8. Slag
You probably guessed the reason for this as soon as you read the name of this entry. The word 'slag', by definition, is a "stony waste of matter separated by the smelting or refining of ore." Hasbro probably intended the name to be reminiscent of this, and not "a derogatory term for a promiscuous woman." 'Slag' is, after all, a common insult used to describe females of such a description in the UK. Going ahead with this character would likely result in the dinobot becoming a laughing stock of sorts in British cinemas. Keeping in mind that the next movie is titled Age of Extinction, and that the teaser poster depicts a dusty, fossil-like logo, the dinobots (a division of the Autobots who transform into dinosaurs, such as Grimlock) are likely to appear. Hopefully the version in Michael Bay's next instalment won't be voiced by a woman, then.
