Fan Casting 4-D in Return to the DC Universe

Like her fellow members of the Ultramarine Corps, Captain Lea Corben was experimented on with a synthetic metagene, granting her the power to manipulate four dimensions. Out of the original four, 4-D was the first to be suspicious of their orders, and eventually helped convince the others that they were in the wrong to fight the JLA. After the battle with Grodd and Nebula Man as well as their time in Qwewq failed badly in addition to Superia's fall in the Final Crisis, 4-D had suggested the Ultramarine Corps returned to help the US government, being a task force for metahuman response in the Pentagon.
