The beast pretenders could have mould mates in existing BW characters. Chainclaw/Polar Claw, Snarler/Razorbeast, Carnivac/Wolfang or K-9 and Catilla/Tigatron. The main flaw of this idea is that pretenders that didn't have animal or monster modes are left behind. That's why I'm of multiple minds about pretenders. It's my favourite G1 subgroup and I would dearly like to see just one done properly with modern engineering but... I'm not sure about a full line or even a large portion of a line dedicated to pretenders because of not being sure how they'd work under modern price point/size class constraints. So given that they're intending to more or less keep legacy gimmicks for characters they revisit at least for the WFC lines (Spinister admittedly doesn't come with his two small targetmasters) I'm kinda leaning towards there being at most just a few pretenders in the future. Two, maybe, to get the most out of a single mould. Likely none because they've got a good chunk of G1 characters to redo until WFC is over, at which point they gotta start on OP and Grimlock etc all over again. So pretender characters being thrown in alongside BW stuff is "fine, okay, it's decent" with me overall.
