Can the Negative Ion of Oxygen be an Oxidizer?

[zalo]

This is just a little question to satisfy my own curiosity, but can the Negative Ion of an Oxygen atom/molecule be used as an oxidizer?
I would think not, because it wouldn't be able to accept another electron if it already has one. Am I right?

The singly negative ion of oxygen (O^-) is a relatively powerful oxidizer. The doubly negative ion (O^2-) is not. (read: there are virtually no O^3- compounds)

Thanks for the reply, also could the O^2- be used as an oxidizer at all?
