Not strictly a never-realised-about-transformers moment but I recently shepherded my TRU MP(03) Starscream from Perth to Melbourne and started to re-appreciate the effort the designer put into the underside of the Jet mode. Its well sculpted and sleek in comparison to MP-11 and especially more recent Combiner Wars stuff (lookin at you Silverbolt!).
If you think about it, pretty much all transformers look awful from the underside, it's just that the cars and trucks and similar vehicles have more 'skin' to hide the ugly truth..
the aircraft, like MP Screamer and friends, Lugnut, movie dirge and others that actually look whole in their Vehicle modes are truly marvellous feats of engineering.
Is warrior class Megatronus supposed to be a triple changer?
While at lunch my son created this to fly around the Yum Cha table...
"Hey mum, look Megatronus is a jet as well!"
Is that just his creative imagination or do you think there is something to it?
First thing that came to mind when I saw it was a simplistic version of the jet Megatron turned into in Transformers Prime.
