And all three are non-infinite species that have been utterly eradicated, mostly by each other. If they join forces to wipe out everyone else, that's curtains.
The Whoniverse's power level is highly erratic, but it's potential is pretty much insane.

If the Time Lords were still at their height they'd be able to mass produce demat weaponry, which IIRC unmakes and then remakes the universe exactly how it was, except that the matter that composed you doesn't exist anymore (which is probably one of the things the Moment can do). That's not getting into Gallifrey's timeback buffers (I think that's the name) nullifying any attempt to change the Time Lord's history, Null Zones to turn off time travel in areas measured by galactic features, or whatever the Celestial Integration Agency has cooked up. Or that slow time thing from The War Games

And of course the Time Lords have the ability to set up their technology so that their support kicks in at exactly t=0. Even without Daleks piloting battle TARDISes suddenly the parts of time you wish to change aren't accessible, until the timeline of Gallifrey advances to the point that they want to mess around in that place and time.

The Whoniverse isn't unbeatable, but it's pretty hard even if we throw out beings beyond the Time Lords (*cough* new series *cough*). It benefits from poor understanding of science in the early days caused it to feature galaxies when it meant to feature solar systems, and the new series is sometoimes legitimately universal in scope.

Bah, if we're allowing the Qs we're allowing both the Eternals (beings who are to the Time Lords as the Tine Lords are to us), as well as the Guardians.
