The BotCon 2017 boxed set, titled "Action on Hydrus Four", was to have been an Action Master-themed set of Titans Return molds all done up as new Headmaster-gimmicked Action Master characters:
1 -
Actionmaster Optimus Prime (redeco of Voyager class Optimus Prime's body) with
Optimus Prime (redeco of Titan Master Infinitus),
Rad (redeco of Titan Master Diac), and
Lionizer (redeco of Sawback's Titan Master Vehicle lion)
2 -
Actionmaster Skyfall (redeco of Deluxe Highbrow's body) with
Skyfall (redeco of Titan Master Apeface)
3 -
Actionmaster Sprocket (redeco of Deluxe Triggerhappy's body) with

Attack Cruiser (redeco of Brawn's Titan Master Vehicle jeep)
4 -
Actionmaster Megatron (redeco of Leader Six Shot's body) with
Megatron (redeco of Titan Master Nucleon) and
Devastator (redeco of Titan Master Repugnus)
5 -
Actionmaster Gutcruncher (redeco of Voyager Megatron's body) with
Gutcruncher (retool of Titan Master Doomshot/Hazard with a new face) and
Scout Tank (redeco of Terri-Bull's Titan Master Vehicle tank)
The attendee figure for BotCon 2017 was to have been
Dion (redeco of Deluxe Sergeant Kup's body) with
Magnum (redeco of Titan Master Hyperfire)
The souvenirs would have continued the use of Titans Return molds, but as legacy characters from several past series, rather than just Action Masters:
1 -
Doubledealer (redeco of Deluxe Hardhead's body) with
Knok (redeco of Titan Master Nightbeat) and
Skar (a significant retool of Titan Master Sawback with new bat wings, new bat feet, and a brand new face)
2 -
BotCon Heritage Onyx Primal (redeco of Deluxe Mindwipe's body) with
Nightwatch (redeco of Titan Master Infinitus) and swords from TF: Prime Deluxe Wheeljack/Dead End.
3 -
Unicron Trilogy Anniversary Armada Hot Shot (redeco of Deluxe Chromedome's body) with
Alexis Thi Dang (retool of Titan Master Stylor with a new face, the one on display was just Universe Hot Shot's face glued onto the Titan Master) and
Jolt (redeco of Generations Legends class Targetmaster Blazemaster)
4 -
Unicron Trilogy Anniversary Energon Megatron (redeco of Leader Sky Shadow's body) with
Leader-1 (redeco of Titan Master Ptero but with Ominus's face) and sword from Construct-Bots Megatron
5 - Troop Builder souvenir set:
Cassettron Rosanna (redeco of Legends class Rewind),
Cassettron Decepticon Enemy (redeco of Legends class Rumble) and
Cassettron Flipsides (redeco of Legends class Rewind)
One more souvenir set would have been a successor to the Kreon packs, a pack of six Titan Masters done up as Pretenders.
1 -
Pretender Starscream (redeco of Titan Master Crashbash)
2 -
Pretender Jazz (redeco of Titan Master Xort)
3 -
Pretender Bumblebee (redeco of Titan Master Firedrive)
4 -
Pretender Crossblades (redeco of titan Master Diac)
5 -
Pretender Metalhawk (redeco of Titan Master Revolver)
6 -
Pretender Vroom (redeco of Titan Master Grax)
The 2017 customization class figure was to have been
Actionmaster Rumbler (redeco of Deluxe Triggerhappy's body) with
Rumbler (redeco of the Japanese Transformers: Legends Weirdwolf's Headmaster, just like Sprocket) and the
B² Attack Team (two redecos of the Arms Micron B.H., the wrecking ball one that came with Japanese Prime Bulkhead).
As an aside, the name "B² Attack Team" is an in-joke to a very old false BotCon exclusive proposal that Karl Hartman mentioned on the old BotConBeyond.com message board way back around 2000-2001. The fake proposal was for a pair of blue redecos of Beast Wars Retrax called the "Blue Balls Attack Team". So to see these realized here is pretty remarkable.
The three Other Concepts likewise made use of Titans Returns molds as legacy characters:
1 -
Armada Jetfire (redeco of Voyager Sentinel Prime/Astrotrain's body) with
Comettor (redeco of Titan Master Apeface)
2 -
Devcon (redeco of Deluxe Brainstorm's body) with
Slizardo (redeco of Titan Master Hyperfire)
3 -
Turbomaster (redeco of Deluxe Highbrow's body) with
Take Off (redeco of Titan Master Blowpipe)
Finally, the remaining Transformers/G.I. Joe "Only Human" figures would have been:
1 -
Only Human Autobot Springer with Newtronium Munitions Case that converts into artillery platform
2 -
Only Human Ultra Magnus with Missile Stack & Jack Armor (LOL!)
3 -
Only Human Victor Drath
Now, while all of these mock-ups were one-of-a-kind pieces, there was a single piece of merchandise that was mass produced and given away at the (Robocon) con as an exclusive to registered attendees with blue namebadges: A lithograph of the "Action on Hydrus Four" art, by Robby Musso and Josh Perez.
