Slight differences: As Skuld looks out to the stars, Belldandy's still memorizing the periodic table (or the order of the Dynasties in the Japanese dub).
The title has the picture of a train with the markings No. 0044 which happens to also be the episode number.
On-screen text: days before the end of the earth, 36,527,481,224,731.
That's over 100 billion years! Current estimates put the age of the universe at somewhat less than 14 billion years, plus or minus 120 million.
Gan-chan sings the closing theme song for his singing audition.
This time around, Skuld wears a white lab coat instead of a military uniform.
Running Gag: Belldandy crossing the screen with signs that say "Don't try this at home, kids!" She's very right about ingesting silica gel.
English dub/sub difference
When Gan-chan launches his first mecha attack, he is asked to push button B in the original sub, but button W in the English dub.
Continuity goof between sub and dub
The English sub names the mecha number 0, number 1, and Gan-chan's mecha is number 2. The English dub names the mecha numbers 1, 2, and 3. And then the dub refers to Gan-chan's mecha as number 2.
