Dr. Carl Tanner was the former partner of Tina McGee and her husband David. He later became an enemy of the Flash.

Biography

Carl had lived a life in poverty, faking wealth in order to get into the scientific community.

He later worked with David and Tina and considered himself David's rival for Tina's affections. However he had ended up accepting their relationship when they left on a trip to get closer together.

Carl prepared a lecture years later after David's death where Tina and her friend Barry Allen attended. Unknown to Tina, Carl used his time in Central City as a way to test his experiment of replicating David's work out on the homeless. Murdering many victims. Carl later got closer when he stole David's notes from S.T.A.R. Labs. Using the finished formula on his dog, Carl used this distraction as a way to get away to test it again on a rabbit, however the Flash caught up to him. David outsmarted the Flash in order to give himself enough time to inject himself with the formula. He then went on a rampage and kidnapped Tina. Tina begged him to stop, because her husband had died after using the serum on himself. Carl said that she didn't understand, but that she would. He then attempted to inject her with the drug, but the Flash saved her. He then went on a rampage throughout the ghetto district of Central City but was defeated when the Flash wrapped a chain-link fence around him, immobilizing him until the serum's effects wore off, causing him to revert to his normal appearance.[1]

In 2018, The Monitor invaded Earth-90 and seemingly killed all of its residents. Because of that, Carl's fate remains unknown.[2]
