Format:

Me: I think a brick can kill it.

You: (failure, or success) and a couple of paragraphs why.
Then you suggest a new way to kill him.

To overcome literary barrier:
To kill him, you must destroy 99% of his body down to a cellular level.

Scp 173 once decapitated SCP 682. But it grew a new head and gained many eyes.

Scp 096 was enraged and started assaulting SCP 682
After hours of screaming no damage was done on 682

Scp 079 and SCP 999 are the only friends of 682

No, what you need to do is suggest something you think MIGHT kill him. The next person writes if that succeeded, why, and postulates another thing that might do it.

well you take it and fine a nice star that will go hypernova in a few million years and leave it next to it or find a black hole and throw it in.
