A sea of yellow, with it all being released within the first two waves of each size class... AND the photo is still missing the 2 Kreons, the Kreo car, the 6-inch Titan and the Hero Masher. (the last two I don't yet have)



Just to offset it a little, here's Optimus after the same amount of time, and also missing the same items as Bumblebee.
Just like with Rescue Bots, a character with just a couple of cameo appearances almost has the most amount of toys of all the characters.


Some of the other characters who have the most toys...




Everything I have so far for RID, except the Kreo (on another display case) and the Super sized Bumblebee (on the top of the display case).


The Kreo shelf...
