Although I do see where you are coming from in a sense he doesn't really lack foundation (unless we are talking about electric boogaloo). The boxing character was still within popping: he uses animation techniques to bring that character to life, which in my understanding still falls under the umbrella of what it means to be a popper, and he constantly uses speed control, ticking, strobing etc alongside grooves and other movements. His hits are consistent and he shows some of what most people I would say would think of as foundation for this style: Electric Boogaloo movements and some other elements of popping; Toyman, twists, isolations are used within his style, with the toyman being prevalent. Small amounts of tutting and waving thrown in to supplement. It's probably not the approach you're used to, but he definitely does have foundation and this is just from my understanding; I could be wrong in some areas

Saying he has zero musicality is a little bit disrespectful as well. Musicality isn't just beatkilling if that's where your understanding of the topic stops
