Admiral Joshua Wardell Underwood, Chief of Starfleet Operations (born June 5, 1987, in Sacramento, California, Earth) is a character who appeared briefly as an extra on the fan series Star Trek: Hidden Frontier. This was Joshua Underwood's first (and last) appearance in HF, which he has been waiting for since 2001 after being promised one by the series' creator (and good friend), Rob Caves. Admiral Underwood will appear in the episode "Its Hour Come Round At Last", the series finale. This is a modification of the past history of the character to fit with the Hidden Frontier canon.
