Gamma

Gamma (ガンマ) is a giant robot constructed by Dr. Light and Dr. Wily before and during the events of Mega Man 3 for the purpose of peacekeeping and enforcement. During Gamma's construction, Dr. Wily feigned peacefulness, gaining Dr. Light's trust and assistance long enough to complete the robot. Dr. Wily's true intentions were to use the enormous creation as a weapon, furthering his evil plans for world domination.

Strategy
Gamma is the final boss of Mega Man 3. In its first form, it has a small blue head that shoots from its mouth. The simplest way to defeat this form is to stand directly underneath the head and use Shadow Blade. Alternately, the head is also weak to Hard Knuckle. After destroying the small head, Wily completes Gamma's head and controls him, attacking with shots and punches. Gamma's second form is very vulnerable to Top Spin, and can be defeated in seconds by using it rapidly against Wily. If desiring more of a challenge, use the Search Snake.

Trivia

 * Gamma (Γ) is the third letter of the Greek alphabet. He is the first in the Mega Man franchise to have a Greek letter for a name although three other characters, Epsilon (Ε), Sigma (Σ) and Omega (Ω), share the same naming convention.


 * Gamma's small head during its first form seems to have the Greek letter, Gamma (Γ), on its forehead.


 * In Mega Man X5, Sigma's final form is modeled after Gamma, and has a very similar attack pattern, from deadly spiked fists to shooting energy spheres out. In addition, a portion of Gamma's theme can be heard during the fight.
