History:
Dr. Curtis Holt is a bronze medal Olympic athlete and a former employee of Palmer Technologies who worked alongside then-CEO Felicity Smoak in the Design Innovations department. He is the ex-husband of Paul Holt and the boyfriend of Nick Anastas. After learning of Green Arrow's secret identity and the location of the Arrowcave, he joined Team Arrow as maintenance and tech support. While searching for Rene Ramirez to have him join the team, he took a beating from a group of street thugs. This inspired him to be trained and go out on the field, not wanting to feel helpless again. During his first time out, Curtis was jokingly called Mister Fair Play, after his favorite wrestler, Terry Sloane, and for his clean tactics. He was later directly named after Sloane's in-ring name; Mr. Terrific. After discovering that Oliver Queen, John Diggle, and Felicity Smoak respectively had violated his privacy, he left the team, along with Rene and Dinah Drake to formed their own team known as New Team Arrow, until he rejoined Team Arrow to help Oliver battle Diaz, along with Rene and Dinah.

Powers:
 Curtis mentioned that he was a bronze medal Olympic athlete who competed in Beijing. He has shown to keep a regular appearance at his gym and has shown to get his inspiration from pro wrestler Terry Sloane. He has been seen showing his athleticism while evading one of Brie Larvan's robotic bees, chasing down drug dealers and evading attacks from Roy Harper.  Curtis' most prominent feature is his intellect, as he has 14 PhDs, including one in biomedical engineering. Curtis graduated college with a biochemistry degree. He was able to localize the composition of the super-serum that gave Derek Sampson his powers. He led Palmer Technologies' Design Innovations department and was handpicked by Felicity to front the creation of several prototypes for the future. Curtis is also familiar enough with Morse code that he can decipher it without having to look it up.  Curtis Holt is an accomplished engineer, able to invent new forms of technology, such as the T-Spheres and contact lenses with HD displays. He also developed software for tracking certain pieces of technology when the situation demands it, a program he later added to the T-Spheres. He also developed infrared cameras with facial recognition functioning that were later used to identify Andy Diggle. Curtis also assisted Felicity and Cisco Ramon in hacking Dominator technology in order to locate Oliver and company when they were kidnapped. His most noteworthy creation is a bio-stimulant chip that could repair major forms of paralysis.  Curtis is also versed in the field of computer science, has created an algorithm which would improve Palmer Technologies efficiency by calculating the necessary number of layoffs needed to balance the company's budget. He also deciphered Ray Palmer's message hidden in the form of computer static, took over and disarmed Bug-Eyed Bandit's robotic bees, and is often backup computer support and mission control when Felicity is unavailable.  Curtis is capable of fluently speaking 6 languages such as English, French and Russian, though he's noted by Anatoly to have a "horrible" Russian accent while doing so.  Curtis Holt has proven himself to be an amateur fighter when the situation demands it. This is evidenced when the highly trained Roy Harper, an expert street fighter who was trained by Oliver Queen, attacked him and Curtis managed to land two punches on him and evade some of his attacks. Since joining Team Arrow and being trained by Oliver himself, Curtis' combat skills have gradually improved, able to hold his own for a period against a skilled assassin in Scimitar with help from Evelyn Sharp and eventually after more training sessions by Oliver he was able to briefly stand up to Prometheus and both Liza Warner and Carrie Cutter. He has become skilled enough to the point of being able to defeat Nazis from Earth-X with ease. During the Outriders scuffle with Team Arrow, Curtis was able to hold his own against Oliver alongside Rene but was easily overpowered.  Curtis earned a bronze medal in decathlon at the 2008 Olympics.  Curtis is an accomplished BASE jumper.
