The game works by scanning a code on the figure, right? So if "Beeside" is a specific character in-game, it means there's a single barcode that is located somewhere on a figure. On top of that, the combos we've seen are "Beeside", "Strongprime". There's not a "Beeprime" or "Sidearm". My guess? The Crash Combiner is two specific figures that are packed together with a single scan code. They likely only work together, hence the "crash". (As a side note, Skyhammer being a crash combiner suggests he's two different people in one) But the "Activators" are going to be midsized Legion/Minicon figures that will be used to combine two standard combiner figures (in this case the standalone Bee, Strongarm, and Sideswipe) That's why they're "Activators". Much like the Minicons before them were "Weaponizers" and before that "Deployers". The Minicon informs the gimmick. Just like Titanmasters are central to the current Generations gimmick. Hasbro has figured out they're more likely to sell if they have direct influence on the mainline.
