Eric Myers

Eric Myers is the Quantum Ranger, the Sixth Ranger of the the Power Rangers Time Force

Early Life
Eric attended the same private school as Wes Collins (The Red Time Force Ranger). Whereas Wes came from a rich family, Eric worked hard and was dirt poor, and eventually decided to leave the school, saying he had "bigger plans". Eric was resentful for having to work so hard while Wes did not have to work at all. From this, Eric grew bitter and had few friends.

Life as a Silver Guardian
Eric was first seen as a soldier working for the Silver Guardians, an organization established by Mr. Collins Wes's Father in order to protect the Silver Hills from the mutants.

Becoming the Quantum Ranger
After discovering that Wes was the Red Time Force Ranger, Eric attempted to find his own powers. He became aware that the Time Force Power Rangers are looking for the Quantum powers, and he got to it first and forcibly became the Quantum Time Force Ranger, much to the displeasure of Wes' teammates. Eric then entered a 3-way struggle with the other Rangers and Ransik to grab control of the Q-Rex, and he prevailed, assuming control of the most powerful Zord in the Time Force arsenal.

Life as a Power Ranger
Eric became a reluctant ally to the regular Rangers, remaining separate and occasionally aiding them at certain times. During the end of the series, Eric was wounded by a blast from a Cyclobot, and he handed his morpher over to Wes to use the Q-Rex. Wes was able to use the Quantum Defender and Q-Rex to great effect thanks to this. He recovered, though, turning over a new leaf, establishing friendships and turning from anti-hero to hero. When the Rangers departed for the future, Mr. Collins offered Wes command of the Silver Guardians, who would now protect the city from evil for free and Wes accepted on the condition that a surprised Eric be his partner.
