Dalek Prime Strategist

The  was a veteran Time-Sensitive Dalek drone encountered by the Tenth Doctor when a paradox caused him to land on a version of Skaro which did not remember having fought in the Last Great Time War, but was facing attack from the Hond.

Physical appearance
When the Doctor encountered the Strategist, he operated a battered and rusted Dalek War Machine casing. He refused to upgrade it for a newer model with flight capabilities, wearing the relic with pride: he repeatedly explained to the Doctor that he viewed its wear and tear as his battle scars.

Origins
The Dalek Prime Strategist once claimed to the Tenth Doctor that he was "older than the Emperor himself", to which the Doctor replayed with a skeptical quip, (COMIC: Defender of the Daleks) in accordance with accounts which portrayed the Golden Emperor as the first-ever Dalek. (COMIC: Genesis of Evil) Melody Malone merely recorded in The Dark Times Times that he had "existed for a very long time", calling him "ancient". (PROSE: The Guide to the Dark Times)

War with the Hond
After the Emperor had recruited the Tenth Doctor to help the Daleks fight the Hond, the Prime Strategist met the Doctor in the Dalek City. He led him to the Vault of Obscenities, which the Strategist was older than even himself. As the two made uneasy conversation, the Prime Strategist saved the Doctor from a creature the Doctor did not glimpse clearly.

Soon, they came across a threatening golem-like creature who growled that "soon the Hond [would] destroy all", who was unharmed when the Prime Strategist immediately opened fire on it. (COMIC: Defender of the Daleks)

In the Time Squad
The Strategist was a member of the Time Squad sent by the Golden Emperor to rectify the divergent timeline and "return the situation to Dalek advantage". He served under the Time Commander, although Melody Malone suspected that as he had served under many Dalek Commanders in his day, his loyalty and obedience to this particular individual was questionable to say the least.
