I just found these on the website for the UK Hamleys toystore - wave 2 of the Rescue Bots (Academy) Mini-figures. Just like wave 1, there are 16 different blind-packed figurines, with two molds of each character - Wedge, Hotshot, Medix, Whirl, Hoist, Optimus Prime, Bumblebee, Chase. The five pairs of Academy bots are new molds, while the other three pairs are redecos of three characters in wave 1 (the 2 Bumblebees, Optimus's and Chases). (wave 1 was released in August 2018) This second wave appears to already be in stock, so I'm not sure how long they've been out for. (bigger images on the product page) .
I remember Wave 1, it was one of the first stories I front paged while back in August 2018 New Rescue Bots Blind Bags At Walmart - Transformers News - TFW2005
