Malodor's original name

Before episode 13 of Season 1 started (yeah apparently,Out of focus is meant to be episode 13 instead of 14),the plot of the episode was revealed and the name of the Decepticon was Stench. When the episode aired,the Decepticon's name was Malodor. Well,what if I tell you that Stench was Malodor's original name? And beside,this is not the only times this ever happen. More examples are Prong and Chicane,who turned out to be Crustacion and Nightra.
