Harry Wells (Earth-2: Pre-Crisis)

"You know, when I came to this stupid Earth with its good burgers, I was a stupid man. Lost, angry, blah, blah, blah, and you showed me how to be a better person. And I will always be grateful of this friendship. Now run, Barry, run."

- Harry's final words to The Flash

Harrison "Harry" Wells was a scientist from Earth-2 and the director of S.T.A.R. Labs. After the Singularity happened, he went through a breach to Earth-1 and met Team Flash.

After the Crisis, him along with an infinite number of Harrison Wells were killed and their brainwaves were tangled with Nash Wells', making their consciousnesses reside in Nash's mind.

Early Life
Harrison solved Einstein's riddle at the age of 10.

At some point, Harrison met an unnamed woman and married her. Later, they had a daughter and they both treated her with passion.

In 1991, S.T.A.R. Labs was founded by Harrison, and he was devoted to his work for more than 20 years. However, he was heartbroken after the death of his wife and could not move on.

Creating Metahumans
Unlike his Earth-1 counterpart in the original timeline, he was able to create the particle accelerator in 2014. However, the accelerator exploded, causing numerous people to gain superpowers.

After the accident, Harrison realized the danger of having meta-humans in the city and created a meta-human alert app which gained the attention of the speedster vigilante, The Flash which caused both of them to disagree with each other's perspectives on the accident.

During the Singularity, The Flash was pulled into a wormhole and arrived on Earth-1. Later, he discovered a breach in the basement of S.T.A.R. Labs and travelled to Earth-1.

Meeting Team Flash
After Harrison arrived on Earth-1, he stayed at S.T.A.R. Labs and observed the activities of Team Flash. At a point, he stole an energy rifle and assisted The Flash on defeating Shay Lamden. Later, Barry brought him back to S.T.A.R. Labs and was mistaken as Eobard Thawne.
