Wade Eiling

Wade Eiling is a military general involved with the military's metahuman projects.

Early Life
Wade Eiling previously had intentions on doing experiments on Grodd, though Harrison Wells shut down the experiment before they could begin.

Experiments on and hunting Bette Sans Souci
After the S.T.A.R. Labs particle accelerator accident which granted Bette Sans Souci the power of turning ordinary objects into explosives, Wade begun experiments on her, hoping to use her as a weapon in war. After Bette caused an explosion in an office building, Wade decided to take over the case. Wade managed to track Bette and shot Bette though Bette was saved and taken to safety by The Streak. Wade later made it to S.T.A.R. Labs after tracking her location by lacing the bullets with a tracker. Wade was too late as they managed to get Bette out before he arrived. He also had a confrontation with Wells, who denied harbouring Bette. Wade left the crippled scientist alone, reminding that they could've changed the world together.

When Bette supposedly surrendered herself, he and his men were attacked by her with her powers. When Bette was caught off guard, Wade shot and killed Bette. Her DNA turned the bullet into a bomb though Barry rushed her to the river to prevent the city from being hit by the impact. Wade later claimed that the military were only testing explosives and that the city shouldn't be alarmed.

Wade later returned to S.T.A.R. Labs to confront Wells about the Streak. Seeing the potential in metahumans, he suggests that they work together again, to which Wells refused. Wade threatened to bring his soldiers in to take over the building, but Wells countered that he could bring an army of press as well and he could testify against him for his unethical projects. He warns Wade not to threaten him again, or he would end him, and not just his career. Turning to leave, Wade reminds Harrison that he knows his secret and the public will learn it as well.

Hunting Firestorm
Some months later, Eiling detected a nuclear explosion in the badlands outside Central City and ordered his men to retrieve Firestorm. He had an encounter with Barry Allen and the separated Ronnie Raymond at Jitters, and he later abducted Martin Stein. However, following his defeat at the hands of the Flash, he was taken by the Reverse-Flash, who revealed his true identity as Harrison Wells. Wells told him he was a metahuman, and therefore, that he "looked out" for other metahumans, Wells then proceeded to release Grodd on him. It could be assumed that Eiling was killed by Grodd but given Harrison's nature to kill people with knives Wells could possibly be using Grodd to keep Eiling captive. It can also lead to its transformation

Personality
Wade Eiling is shown to be a ruthless man. He will do anything, including inhumane activities to strengthen the US military, even experimenting inhumanely on an animal and even humans, even going as far as to execute them once he was done with them. He does seem to have some respect for Harrison Wells, even calling him the smartest guy that he knows.
