Speaking of large protagonists, me and my friend did some calculations for Metroplex, starting off ofMetroplex's scale.It's very clear that Optimus is tiny in Metroplex's hand but still very visible, so we guessed Optimus was half as tall as one of Metroplex's finger segments. We then compared my friend's height (70") and the length of his finger segments (0.5"), so that's roughly 140 times smaller than he is. So if Optimus Prime (28') is 140x smaller than Metroplex, that would place Metroplex at 3920' or 1195 meters. This still makes a bipedal Metroplex smaller than your average Star Destroyer from Star Wars (with the average being quite low on their own size spectrum). This would hardly make Metroplex the size of a fully Transformer-scaled city, but it would make him a notable structure, like how he is in IDW. More like a bastion or citadel.Now, since Metroplex is roughly the same size as Trypticon, who transforms into the, we can say Trypticon's considerable bulk (whose still 1200 meters tall) goes more into his length when he converts into ship mode, especially if we go off his Prime iteration. With these numbers and the dimensions of a typical Star Destroyer, we found an average for how many crew members (gunners, soldiers and crew) Metroplex could have, and therefore Trypticon. It's roughly 2200 people, which totally jives with the idea that both Optimus and Megatron only took a "few" Transformers with them in their exodus from Cybertron.
