Another thought I'm obsessed with (and that hopefully you'll like since it involves your mans) is the idea that the Night Master WAS a former woo foo knight who became deeply disillusioned with woo foo and turned to the dark side because of it (and the Amnesulet helped in erasing this fact from public consciousness so that the secret could die with him).
and the reason he took the lengths he took to restore Yuck's body and power was because he saw that same woo foo renegade spirit in him and thought it would be a shame to deny him his chance at revenge
Ah yes! I remember that one! I have a similar headcanon regarding his involvement with Woo Foo, because I mean... he'd have to have SOME sort of background in it to have taught Yin and Yang anything regarding it, right? It's a little different than this, but the roots are there!
And "using Woo Foo in anger" really does fit Yuck's MO to a T, don't it? Little wonder NM clicked with the kid right away, to the point of orchestrating the means to get a kid a new body.
