Gamma

Gamma (ガンマ) is a giant peacemaker robot constructed by Dr. Light and Dr. Wily. During Gamma's construction, Dr. Wily feigned peacefulness, gaining Dr. Light's trust and assistance long enough to complete the big robot. Dr. Wily's true intentions were to use the enormous creation as a weapon, furthering his evil plans for world domination. He is the final boss from Mega Man 3. He is very vunerable to Top Spin, and can be defeated in seconds by using it rapidly. He also appeared in the cartoon Captain N: The Game Master.

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.
 * Sigma's final forms in Mega Man X5 and Mega Man X7 are similar to Gamma.
 * In Mega Man X4 during the cutscene of a duel that place between Sigma and Zero, Sigma mentions a Maverick Hunter named Gamma that was destroyed along with his troops by Zero (The english version of that scene refers to him as "Garma", however). However, the namesakes were most likely coincidental and probably has no connection whatsoever to the Classic-era Gamma.
