Here we go with another DWD mystery
In the episode "Heavy Mental", Maj. Synpase turns into a gigantic brain when zapped by the Norma Ray. But this didn't happen to Launchpad or the two teenagers the ray was also used on. Why not? I think it's because the ray must affect a person differently when they use it on themselves, rather than someone else operating it. Sort of like the difference between tickling yourself and being tickled by another person.
