Beige Guardian

The Beige Guardian was a character who featured in a video game that Izzy Sinclair played on the Time-Space Visualiser. (DWM: Happy Deathday)

In this game he collected together every enemy of the Doctor's, it is unknown how long it took him to do this, or from what point in time he took them.

Later he captured the first eight incarnations of the Doctor and tied them up and placed them on a huge cake.

After leaving the 2nd, 3rd, 4th, 5th, 6th and 7th Doctors to go and fight against their enemies, he left the 1st and 8th Doctors tied to the cake. They both worked together to break free of it, and they both deduced that all the Beige Guardian was, was just a gathering of electrons and they destroied him with a Sonic screwdriver. All the other Doctors then reappeared by the cake.
