Any of the toys that were turned into Converters
Anything named VF-__ that either doesn't transform or only has two modes ie. Converters, and the Matchbox Veritech (that word hurts my eyes)
Toynami's VF-1 MPCs. Loose, Ugly, Crap
Yamato 1/60 V.1 and the old Bandai/Revell Robotech models. VF-1s should not require nosecone swapping and/or leg removal
Banpresto VF-1, slightly prettier than the MPCs but even looser and if you can believe it, crappier
