Transformers: Rise of the Beasts

It's a recurring thing across most of the Transformers brand, characters are thrown in because they have a toy to sell and will demand characters be removed if the toy is cancelled or not doing well. Beast Wars was far from exempt, but the CGI novelty meant it would cost too much to build a bigger cast. Tigatron, Airazor, Scorponok and Terrorsaur were all removed they were outdated toys and they wanted room for new characters. The writers were quoted as saying because of this they ended each season with the attitude of "Everyone is about to die, let Hasbro sort it out." Bumblebee was the one movie that wasn't backed by a major toyline and thus they had a lot more freedom on actually choosing the characters to have in the story. The 07 movie was also much better for that restraint. Every movie since has suffered in some way by excessive characters standing around to promote a toy. It's why TF Wiki has the page "To Sell Toys," writers and directors can squeeze some creativity on the side but they are not really in control.

Given Rise of the Beasts was giving the Sequel Hook of a GI Joe crossover—presumably with Snake Eyes being the one canon film, that'll have a lot of opportunities to garner interest through both advertising and merchandising for sure.

I'm surprised that they are making the G.I. Joe crossover with Transformers. I wonder how the relationship between the characters would be like?

Hopefully its in the vain of World's Finest and not Dawn of Justice.
