Archon

A classification for SCPs that should not be contained (even though they are capable of being contained) due to the detrimental effects of containment.

The class originated in I.H.Pickman's Proposal, an 001 Proposal. There, the class indicated that containment would have a disastrous impact on the continued survival of humanity. More colloquially, the Archon class originally meant the SCP "will literally break the world if you contain it." The class was later used in SCP-3455 (where it referred to SCPs that are not contained because of the damaging effects of doing so- the more widely used definition and the one I use above), SCP-4200 (an entry in the SCP-4000 contest), SCP-1661 (replacing the SCP's former Euclid classification), SCP-3310 (replacing the SCP's former Hiemal class), SCP-4043, SCP-4494, SCP-4223, SCP-4778, SCP-4634, SCP-5015 (an SCP-5000 entry), SCP-5009 (also a 5000 entry), SCP-4614,SCP-5122, SCP-5520 and SCP-5644.
