From DYOS Wiki

The Grox are a sociopathic, homicidal, cute n' cuddly race of little mechanical monsters inhabiting the galactic core. Originally from the disappointment game Spore as a main villain race, the Grox were briefly seen as allies of The Hacker, abducting Stylesjl's kids.

The Grox definitely know nothing of anyone named 'Steve'.

A constant state of constipation can be the only explanation for the grumpiness of the Grox.
