Role in the Books 
Shortly after Lord Voldemort's disappearance, Rodolphus and three other young Death Eaters (his wife, Bellatrix Lestrange, his brother, Rabastan Lestrange, and Barty Crouch Jr.) attacked Aurors Frank and Alice Longbottom, torturing them using the Cruciatus Curse until both lost most of their mental faculties. All four Death Eaters were sentenced to Azkaban prison.
We only hear about Rodolphus once in this book, when Lucius Malfoy tells Rodolphus to go with Bellatrix Lestrange to find Harry and the Prophecy. From this, we gather that Rodolphus was among the escapees from Azkaban near Christmas time.
Twice, Professor Dumbledore and Harry visit Horace Slughorn's memories of one particular night when Slughorn is meeting with Tom Riddle and his associates. In both memories, Slughorn notes it is eleven o'clock, and says that it is time for the gathered students to head off to bed. He remarks to Avery and Lestrange that an essay is due, and they would be given detention if it is turned in late. Note that we mention this Lestrange here because of the name; however, both Rodolphus and Rabastan were born a generation after Voldemort was at Hogwarts. The Lestrange mentioned would therefore most likely be their father.
Rodolphus is only mentioned once in Deathly Hallows, when Nymphadora Tonks (his niece by marriage) says they injured him during her and Ron's flight to the portkey at the Weasleys' Aunt Muriel's.
If this can be considered a strength, Rodolphus is aware of the Dark Arts, and exhibits a willingness to use them, as seen when he tortures Alice and Frank Longbottom.
Relationships with Other Characters 
As noted above, he is the husband of Bellatrix (née Black). It is mentioned in Harry Potter and the Goblet of Fire that he stood high in the ranks of the Death Eaters during Voldemort's first rise to power.
