Coletti

Coletti was a 23rd century Human man who served Starfleet as an engineering ensign, assigned to Federation starship USS Enterprise (NCC-1701-A) in the 2280s.

Coletti served under Montgomery Scott shortly after James T. Kirk and his crew were assigned to the Enterprise-A, helping him make the new ship's systems functional. Coletti also helped Scott cure the humpback whales George and Gracie of a mysterious illness they had contracted after arriving in the 23rd century. (SS TOS (Scotty's Song))
