^ Here is an interesting thought...
We've been shown that The Rhino will be a mech (just threw up in my mouth a little) in TASM2. We've also been told that the character won't be a big part of this movie.
What we do know is that early in the movie a Russiian Thug is going to steal an Oscorp armored car and that some sort of cannister is part of the situation:
We also know that Peter gets the canister during the chase:
I was also previously thinking that this had nothing to do with the next pic, but now I know that it does:
So, it seems pretty obvious that the guy in the pic above is just some hired merc type guy working for Aleski. They steal at least one of these canisters. Are they voltage cells from Ravencroft like I first thought? Maybe, but we'll see.
Anyway, Spidey takes down Aleski and embarrases him, as shown below:
What is that on Aleski's shorts?
So, this will somehow lead to Aleski wanting revenge and getting it (possibly with the help of Oscorp) by using this:
Again, just threw up in my mouth a little...
Kind of reminds me of:
"Lets go, Voltron Force!"
Anyway...
We have to assume that Mech-Rhino will be taken down by Spidey, which will enable us to focus more on Electro.
Now we also know (from my other thread) that the chamber with (at least) six doors will open to an outer chamber where this is shown:
So, we have to assume that this will lead (as I speculated many months ago) to the Sinister Six AND that each of these (at least) six doors are for the gadgetry of Sinister Six characters. We have been shown Doc Ock's arm harness and Vulture's wings. I've speculated other possbilties in my other thread, such as Scorpion's suit (different enough from Ock's), Shocker's gloves, Venom's symbiote, even Mysterio's Fish Bowl suit, and of course, Goblin's glider and stuff (leading to Harry becoming the Goblin - again just threw up in my mouth a little).
At the same time many of us believe that Rhino will be part of the Six. Of course, after Mech-Rhino is beat by Spidey (assumedly) why bring him back?
But what if one of these rooms is a cross species thingee with a rhinoceros? Even if not, what if at the end of TASM2 Aleski allows himself to go through a cross-species experiment to give him the invulnerable skin of a Rhino, along with the enhanced strength and speed? Just a thought that may not pan out, but it would be a way to keep the Rhino fresh for TASM3. Actually that would have been the better way to do Rhino, so it's not likely that that is what we'll get...
Either way, the trick to figuring out which characters will make up our Six will be figuring out what is in each of these (at least) Six rooms...
And it makes sense that each room has something material that is iconic towards a specific character. Some have stated that there are more than Six chambers, and there may be, but if we try to Six and get more, great. So what can be in each of these rooms and be iconic enough to be obvious for a certain character. We already have three (Ock, Vulture and Goblin), so what are the others?
