Meet Sheffield O'Callaghan! The uncle of Morgan who will act as the deuteragonist of their series concept.

In his younger years he was the sidekick and son of a world-famous British archeologist known as Brannon O'Callaghan, whom often embarked on globetrotting escapades alongside two other men serving under the alliance known as "The O'Callaghan Clan".

Originally recognized as an attentive and resourceful boy adventurer, Sheffield has now resorted to only being known as a balding bellyaching 43 year old janitor at the museum he and his nephew normally work at, but sooner or later his former position in life shall be revived, just not exactly as how it used to be.

Though many times he comes off as outspoken, overconfident, and mildly pretentious which is what Morgan usually has to keep in-check whenever they're out and about, Sheffield still has genuine decency in him and will always follow the memo of a plan whenever he and his crew are working with those of higher authority.

Besides his role in the concept intended to echo that of Captain Haddock from The Adventures of Tintin, his personality and design was also influenced by Pops Racer and the late Louie Anderson's father, Andy Anderson.

Special thanks goes to my friend Golkeyx once again for the digitally colored profile artwork of Sheffield.
