Alternate reality

Counter was a Starfleet cadet who entered Starfleet Academy in the 2250s.

When Vulcan was attacked by the Narada in 2258, Counter was assigned to the USS Odyssey to assist in the rescue attempts. (Star Trek)

This cadet's fate is unknown, but since the starship they assigned to was destroyed, is is highly likely they perished along with it.
The name Counter (cadet) originated from the source's script. It was otherwise unintelligible on screen. [1]
