According to the "Death Tales of the Tuatha de Danaan", Aengus killed his step father Elcmar for killing Midir.
Aengus also slew the poet of Lugh Lamfada for lying about his brother Ogma an Cermait. The poet claimed that Ogma was having an affair with one of Lugh's wives. Aengus killed the poet in front of Midir.
In "The Wooing of Etain," Aengus was able to partially lift Fuamnach's spell against Etain, the horse goddess he had won for his brother Midir. Fuamnach in a jealous rage had turned the girl into a butterfly. Turning her into a woman at night, Aengus made her his lover until Fuamnach found out about it and drove her away.
Four bright birds that ever hovered about his head were supposed to be his kisses taking shape in this lovely form, and at their singing love came springing up in the hearts of youths and maidens.
In the "Tale of the Two Pails," a sidhe woman and foster daughter of Aengus gets lost and winds up in the company of St. Patrick. The girl converts to Christianity, and Aengus can not win her back. He leaves, and she dies of grief a few weeks later.
