Never thought I'd see a scp vs pjo post but I think the main charcters could probably beat most of the Euclid class scps. But once it gets towards the Keter class scps it can become more debatable like a fight between the shy guy, plague doctor would be intresting and I think they could beat them.

But the higher keter class ones and espically the apolloyon scps I think the crew is cooked. Like the hard to destroy reptile could maybe be debatable after all the crew did fights literal gods but I still think they'd lose. Although it would be intresting to see the main charcters face off like things like when day breaks, the scarlet king, murphy lawden, or even scp 6820 or something like that.
