I wonder what Wingblade Prime would have transformed into? Based on all the late-season shots of him in his firetruck alt mode, I wonder if the wings have transformed to finally give us a proper firetruck or if it would have been as lame as the converting axe = firetruck that we already have.

I'm not too well versed in TF TV fiction between G1 and Animated, but I think the use of the medium to explain/justify repaints was very cleverly done here, specifically Shockwave, Soundwave and the Seekers. I must have them all!

Also...

Can someone save me the effort of re-watching the entire series and explain to me what is known to have happened (as well as what's suspected to have happened) regarding these protoforms? I remember them being mentioned here or there in the series and outside the series (D.J.Wyatt), but can't recall the details.
