IS ALL LOST?! The evil Sigma unleashes an unstoppable army in "Worlds Unite" Part Eight: Sonic, Mega Man and X lead the unified army against Sigma’s horde of resurrected Mavericks! Sigma has now taken command of the Genesis Portals, threatening to fuse together even MORE worlds! With our heroes’ time and strength running out, Sticks returns with reinforcements—and you’ll never believe who she recruited! Featuring cover art from the legendary Patrick "SPAZ" Spaziante, and variant cover art from Sonic rising star Diana Skelly and part 8 of the epic 12-part connecting variant cover series by artist Ben Bates!
The evil Sigma unleashes an unstoppable army of resurrected Mavericks, and although tired and injured, the unified army led by Sonic, Mega Man and X must fight against them. Axl is disturbed by the reappearance of his old Red Alert foes, but X assures him it's better that they rest in peace. X then meets with Zero, who is grateful that Colonel and Iris aren't among them. Wily and Eggman attempt to help with their cannon, only to have it destroyed by Tornado Tonion before they are saved by their arch-enemies.
With the heroes nearly beaten, Sigma opens multiple Genesis Portals and prepares to fuse together more worlds, sending Mavericks with Unity Engines to each of them, leaving behind Vanishing Gungaroo, Burn Rooster, Dynamo and Double to finish them off. With time running out, Sticks returns with reinforcements from the World of Street Fighter: Chun-Li, Ryu, Ken and Guile. The Street Fighter cast quickly turns the tables and defeats the Mavericks. Seeing this, Sally comes up with a plan: recruit heroes from multiple worlds to help stop Sigma. Eggman wants a back-up plan, but it turns out that between him and the Freedom Fighters, all seven Chaos Emeralds have been gathered.
With Sigma ignoring the heroes due to his belief in his overwhelming power, some of the cast agrees to stay behind and guard the Emeralds while the others head through the Genesis Portals and recruit who they can. Wily and Eggman, however, finally see their chance at reaching the Master Engine and acquiring all that power for themselves. As they prepare to concoct a plan, Xander Payne warps them straight into the heart of the Lost Hex, putting them with distance of the engine with the good guys none the wiser.
One of the readers is reading the latest issue of Worlds Unite, comments how exciting it is, and wishes to be a part of it. Comedy Chimp tells him to trade places with him and Fastidious Beaver and tell the writer to take them home, as they run away from Sigma.
- Sonic: If you had a diabolical back-stabbing plan, now might be a good time to redirect it at these guys!
- Dr. Eggman: I...I don't!
- Sonic: How can you be out of ideas?! I thought you had the "master plan"!
- Dr. Eggman: You're the one who always saves the day! What's your excuse? Run out of "fast"?!
- Sticks: Da-da-da-daaaaa! Presenting the new and improved Team Sticks! NOW LET'S GET 'EM!!!
- Chun-Li: Spinning Bird-Kick!
- Sally (amazed): Wow!
- Ken: Shoryuken!
- Knuckles (also amazed): I gotta try that!
- Ryu: Hadouken!
- Mega Man (looks at his Mega Buster): ...Huh.
- Guile: Sonic Boom! (Sonic gives an unimpressed look)
- Ken: Haha--it's like we've stepping into a kids' cartoon or something.
- Ryu: It's certainly...odd.
- Sonic: Happy hunting, guys! You'd better bring back somebody cool!
- Mega Man: Haha! You too! (To Amy) He never gives up, does he?
- Amy: Never! And you've kept pace with him this entire time--you're just as impressive!
- Mega Man: Aww...thanks!
- Dr. Wily: Let Mega Man and the others do all the fighting for us!
- Dr. Eggman: Let Super Sonic bounce uselessly against Sigma's armor!
- Dr. Wily: We'll find the Master Engine while they're all distracted...
- Dr. Eggman: ...And harness its power for ourselves!
- Both: And then our geniuses will rule all of creation!
- During a battle between the heroes and the Maverick army, Sigma uses some Genesis Portals to send the army to other worlds to activate more Unity Engines, while leaving the Mavericks Double, Dynamo, Vanishing Gungaroo and Burn Rooster to finish off the heroes.
- Straight from her visit to the world of Street Fighter, Sticks brings Ryu, Ken Masters, Chun-Li and Guile, and the four world warriors defeat the four Mavericks.
- The heroes head into the Genesis Portals to recruit heroes from other worlds to help out.
- The evil doctors and Xander Payne secretly infiltrate the Lost Hex and begin enacting their plan to double-cross the heroes.
- The line on the first variant cover, "Bald Is Beautiful", is a nod to the number of bald major characters in the crossover.
- When Xander was last seen, he was wearing his orange jail uniform, but in this issue, he is wearing his normal Emerald Spears outfit. How he did so is unknown.
- Despite appearing in the second variant cover, Princess Prin-Prin (from the "Ghosts 'n Goblins series) is nowhere to be seen in the crossover.
