Crossover Madness: GLaDOS Writes a Letter… to Princess Celestia

Ellen McLain, voice of the maniacal GLaDOS and well… pretty much everything else in the game Portal (the voice cast expanded considerably in Portal 2), is perfectly willing to have some fun at the behest of fans. Nowhere is this more apparent than here, when, after being handed a script for a letter to a fictional character she’s never heard of before, she read it faithfully in the character of GLaDOS, free for the internet to manipulate into a final robotic GLaDOS voice. The unfamiliar character? None other than Princess Celestia, ruler of Equestria.

Want to see the recording sans computer overlay, which is almost as ominous as the digitized voice? Venture on, test subject:
