There's an online Amazon listing (Canadian, not that we hold that against them) for a Repugnus toy:
https://www.amazon.ca/dp/B0785P78QD
As well as a domestic listing for a Counterpunch toy:
https://www.amazon.com/dp/B077ZBCPDV
Repugnus is listed as being 4.54 kilograms in weight, and a quick cross-check seems to confirm this makes him a Legends-class toy. So, a probable Slash/Cindersaur redeco/remold, in my estimation.
The Counterpunch product, meanwhile, is 10" x 7" x 2.5" in size, which seems to match the measurements of Deluxe-class packaging. My first thought is a redeco of Combiner Wars Wheeljack, but this was already done by the Collector Club Subscription Service last year. It's not completely unheard of for exclusive toys to eventually get similar-but-different retail versions (BotCon Thundercracker/Thrust come to mind), and I'm at a loss to cite a toy that would make a better Counterpunch.
Since 2017 was the last year of the Subscription Service, I guess it's possible Hasbro ended up with some extra Counterpunch toys to unload, and they're offering them through Amazon. I don't know how many Subscription Service toys were typically produced/sold, so I'm not sure how realistic this idea really is.
Zob (kind of wants a toy that can do both Punch and Counterpunch modes, but one step at a time, I suppose...)
