Who is Agent O?

The vector Agent O looking around, glance by glance.

It is the O from the Prover wordmark: two blue halves, dark on the left and light on the right.

The orange visor is a small screen. It shows eyes, a progress bar, a tick or a battery. Short legs and arms pop out when it needs them.
