4154. Speedy

Speedy is the sidekick to Green Arrow and a member of Team Arrow. Originally Speedy was Roy Harper, the legal ward of Oliver Queen. As a young super-hero, he fights crime using martial arts and trick arrows. Eventually he would out-grow this position and graduate to calling himself Arsenal, then later Red Arrow. He was a member of the Teen Titans in his youth. Roy Harper was created by Mort Weisinger and Paul Norris, first appearing in More Fun Comics #73. (1941)
Mia Dearden is the second and current Speedy. She is a young girl adopted by Oliver Queen who rescued her from a life on the streets as a prostitute. Mia Dearden was created by Kevin Smith and Phil Hester, first appearing in Green Arrow (Volume 3) #2. (2001)

Mia Dearden was introduced in Green Arrow (Vol. 3) #2 in 2001. Mia was a teenaged girl who ran from her home after being abused by her father and fell into child prostitution. Mia was rescued from one of her clients by Oliver Queen, who had just recently returned from the dead. Mia continued to try to convince Oliver, who was busy trying to reconstruct his own life, and began to secretly train with Connor Hawke in archery and combat. Mia continually petitioned Green Arrow to allow her to serve as his sidekick, but Oliver continually demurred, not wanting to put another youngster at risk. Mia redoubled her efforts and Green Arrow finally allowed her to become the new Speedy. Shortly thereafter, she joined the Teen Titans but has since left the team.

Speedy (like his/her mentor) has a wide variety of trick arrows. Most famously his punching glove arrow which is capable of knocking out villains. Speedy also has several other arrows ranging from sleeping gas arrows, exploding arrows, and regular arrows.
Along with his excellent archery skills, Speedy has mastered several different types of hand to hand combat including judo, kickboxing, and karate.
As Arsenal, Roy Harper displayed proficiency with a greater range of weapons, such as guns, truncheons, and boomerangs. He also became a master of Moo Gi Gong, allowing him to use virtually any handheld object as a makeshift weapon.
Roy Harper can speak Japanese[1] and can understand Russian.
