Blackarachnia’s not the first female Transformers toy. She’s not even the first in America! The first American female Transformers toy was BotCon 1995’s Nightracer and the first ever anywhere was Japan’s Minerva. (Freezon was released earlier, but her gender wasn’t decided upon until decades later.) Blackarachnia is the first American mass-retail female Transformer, but that’s kind of a lot of qualifiers.
Also some of those silhouettes chosen for use in places seem kind of weird. I’m pretty sure those are Classics Mini-Cons (2006) they use to represent Armada (2002). ROTF Devastator and Fall of Cybertron Slug stand in for their 1985 versions. And I don’t want to try to figure out what that Robots in Disguise silhouette is.
