Grodd is a Ferengi merchant, entrepreneur, and thief.
Grodd ran afoul of the ACI in 2409 when he stole several anomalous data samples from the USS Longrifle at Deep Space 9. Hoping to sell them, Grodd traveled with the samples to Deep Space K7 where members of the ACI, including Davin Felth, Skeriss, John McHale, and Jerro confronted him and retrieved the samples for delivery to the researcher Sodock.

In 2413, a team of ACI members encountered Grodd aboard Drozana station and negotiated the transfer of a temporal beacon. The beacon was later used to create a chrono-stasis chamber to house the rapidly aging McHale.
