I thought Omar said the boss isn't really "evil" or a bad person. If it's really Negativitron it would mean Sackboy is coming from before the 2nd game or before the end of that game if he's in the Paris level. It's interesting but I wonder why.
also it's probably already been mentioned but negativatron doesnt scream ps1 era or fan of playstation. lots of folks havent even gotten to the end of lbp2 (which i highly recommend ya'll do!!)
THIS IS ACE
Just look at this GIF for proof, he's in the Paris level already!
how can he be a boss when he is featured in a stage as a hazard?
