Transformers Cloud is a Japanese toyline that started in 2014 with the Decepticons are exclusives to e-Hobby while the Autobots are exclusives to TakaraTomy Mall. Main title of the series are called Spacetime World:Guardians Of Time (GOT).
Each Cloud releases comes with a comic book, starting with TFC-A01 (Optimus Prime), TFC-D01 (Megatron), TFC-A02 (Brawn), TFC-D02 (Starscream), TFC-A03 (Hot Rodimus), TFC-D03 (Shockwave) and soon to be release in March, TFC-A04 (Roadbuster) and TFC-D04 (Hellwarp).
The story began with multiple universes existing as product of the mysterious omnipotent being, the Creator. Realizing that all the universes needed order, the Creator selected a universe called "Cloud World" and dispatched an emissary, SARA to guide the inhabitants keeping the peace across the multiverse.

As part of the task, SARA can open dimensional gates allowing the Transformers to travel all across the multiverse and asking in return, for them to gather surplus energy from various sources in different universes. Cloud World Autobots are seen to travel in various other continuity for that purpose, like 33rd HM Spacetime (which refers to the 33rd episode of The Headmasters, Duel on the Asterois) and 24th BW Spacetime (refers to 24th episode of Beast Wars) where both episode involves significant energy surges.
As of now, I've owned 4 Cloud releases which are TFC-A01 (Optimus Prime), TFC-D02 (Starscream), TFC-A03 (Hot Rodimus) and TFC-D03 (Shockwave) as only these 4 out of 6 uses original CHRUG mold, plus the upcoming TFC-A04 (Roadbuster) and TFC-D04 (Hellwarp).

Hot Rod was first introduced in The Transformers : The Movie (1986) as a young Autobot stationed in Autobot City. He was the first to suspect something is wrong after Daniel pointed out a hole on the Autobot Ship while they're fishing (yes, fishing). He was present during Optimus Prime's dying moment after bravely fighting Megatron (many would argue Hot Rod's interference in the fight was the cause of Optimus Prime's death but I personally think Megatron would've done the same with him being close to the gun) and caught the Matrix when it was being passed to Ultra Magnus (which many would also argue that it's the reason why Magnus can't open it during an attack afterwards. To me, it's been decided by the Matrix beforehand)
During the battle against Galvatron inside of Unicron, Hot Rod was overpowered by the new leader of the Decepticons before he manage to tap into the power of the Matrix with the most epic soundtrack playing at the background.
|Arise, Rodimus Prime!|
Transformers Cloud series comes with a box with character artwork on the front, in this case Hot Rodimus. The artwork combines with its pair with the Autobot character facing towards the right and the Decepticon (in this case, Shockwave) facing towards the left.
