Did Marvel Just Tease This Popular Comic Book Character InThe Thor: Ragnarok Trailer?

Ever since Marvel and Disney dropped the Thor: Ragnarok trailer, it quickly became the most viewed trailer that the MCU has released, and it's easy to see why (see yesterday's post). But with the speed that some of the scenes were given, could it be possible that we may have missed some important information about possible upcoming characters that might appear in the MCU at a future date?  Take the above picture for example.  While most of us were focused on what was happening to Thor, did we miss this possible character in the background?


When you look at the trident, the first character that comes to mind is Namor, the Sub-Mariner.  There have been reports that Marvel owned the rights to the character, and other reports saying that they acquired them from 20th Century Fox.  Because he mainly paired up with The Fantastic Four in comic books, it was assumed by many that 20th Century Fox held the rights to the character, but that might not be the case.  Look at Quicksilver.  He appeared in both Avengers: Age of Ultron and X-Men: Days of Future Past/X-Men: Apocalypse.  Same character, two different movie studios.  There have also been rumors that Marvel is ready to give the guy his own full-length feature film, so could this be his introduction to the MCU?


One online site asked the question as to whether Marvel could have been so careless to include him in the trailer ruining the surprise, or did they do it on purpose to drum up intrest in the upcoming film?  These questions, of course, are only valid if this is, in fact, Namor. 


I guess we'll just have to wait until November 3, 2017 when Thor: Ragnarok comes out.
