Worlds Collide is a Mega Man and Sonic the Hedgehog crossover by Archie Comics.
Here is a concept of what I think it would be like a game.
Gameplay
The gameplay and graphics are mainly based on Mega Man 10 and Sonic Mania (if 2D) or Mega Man 11 and Sonic Generations (if 3D), with elements from Mega Man Powered Up, Sonic Battle, and Sonic Rivals 2, like having several characters available and extra modes.
Most Mega Man playable characters and bosses have 24 HP instead of the usual 28. The Robot Masters from Skull Egg Zone 3 have 12 HP.
Sonic characters don't lose all rings when hit (similar to Sonic Triple Trouble). Instead, they lose 10 rings for each point of damage, with half disappearing after they fall from the character.
Stages
Main mode
At first only Mega Man and Sonic are available, and they are the only ones with a major story. Other characters can be used, but some stages may change depending of the character:
- The Opening Stage is character specific.
- The 2nd and 3rd stages may switch depending of the character, with Green Hill Zone for Sonic characters and Mega City for Mega Man characters, but the boss order remains the same. The stage order is the same for Mega Man, Proto Man, Sonic, and Tails.
- When playing as a character that also appeared as a boss, other character will appear in his place. For example, Bass and Metal Sonic will face Mega Man and Sonic.
- The Skull Egg Zone 1 and 2 varies depending of the character, Zone 1 having a total of 4 versions (2 for Mega Man and 2 for Sonic characters) and Zone 2 having 10 versions (5 for each series). Zone 3 is the same for all.
- Wily Egg Zone 2 has 4 versions, 2 for each series. Also, Duo has an unique version of the Wily Egg Zone 1, and he skips Zone 2.
- The final stage, Super Genesis Wave, is exclusive to Super Armor Mega Man and Super Sonic in the main mode, but other characters can access it in the extra modes (like Time AttacK) after clearing the game with Mega Man and Sonic.
- When using Mega Man characters, they will use Item-2 (with its energy depleting), except Duo as he can fly, and Bass in his Super Bass form.
- Most Sonic characters will be in super states (Super Tails, Super Knuckles, Super Shadow, Super Silver, and Burning Blaze), while the others will be carried by Tails with the Tornado.
- Except for super state characters, Super Armor Mega Man and Super Sonic will appear in the background when using other characters, suggesting that they are protecting them from the effects of the Super Genesis Wave. However, the battle may be harder for non-super state characters, and might be impossible for Guts Man (no blocks) and Oil Man.
The player starts in a stage select area similar to Sonic Generations and Sonic Advance 3, but a bit smaller, although not as small as the game selection from Mega Man Anniversary Collection.
| Stage | Name | Boss(es) | Details |
|---|---|---|---|
| 1 | Opening Stage | ? | A short, character specific tutorial stage focused on story and introducing the character. |
| 2 | Green Hill Zone | Mega Man (Sonic characters) Sonic (Mega Man characters) |
|
| 3 | Mega City | Tails Man | Tails is unlocked after completing the stage, and Mega Man gains his first weapon and Rush. |
| 4 | Dr. Light's Lab | Bass (Sonic characters) Metal Sonic (Mega Man characters) |
Very short stage focused on story (or just story, may not be a stage?) with a brief battle (like Mega Man 7). Shop become available and Proto Man is unlocked. |
| 5 | Skull Egg Zone 1 | Copy Robot, Genesis Unit, and Roboticized Masters (Chaotix) | Copy Robot skin and Chaotix are unlocked after clearing. |
| 6 | Skull Egg Zone 2 | Roboticized Masters (part 2) and Shadow Man | Most of Sonic's friends are unlocked after clearing the stage. |
| 7 | Skull Egg Zone 3 | Rouge Woman | Instead of enemies, this stage is filled with Robot Masters. The player must defeat 16 Robot Masters (selected randomly, but there is a higher chance for specific ones to appear depending of the player's character, listed below) and Rouge Woman to continue. Note that while the Robot Masters have lower HP compared to normal bosses, Rouge Woman has normal boss HP. Rouge and Omega are unlocked after clearing. |
| 8 | Wily Egg Zone 1 | Mega Man Killers and Chaos Devil | The Mega Man Killers are fought one at a time like Mega Man V. |
| 9 | Wily Egg Zone 2 | Bass and Metal Sonic | Checkpoint S to X. Duo is unlocked. |
| 10 | Wily Egg Zone 3 | Wily Egg Machine X | With the arrival of the Light Robot Masters, some heroes go into the fortress to stop the doctors. Dr. Light's eight Robot Masters are unlocked. |
| 11 | Super Genesis Wave | Wily Egg Machine X (Full Power) | Only available for some characters. The final battle. |
Mega mode
An alternate game mode that is similar to the Mega Man games. The stages from the eight bosses are the different versions of the Skull Egg Zone.
| Opening Stage | Tails Man |
| Rose Woman's Stage | Rose Woman |
| Knuckles Man's Stage | Knuckles Man |
| Shadow Man's Stage | Shadow Man (with the other Shadow Man as mid-boss) |
| Silver Man's Stage | Silver Man |
| Blaze Woman's Stage | Blaze Woman |
| Charmy Man's Stage | Charmy Man |
| Espio Man's Stage | Espio Man |
| Vector Man's Stage | Vector Man |
| Wily Egg 1 | Rouge Woman |
| Wily Egg 2 | Chaos Devil |
| Wily Egg 3 | Bass and Metal Sonic |
| Wily Egg 4 | Egg-Wily Machine X |
Extra stages/modes
Any playable character can be used in this mode, otherwise stated.
| ? | Mega Man 10 and Mega Man 11 challenges like hit/take the enemies, targets, balloons, and plates. |
| ? | Chaos Emerald stages? |
| ? | The Roll minigame. Maybe something like the Mean Bean Machine? |
| Challenge | Character specific challenges, like Mega Man Powered Up. Has four challenges for each character. |
| Time Attack | Replay cleared stages and try to clear them as fast as possible. |
| Stage Time Attack | Same as Time Attack, but only the stages, skipping the bosses. Skull Egg Zone 3 and Super Genesis Wave are not available in this mode. |
| Boss Time Attack | Same as Time Attack, but only for bosses and sub-bosses, like Mega Man 11. |
| Boss Rush (Roboticized Masters) | Classic boss rush, with 8 teleporter for the Roboticized Masters (excluding Tails Man and Rouge Woman). |
| Boss Rush (Skull Egg Zone) | Same as previous one, but with other bosses. (Genesis Unit, Mega Man Killers, Chaos Devil, Bass, Metal Sonic, Wily Egg Machine X) Copy Robot is not included in this mode as he is basically a weaker Bass. |
| True Boss Rush | All bosses from the previous Boss Rush modes, and Copy Robot. |
Combined bosses
| Genesis Unit | In the main game you only faced one or two of them, but can you handle the Genesis Unit and Copy Robot at the same time? |
| Mega Man Killers | In the main game you fought against one at a time. How you will fare against their united might? |
| Roboticized Masters | How long can you survive against the combined Roboticized Masters? (Minus Tails Man and Rouge Woman) Or can you defeat all of them? (A survival/time attack stage based on Sonic #249) |
| Roboticized Masters + | Same as the previous one, but with Tails Man and Rouge Woman included to increase the challenge. |
| Robot Masters | Survival mode. Up to 8 random bosses will appear, and when one is defeated, other takes his place. Score is based on time alive and number of bosses defeated. Rouge Woman appears every time 50 bosses are defeated. |
| Ultimate Challenge | Same as Robot Masters, but Copy Robot, Mega Man Killers, and Roboticized Masters (including Rouge Woman) will also appear as random bosses, making this the ultimate survival mode. |
| Nightmare | Unlocked by defeating 300 bosses in Ultimate Challenge. Same as the previous mode, but the game is pushed to the limit by having 16 bosses at the same time, and the Robot Masters have normal HP (24). Also, after every 100 bosses defeated, Bass and Metal Sonic will appear. And if you are badass enough to see it, Chaos Devil will appear after every 500 bosses defeats. |

Robot Masters
All Robot Master from Skull Egg Zone 3. With a few exceptions, they all have about 50% chance to appear, having a higher chance to appear (85%?) for specific characters. Duplicates won't appear, and once a Robot Master is defeated, it won't reappear until 40 Robot Masters are defeated. A Robot Master can be specified to up to five characters. Excluding the few exceptions, once a Robot Master appears 5 times for its speficied characters, its chance to appear will be reduced from 85% to 50% until the player returns to the main menu or reset/quit the game.
Each Robot Master has 12 HP, and their attack damage can't be higher than 4.
