigma then showed up to wave the Doctor off just before his regeneration, and after this, he was never seen again.

However, Sigma was supposed to be present during the Eleventh Doctor's era - specifically, in Series 6's A Good Man Goes To War.

Here, the Doctor calls in favours from various different friends of his: he recruits Dorium Maldovar, Madame Vastra, Jenny, Strax, and others, all in an effort to rescue the recently-kidnapped Amy Pond from the fortress of Demon's Run, and originally, Sigma was meant to be another addition to this eclectic band of personalities.

Writer Steven Moffat wanted Sigma to fight off the Headless Monks by hitting them with a mental assault, in the form of an Ood song. This plan came so close to happening that the scene wasn't dropped until the editing phase, and interestingly, the episode's credits still list Russell T Davies as the creator of the Ood - even though the aliens don't actually appear in the episode.

Danny has been with WhatCulture for over ten years, and is currently Doctor Who Editor and WhoCulture Channel Manager, overseeing all of WhatCulture's Whoniverse coverage. In 2022, he took charge of WhoCulture and has grown it into the biggest Doctor Who channel on YouTube, and one of the biggest Doctor Who communities on the web full-stop. He has been writing and video editing since his early teens, and first got a taste for content creation after making his own Doctor Who trailers, off the back of a burning obsession with the Matt Smith era of the show. Like many his age, he first got into Doctor Who with the 2005 revival, but has since gone back and fallen in love with the classic years too. If you need someone to recite every Doctor Who episode in order, or to give you a random factoid about the making of Gridlock, Danny is the person to ask!
