I see that many others have posted their ideas of what may happen in the movie, especially concerning Barricade and Bumblebee's rivalry/relationship, and I had a dynamic/concept/pretty much a quarter of a screenplay of my own. Obviously the red car has a chance of being Cliffjumper, but my idea for the movie would not include him. It would be more similar to the Iron Giant, with a singular robot protagonist, but the end would be far different with the introduction of Barricade. I figured that having Barricade loom in the shadows, perhaps never even appearing in the foreground while still being obvious enough to be noticed by audiences, (a bit more subtle than in MV1) would be in character for the espionage-heavy role that he's filled in 2/3 of his movies. I think a nice parallel to TF1 could be created in a scene later in the movie the audience gets an obstructed view of Barricade contacting (and hopefully name-dropping) Starscream or Soundwave, stating that 'we've located an Autobot and he might be able to help us find the Cube" aloud, not unlike Sam watching Bumblebee calling the Autobots to Earth.While the first few acts can serve as a time to soften BB's previously mentioned 'tough, soldier-like nature' and build the relationship between Hailee and Bee with direct interactions and flashbacks (hopefully some stuff during The War, like with DotM), the third act sees Barricade finally reveal himself to our main characters, and confront Bee and engage in a MV1-esque duel. Frenzy would attack Steinfeld in a similar manner to Sam, and I've been toying with the idea that while Barry stalks BB and Hailee on goofier adventures out of the base, or wherever she's hanging out, Frenzy can gain intelligence as an insider like Soundwave did in G1 after being accidentally picked up in an 80's boombox form early on in the movie. The fight with Barricade would end in Bee getting his ass kicked and be left temporarily incapacitated (maybe Barry's wheel-saw or first-movie game cannon shared through all platforms could be used to great effect) but Steinfeld using some of her tools or something to scare off Frenzy. Here's where this whole idea becomes a little different than what I'm expecting will actually happen, but I think it would be really cool. Barricade should use some technology, God knows how, but use something to extract a bit of knowledge regarding Archibald Witwicky, the Glasses, the Cube, Megatron,etc and then leave Bee to rot, believing him to be critically injured.Barricade would then speak to Steinfeld (optimally in a voice most similar to that in TF5 but with the MV1 vocal reverb to fit the more calm tone, especially when compared to stuff like "ARE YOU EBAY USERNAME LADIESMAN217?!?'), and begin to tell off Bee and the Autobots as cowards, lying about their intentions with the Allspark to try and persuade her that her new-found friend wasn't only a stoic, remorseless soldier, but a guy working for the morally unjust side. He'd go on for a bit, with Frenzy possibly poking at Bee for some relief, and the monologue would end when he lets loose a Freudian slip and accidentally begins to describe the Decepticons' plan as it is when asked by Hailee (who he's keeping alive because he doesn't want to arise the suspicion that Transformers exist and assumes that she'll be told off like Archibald), which cements her stand with Bee right before he gets up, flicks Frenzy, and beats Barricade up hard enough that he just retreats, as he is known to. Bee doesn't pursue him, as he'd rather not face the current Decepticon line-up on Earth single-handedly. In order to protect Hailee, he leaves, emotional goodbye, etc...but the pre/mid/post credit scene could show Barricade reporting to Starscream and possibly a few nameless genericons (like with Africa in DotM), telling them of the knowledge acquired from Bumblebee, and have a bit of Decepticon banter (Starscream sounding unwilling to resurrect Megatron, Starscream grilling Barry and stating that other Autobots may come 'soon'), and Starscream contacting Decepticons across the world to begin a search, which could include him sidelining the TF5 guys, for a nice Easter egg. What do you all think?
