Worf possesses an incredibly in-depth Memory Alpha Wiki Page detailing everything from chronology and notable moments of character development, all the way to physical properties (apparently he has a peaty smell, possibly with a hint of lilac.)

At the point in canon I am taking him from (2375, season 7 of DS9) Worf is 35 years old. As a klingon, he has dark skin and prominent ridges along his forehead with long, crimped brown hair kept in a tight braid. He bears immaculately kept facial hair. He is generally stoic and unyielding in his expression, sometimes fearsome, and very rarely smiles. He is quite tall and is well-built from regular training (both in Mok'bara meditation and more active holodeck fighting, unarmed and with a range of melee weapons.) As an ambassador of Qo'noS, Worf is more often wearing traditional Klingon garb for the position, however it has been shown that he is quite willing to exchange this ceremonial costuming for his much more familiar Starfleet uniform when needed.

Worf is a forbidding, unrelenting sort of person, giving no leeway for jokes or humour -- in truth, he does possess a subtle sense of humour, but he rarely tolerates that of others, being easily annoyed by jokes at his expense. He appreciates honesty, loyalty, bravery and strict self control, but he also appreciates fierceness and fearlessness. He walks a delicate line between his Federation upbringing and his intense draw to traditional Empire values. Above all he believes himself to be a just warrior, and time with its many trials has tempered him to better appreciate where his two opposing sets of values intersect. He is by no means able to balance all of these factors perfectly in every situation, but he tries. He errs on the side of conservative belief in tradition and attempts to bring these values into his daily life and the lives of his friends. Some would see him as stubborn and occasionally obstreperous, but it is his strict conformation to his beliefs that has allowed him to survive near fatal physical maladies, social pariahism, personal letdowns, and trials of resolve year after year, and not only to survive, but to guide others through dark times with unwavering determination.
