The Dagda is commonly known to be a bit clumsy looking or acting, but very generous and good. He wears a tunic that is a bit too short that exposes his rump and large member that drags on the ground. He possess several magical objects as the Gods often do. Among these are:
- Undry, a large cauldron that provides an endless supply of food
- a large club that could kill nine men with one end, and restore life with the other end
- Daurdable, a harp made of oak that when played would change the seasons
- Two pigs, one continually roasting, the other continually growing
- Trees that constantly produced fruit
The Dagda is the father (unknown mothers) of Brighid, Breg, Bo Dearg, Aine, Cermait, Midir, and of course Oengus. He may be brother to Oghma and Lir. The Dagda ruled the Tuatha de Danana for a very long time (after Lugh).
