The real Commander Valiant Thor on TG (t.me/vvt369) and interviewed on Mary's report WeThePeopleNEWS on Rumble is very clear disclosing that the more Reptilian DNA these monsters have, like above 50%, then they start shape-shifting & start becoming a hazard to Children AND that the Alliance is watching them all very closely. This is why we see some of them "glitch out" on camera, because the camera catches either what is an inter-dimensional shift or a malfunction of their cloaking technology. I think it could be either or both. The raising frequency (Schumann Resonance) is surely affecting them to where they cannot hold their appearance in Human form, too. Also possibly due to the lack of Human DNA as food (adrenochrome) or a combination of all the above.
Deborah Birx once glitched out and her double rows of teeth became visible, for example. (I don't know why this vid says clone she isn't a clone...IMO, just Reptilian.)
