Looks like we have a tie between DC Nation and Yo Joe. I was an 80's kid so I'll have to cast the tie breaker in favor of Yo Joe! Here is the next batch. Big thanks to Patraw for contributing half of this list!
#1 Bling Thing
This competition is all about the Benjamins! There are three different approaches you can take to this challenge:
1) Customize any character who's typically depicted as being filthy rich. Tony Stark, Lex Luthor, Uncle Scrooge McDuck, Ritchie Rich, Uncle Pennybags, etc.
2) Craft a figure that's literally made out of money or some other expensive/precious material. Stuff like Nugget from Rock Lords (gold), Swamp Thing with a body made out of dollar bills (something he actually did in an issue of Hellraiser one time), etc.
3) "Pimp" out any character with "bling". Put so many gold chains around Deadpool's neck that he can't move, cover Optimus Prime's chassis with faux diamonds, etc. Basically pretend the character has more money than common sense and load them up with expensive and gaudy accessories.
This challenge focuses on characters that can temporarily join with others to create super/deluxe figures. We're talking about Combiners/Gestalts like Bruticus, Puzzler, Interlink Spawn, Lion/Vehicle Voltron, Power Rangers Megazords, etc.
- To make life easier, you don't have to make all the components of the Gestalt, unless you really want to (i.e., nobody expects you to customize all six G1 Constructicons for a single entry). Instead, you can simply make one member/unit of the combiner team - OR - craft a custom of the completed Gestalt that doesn't come apart. In other words, continuing with the Constructicons example, you could just make Long Haul by himself or a stand-alone Devastator figure.
The goal of this contest is to make a custom of those toys that, for whatever reason (bad sculpt/paint, poor design, obscure character/property, heavily case-packed, controversial/dangerous, etc.), were hideously unpopular and remained on store shelves/pegs for months, even after being heavily discounted. Stuff like Dee-Jay (G1 G.I.JOE), Pruneface (Kenner Star Wars), Gore (Total Chaos Series 1 - so bad that McFarlane replaced him with the Conqueror in the 2nd edition repaints), etc. Of course, this being a custom contest, you should attempt to improve on whatever was wrong with the original, so that they'll "sell" this time.
#4 Small Fries
This contest focuses on the small folks. Whether they be children, teens or just small statured adults the important part is they are shorter than the average character. Entries for this contest must be smaller than the scale they are made for. For example contest entries for the 6-inch scale must be 5 inches tall or smaller. Think of people like Damian Wayne, Puck, Antman, Wasp, Gollum, Molly Hayes, Wilykit & Wilykat, Franklin Richards, and Yoda.
..and now for something completely different. The goal of this contest is to tell a story. Instead of using the pictures to show off a custom, we will use them to show a sequence of events and the description area will be used to give context to the pictures. This isn't about creating a long or complicated story, in fact it should be kept simple. Think of things like Spider-man stopping a mugger, Human Torch pulling a prank on the Thing, Batman stopping the Joker, Superman fighting Bizarro, etc. etc. This challenge of this contest is not only how good of a custom can you make, but also how good of a story can you tell with them.
#6 Unreal Estate
This contest is about one thing; Location, location, location. The goal of this contest is to create a place. It can be a scale size set, a diorama of a famous event or a miniaturized landmark. Entries can be large and complicated like the castle from Super Mario 64, Avengers Mansion, JLA Watchtower, the Batcave, Titan's Tower, Daily Bugle Building, Four Freedoms Plaza or the House of Mystery. They can also be a small simple set like a roof top, alley way, street, bank vault, throne room, hideout, weapons locker, etc, etc.
