Yes and no. 

He is in the game files, Textures, Model & Localization Text.

But he is not setup as a hero yet, so you can't find them in-game yet.

Localization:

Opbot DV8:

Operating an early recon mission, Academy scouts were exceedingly surprised to discover that a promising species of pre-sentients had, within the span of a few generations, gone from huddling in mud hovels to trying their hand at space exploration. Investigating this extraordinary technological leap, the scouts eventually met a battered robot who introduced itself as OPBot DV8. It explained that after drifting through space for quite a bit and subsequently crashing on this planet, it was rescued by the natives. As they were friendly but of limited intellectual reach, OPBot decided to help them "get there faster," and declined to share more details on the process.

another hero that in unimplemented is Bosun Jennifer Rach

Bosun Jennifer Rach:

Rach was part of a pirate band who broke into an Endless research station and were promptly caught by the security systems. A passing Amoeba ship caught their distress signal, but by the time the Amoeba arrived a Dust-enhanced Rach had already freed her team, cracked the research station lock, looted it, and augmented their ship. As the Amoeba were headed to the Academy she decided to go with them, in spite of the pleas of her heartbroken partner, Sego, and her angry boss, Nico the Psycho, who viewed her skills as a ticket to riches. Thanks to her skills with flight technology, she has since made a name for herself as an inventor and test pilot of new and improbable craft and their uses in battle. It is whispered that even though she has the training of the Academy, deep down she still has the heart of a buccaneer…

Ok then. It looks like we can wait for him in the fighters/bombers update. *Still keeps fingers crossed for Vaulters*
