After some thinking, I decided to re-show show some concepts for something that died along with Super Justin.
Back in 2008, Deepercutt released his Youtube Poop "HIT ME!!!", being my first exposure to the One Piece universe, and the following year I suddenly got the idea to remake New Super Mario Bros with Justin (of course) in Mario's place with some Sonic-themed gameplay and speed elements and with harder, Mega Man-styled bosses all powered by Devil Fruits, while Justin was stuck with using traditional Mario-styled powerups which didn't reach the same effects power-wise.
These "Fruited characters" would all replace the encounters against Bowser Jr. and each of the World bosses, fighting with the strategy and skill of a Mega Man boss.
Wile their names of the Fruit Gang above (sans the one on the far left- see below) have been lost in time thanks to the shutdown of the Super Justin Wiki, the Devil Fruits they would've used is still present.
The pixel art shown above was made on February 28th, 2009, a month before I entered the online world). From left to right, this would've been the order the player would've met and fought them:
1-Fortress: Gomu Gomu (Rubber)
1-Castle: Bomu Bomu (Bombs)
2-Fortress: Baku Baku (Eating)
2-Castle: Bane Bane (Spring)
3-Fortress: Toro Toro (Strange liquid, changed to Water in this game)
3-Castle: Chi Chi (Custom Blood-based fruit)
4-Fortress: Beri Beri (Orbs)
4-Castle: Goe Goe (Sound/Voice)
5-Fortress: Shari Shari (Wheels)
5-Castle: Hie Hie (Ice)
6-Fortress: Kochi Kochi (Hardening body parts)
6-Fortress 2: Toge Toge (Needle/Spikes)
6-Castle: Mera Mera (Fire) (related to Goro user)
7-Fortress: Supa Supa (Blades in limbs)
7-Castle: Goro Goro (Electric) (related to Mera user)
8-Fortress: Horo Horo (Ghosts)
(Anything beyond would've used the game's more major villains, who aren't powered by fruits)
Below are artworks that accompanied the drawing of the pixel art of the characters above, which are both as of now seven years old. By then my knowledge of One Piece itself was only a year old and when the seven-character group was drawn (on May 11, 2009), it wouldn't be until five months later when I would give the series le boot and put Zora in it's place.
In-between the two artworks, the Gomu Gomu no Mi user also got individual artwork of his own, on May 1st. He is the only one with his name still known: Hota. (Which ironically stands for "Firefly", nothing in relation to his rubber-themed powers.)
Do not take this as a sign that these characters may return in some way (and if they do, don't expect them to be put into Aozora or any other actual "series" for that matter). They're far enough away from Super Justin that there should be no problem showing them off. Especially since I feel like I could do a "Draw this Better" scenario to show how different the characters would look in this age after seven years of absence.
