Other appearances: both Mirage and Ironhide are 'legends' of the G1 Transformers Universe!  Whether or not these two are the same personality remains to be seen.  From what I've learned about RID, I'd guess they are like BW Megatron to the original; different individuals with the same names.

What would these characters have looked like in Beast Wars/Machines CGI? 
This art from the japanese cards gives us a glimpse!  Ah, how sweet it would'a been! :)
