Necrolai became human in 2006 so she should not be on Sledge's ship in 2015 in a monster form she has not had in 9 years.
The Rex suffix on the Red Ranger's Zord is misplaced: they got right in Power Rangers DinoThunder (2004) because they didn't use it or for a real life outside of show reason the Rex suffix has still being incorrectly used for the tyrannosaurus dinosaur today even after they found a bigger, heaver and more powerful dinosaur in north Africa Spinosaurus. so anyone using the Rex suffix is wrong. EDIT: This is incorrect use of taxonomy. "Tyrannosaurus rex" is actually the proper scientific name, ideally written in italics and the lower case R in rex is correct. Larger, more powerful dinosaurs mean nothing to taxonomic nomenclature.
The helmet on the Silver Ranger has an error the yellow surround around the visor is wrong, it has the triangle shapes denoting the teeth of a carnivore when the titanosaur was a 50 ton herbivore.
The monsters Loafer and Scumlaw are inexplicably never Magna Beamed.
It is established that Zenowing built the Zords, and that the Titano Zord requires all 13 auxiliary chargers. But there is no way that Zenowing knew in advance that the Rangers would create these chargers.
When a Ranger morphs, an energy manifestation of their Zord's head appears, which doesn't make sense considering the energems preceded the Zords.
