Matchbox became the sole licensee of the Volton toy line in 1984. With that came the responsibility of importing the toys into the US and remodeling them to pass the safety regulations here. For example, lions' teeth were made more rounded, and missiles were removed. However, Matchbox wasn't in charge for long and lost its license due to an unfortunate incident where cases of lead were found in the paint of some Voltron toys. It is important to note that this incident occurred in 1986 and that the Voltron toys in-store today have passed rigorous testing processes.
