UPDATE: More tidbits have been added. Scroll down to see them.
Now that Chaos on Mobius is officially cancelled (and Universal Chaos' 1st Arc is online), I can now reveal some ideas that I've scrapped but have no intention to adapt. For more info on the cancellation, see here: fav.me/dcn2clb
In order that Mel (Sky-The-Echidna
) & I uploaded, here we go...1. Sonic VS Mega Man
During Act 2 of Operation Humanity, Sonic & Rock were going to become close friends during the hedgehog's time of grief. For those who don't remember, Sonic saw Commander Tower kill his mother, only he didn't know that the Tower that killed him was M'egga Man (formerly known as Copy Robot) in disguise. Before the end of the 3rd -and final- Act however, the real Tower was discovered to be a prisoner without anyone knowing... for the Tower that ordered GUN's betrayal against Mobians was Dr Julian Snivley (which explains what happened to him after he failed to help Eggman capture Angel Island and the Master Emerald)! Sonic still didn't know this when he found the real Tower, so he is dead-set on making him pay for killing his mother... but Rock -being aware of the truth- has no choice but to stand in Sonic's way... which leads to a battle reminiscent of Marvel's Captain America: Civil War. After an emotional-and-ferocious fight, Mega Man stops Sonic, but the Blue Blur races out of GUN HQ while saying this to the Freedom Fighters via radio: "Mega Man's not on our side anymore."
BTW, the pic that Mel drew was intended to be a pair of variant covers for Act 3 of Operation Humanity (kinda like variants of certain issues for Archie's Worlds Collide).2. Ra Sky
I wasn't sure when exactly this would take place, but after they started dating, TodStar & Sky got captured by Mogul and his Mephilesologists, and they had a shard of the Ancient Onyx prepared for a ritual involving Sky. Little Planet aligned with Mogul's tower in Empire City, and while the Mephilesologists are chanting and surrounding Sky with the seven Chaos Emeralds, Mogul thrusts the Ancient Onyx shard into Sky's stomach, expelling her Core from her body as a beam of red light shines down on her, which is when black sludge starts appearing over her body. When Sky's eyes are opened, her sky-blue eyes are replaced by a creepy pink pair of eyes that match the shape of the light shining down on Sky... as Little Planet shatters to reveal its true form: Ra Moon (from Mega Man), who now has complete control of Sky's body!
The design of Ra Sky was Ancient Egyptian combined with a futuristic feel... combined with the robot Ra Thor from Mega Man.3. Couple in Mourning
At the start of Operation Humanity's 2nd Act, Sally runs away from Castle Acorn when she learned that the burden of the throne had fallen to her... but she only got as far as the Great Forest, when she found a hooded Sonic, crying in the rain. Despite their own problems, the two of them help each other through each other's pain; Sonic upset about witnessing his mother's death, and Sally mourning her brother's death, as well as becoming Queen of Acorns.4. Birth of Seducia
During Operation Humanity's 2nd Act, Scourge & Fiona got captured by Mephilesologists (Mogul wants Scourge to come back into the cult). In order to capture Sky, Mogul chooses Fiona to be a sacrifice to summon the daughter of Mephiles and (so they claim) Sora the Echidna Goddess. With a sample of Sora's hair shoved into Fiona's mouth and the shard of the Ancient Onyx floating above her as the cult is chanting, Fiona starts feeling incredible pain from her back... eventually an echidna-snake hybrid emerges from Fiona's back, taking the fox's Core with her! And as Seducia fully emerges full of life, Fiona looks completely lifeless (hence the faint colour in her eyes in the pic).5. TodStar + Sky = Galaxy
<- Original concept by Zeusthefox
TodStar manages to throw Sky's Core back into her body, which eventually forces Ra Moon to retreat back to his original form up in space, but Sky is left on the brink of death, and she passes out. TodStar felt like he had to do something, so he tried kissing her... fortunately, the Chaos Emeralds surrounding them not only brought Sky back to life, but it brought her and TodStar closer than ever... literally, because they had merged together to become a being almost as powerful as Super Sonic... Galaxy!
NOTE: One of my rules for fan characters in COM was that no ONE being can match the power of Super Sonic... but when two become one...6. The Destiny of TodSky
Operation Humanity was going to have TodStar and Sky getting to know each other a lot more... but they wouldn't have hooked up until about halfway through the 8th Saga.
Special thanks to Mixedfan8643
for his original take on the mural at the bottom of this pic.7. Friends and Enemies amongst Gods
As was hinted at the start of Operation Humanity, Sora was close with Palutena (from Kid Icarus)... but the Goddess of Light always believed that Sora died... so you can imagine how she felt when she reunited with Sky!
The other pics involve my original take of when the Mephilesologists captured Sky. Instead of Ra Moon, Sky got possessed by Mephiles.8. Bots Helping Bots
Something that happened late in Act 1 of Operation Humanity was that Shadow Android tried to convince Sky that Eggman was evil. During Act 2, he eventually succeeded, but got damaged when he and Sky escaped from the Death Egg (in an attempt similar to The Force Awakens). They were both found by Roll (Mega Man's sister), who healed her and repaired him... Roll even gave him a paint-job and the nickname Shadroid (which is a nickname I've had for Shadow Android for about 10 years). Sky would obviously stick with TodStar, but I don't remember what I was gonna do with Shadroid...
That's all I can think of right now. If anyone has any questions about COM, I'll be happy to answer them.
