First idea: An object that is described in the report as being ridiculously over-the-top, with the entire report written as if by a deranged fanboy of the object. I'll call it SCP-∞
For example, something like:
Class: Hyper Infinite Keter
Special Containment Procedures: You can't contain it, it can escape ANYTHING!
And a test log like:
- Introduced to SCP-682. 682 started wetting itself and crying for its mommy right before it died!
- Put through SCP-914 on Very Fine setting. Came out exactly the same except for a note reading "Sorry, can't improve on this". SCP-914 then exploded.
- Introduced to SCP-343. 343 started worshipping it.
At the end there is an addendum revealing that this SCP is nothing more than a mundane object whose only anomalous property is that anyone that touches it becomes convinced it is the most awesome/powerful/dangerous thing ever, and the initial report was written by someone who had touched it. That researcher was reassigned and the one writing the addendum makes it clear that none of the test logs and such in the original report ever happened.
The second is a description of what seems to be an invisible, intangible, indestructible entity (classified keter), which is contained in a hugely reinforced cell with meters-thick walls of the strongest materials, telekill alloy, etc. There will be details of many failed attempts to measure and destroy it, the entity proving immune to detecting and indestructible every time. In the end there will be a note like:
- Um, guys? I think it's just an empty room.
The third one will be an object (maybe an anvil with an ACME logo on it) that causes anything in its immediate area to operate under "cartoon physics", such as being able to walk past ledges and only fall after looking down, survive falls from great heights and leave body-shaped impressions in the ground, be unharmed by explosives and only get soot on your face, be able to paint a tunnel on a wall and then go through it, etc.
Do any of these sound like they have potential?
