Think back to the series of Doctor Who that broadcast earlier this year, and imagine - aside from the last episode - the very worst thing about it.

Now, also cast your mind back to all the kids running round last Christmas with those Cybermen voice changer helmets seemingly permanently glued to their head (although, as a friend of mine speculated, it would have been far more entertaining if there was real glue in there).

Mix them both together, and you have 2007's very worst Christmas present: The Dalek Sec human-hybrid voice changer mask.

I'm sure, when the toy manufacturers first saw the early script, they leapt at the chance to do this. But they must, as many of us did, have sat dumfounded when Daleks In Manhattan was broadcast last Spring and the human/Dalek hybrid first appeared. Here was one of the most unconvincing mask jobs of recent time, replete with compulsory extra, half a dozen badly animated phalluses dropping from its head. Never mind Toys R Us, there's an argument that this one would do better in Ann Summers.

Retailing at £29.99 and out at the end of September, it's surely the must-not-have toy of the season. Expect it to sell by the bucketload, then.
