The Transformers Live Action Move Blog has posted a rumor sourced from noted Hollywood insider site Christian Today... which got it from Design & Trend... which got it from some podcast who got it from some random Facebook page ...that Ultra Magnus and the Quintessons will appear in Transformers 5. We're skeptical, for reasons we'll go into in the article - but this is notable because it means the TF5 hype train is underway. Keep reading for more details on this game of Internet Telephone!
File this under "grain of salt" but Christian Today (how is that for an odd source for movie rumors?) is reporting that one plot point being considered for Transformers 5 would introduce the movie version of the Quintessons and Ultra Magnus. Optimus Prime would meet the Quintessons, who in the movie-verse would be the Transformers creators, to get answers about why they wanted to kidnap him from Transformers: Age of Extinction. Part of the plot would include introducing Ultra Magnus who would have history with Megatron (now Galvatron).
We've tracked this story back a couple of steps. Christian Today cites Design & Trend, who cite Breathecast.com. All of whom you may note that you have never actually heard of. We didn't bother trying to source Breathecast's source, Comic Central CIty, because searching for specific posts on Facebook is awful. Beyond which, the Breathecast post dates back to late 2014, before the Transformers Cinematic Universe's writers' room was even assembled. We bring this to you both to announce that the TF5 rumor mill is well underway, and as an illustration as to how low-tier rumors propagate on the internet. We'll be reporting on the entire Transformers 5 experience and process (and gossip!) as information becomes available!
