Daredevil #162 Jan 1980
"Requiem for a Pug!"
After absorbing a large amount of radiation while stopping a malfunctioning meson reactor,
Daredevil passes out and comes to with amnesia. He doesn't know who he is, but quickly realizes
his special powers and instinctively uses them to fight some criminals while in his street clothes,

drawing the attention of a crooked boxing promoter, Mr.Hyle, who takes him in to turn him
into a prizefighter. When he refuses to throw a fight and his trainer takes a bullet for it,

DD regains his memories and takes out Hyle, his goons, and his pet leopard.
