Dwight Graham was a human scientist. He was nicknamed "Boffin" since he was clever with mechanics.
He worked for Buck Sharon at Global Response, but after the war with the Myloki started, he left to work for PRISM. He developed a device that he thought could disintegrate Grant Matthews. It appeared to succeed, but Matthews reformed later from the dust. Graham was killed during an attack on SKYHOME. (PROSE: The Indestructible Man)
Behind the scenes
"Boffin" was a thinly-veiled copy of "Brains" from Thunderbirds.
