I'm still curious about that nuckledragons fate from dark of the moon. Igor was last seen in Washington DC. Did lennox or anyone kill him?
Do you just expect someone to make something up for you? There is no canon answer. His existence was so entirely inconsequential that there was and is no reason to treat what happened to him as significant. Your guess is as good as ours.
According to the novel he was left behind by Megatron when he left Earth for Cybertron. Given that AOE and TLK likely don't take place in the novel timeline he's still alive there. The movies just threw him out after Sentinel's takeover of DC. He's either in hiding or killed by Cemetery Wind forces. Both are equally likely. As a head he's probably lost his transformational ability and therefore cannot disguise himself, but his size means he can just hide under unassuming rubble and avoid Energon detectors. Either way his existence was useless. Whether or not he lived wouldn't change the story in any way.
What the heck was he in the first place? Some AllSpark mutation? If that's the case then what happened to the mountain dew machine?
After the defeat in TF3 as a garbage truck, LongHaul changed alt mode to a truck to hide from the humans. But it was no use.
I feel like this describes the majority of new threads in the movie forums these days. A lot of people asking questions that pretty obviously have no official answers and won't ever be answered.
^This.Right.Here. 100!100! Also, the same can be said for many of the characters in the bayverse, especially the ones the films are named after. . .
Oh my god how could we have forgotten such a integral character his existence is ut most importantance!
