"E-Quip" - Autobot Armoured Combination Buildbot.
Apologies for double-dipping, but I bought the two combiners I briefly showed above, took some photos and found some YouTube reviews.
These toys were available at the "Daiso" discount shops in Japan (for ¥500 each). These are the same molds as a version available as a boxed set at Amazon, but with a few paint apps or tampos missing (such as the lack of silver paint of Fire King's cab-gun, the lack of the large symbol and "Titan" text on the back of Titan's cab and lack of faction symbols for all the bots). This could be due to pricing and/or avoiding anything even remotely similar to Autobot/Decepticon symbols in Japan (as it's officially sold by Daiso, who probably don't want Takara-Tomy breathing down their necks).
Also, although each team member has their own assigned number, they also have an additional "Robot Number" (from 9 - 13) which is in a different order to their primary designations ("03 - Fire King" is "Robot 09", for example).
Also, I noticed that the strange word that's printed on all of the robots ("dinba") is probably just "equip" upside-down (with the actual "e" looking like an "a" upside down).
To keep the post short, I'll use spoiler tags for each section.
