Just realized that i left a word out in my last post,they wound up naming a toy after a vibrator called Nexus Maximus.This has caused a lot of shit between Hasbro and parents.
Hasbro has nothing to do with canonical things in the TF universe really,if any toy company did it would be Takara since they actually own the Transformers property,Hasbro only distributes them State side.But as far as cartoons and comics go,there is no real canon per say,most consider the original G1 stuff the main canon,and everything else(besides Beast Wars and Beast Machines,since they happen after G1) as an alternate reality or universe.
When it comes to something like the movie,Hasbro gives Bay and Co ideas for characters,Bay then takes those ideas and revises them,uses who he wants,changes some to other characters or in the case of The Twins,Blackout,and Barricade,he creates his own.Hasbro has no effect in Bay's canonical decision making.
Then comes the comics,Hasbro then consults IDW and Titan Books on what Bay has done,they then take Bay's vision and take it one step further,expanding back into the history of the Movie-verse Cybertron,or actually going into the gap between movies with Reign of Starscream.They say it's canon and want it to be canon,but it's all up to Bay as to what he would consider canon,take Starscream's markings in ROTF,Starscream received them in Alliance,which takes place a few months before ROTF,Bay liked the idea of Starscream having some alien markings and he put them in there,so that was his way of making Starscream's markings canon,but other things have not been made canon.
When it comes to the new Movie-verse,Bay actually holds the cards at this point,all the comics are just filler stuff until that day when the final movie is done and then IDW and Titan Books has the say so in what's canon.
That's what I was trying to get at.
