I think it's mentioned somewhere that a sufficiently powerful portal CAN allow Voidsent to pass bodily across the rift, but such a thing is rare enough that EVERY Voidsent we encounter on the Source can be assumed to be a Voidsent's spirit animating a Source body, unless we're explicitly told otherwise.
And yeah - unless they're explicitly confirmed to be Dragons, we can assume Hydras aren't dragons. They're dragon-like certainly, but just about any lizard can be said to be so (raptors, efts, etc).
