Biggest win: Although he holds impressive first round knockout wins over former champion Benson Henderson and Donald Cerrone, undoubtedly his biggest win came against Anthony Pettis to win the strap.
RDA was an underdog against Showtime and not only usurped his throne, but completely dominated him over five rounds to earn a lopsided decision victory.
His outstanding performance saw him became just the second challenger in UFC history win the title with all three judges scoring it 50-45 in his favour. Randy Couture was the first, achieving the same feat against Tim Sylvia at UFC 68.
Last defeat: Khabib Nurmagomedov at UFC on Fox 11, April 19, 2014. The Dagestani improved his pristine record to 22-0 (6-0 UFC) with his dominant decision victory over RDA. However, he has yet to return to the Octagon since defeating the Brazilian due to a string of injuries, including a recurring knee problem.
Other notable losses include the submission to Guida, decision losses to Gleison Tibau and Tyson Griffin and a thunderous knockout defeat to Jeremy Stephens in his promotional debut.
He has a titanium chin... no really!
Guida broke his jaw in the first round of their clash, forcing him to get titanium plates inserted into his jaw. RDA made the outlandish claim to MMA Junkie that it has given him the ability to break hands by eating punches.
Respected orthopaedic surgeon Dr Johnny Benjamin subsequently told the site that this perceived ability was "absolute fantasy" and added that the titanium in his face is “measured in millimetres, it’s so small.”"That break happened when we were openly trading during the first minute of our fight. He broke my mandible in two parts, but I kept on fighting."
"Nowadays, I have 20 screws and four titanium plates. Since then I broke two hands with my chin: (Gleison) Tibau's and (Anthony) Njokuani's."
He has the Almighty on his side
Judging by his post-fight interviews, RDA is a devout Christian. The lightweight champion usually thanks the Christian saviour Jesus Christ in his post-fight speeches, and the man himself was even in the crowd for UFC 185.
JC was seen congratulating the dos Anjos as he left the Octagon after he became the undisputed champion of the 155 lb division.
