??? Gansley (Big 1)
Gansley’s the big, stout guy you see in the center every time the Big Five appear in the anime. Since WDKY doesn’t use the Noah’s arc (from Battle City), they’re still alive in the real world, but they don’t like Seto or Téa one bit! Gansley leads the Big Five in their quest against the corporate tycoon and his girlfriend.
??? Crump (Big 2)
Crump is the first of the Big Five to actually “appear” in WDKY. He takes a personal interest in Téa (just like he did in the Noah’s arc of the anime), and was actually her mother’s (Elizabeth Gardner) boss, though the two rarely interacted. Crump dies of a heart attack after Téa defends herself against his lascivious attentions in Chapter 13.
Clark Johnson (Big 3)
The lawyer of the group, Johnson is fond of using legalese to confuse people. He was also Téa’s father’s (Eric “Rick” Gardner) boss, though the two rarely interacted. Johnson is skilled at covering his tracks, because he knows the law so well and how to find the loopholes in it. When Seto called him in Chapter 9, he intentionally didn’t pick up– him and the rest of the Big Five were responsible for framing Kaiba for the murders of the Gardners anyway!
Frank Nesbitt (Big 4)
Of all the Big Five to hold a grudge, Frank Nesbitt would most definitely be it. While the other members of the Big Five managed to maintain semi-active roles in Kaiba Corporation by being in charge of its Board of Directors and heading up a variety of lower-division firms, Nesbitt’s division, in charge of making Kaiba Corp.’s once-famous weapons of war was shut down completely when Seto Kaiba took charge. He’s held a grudge ever since, and wants to restart his division to make a profit by selling weapons to terrorists.
Charles Leichter (Big 5)
Said to be Gozaburo Kaiba’s right-hand man, this smooth Southerner (that is, from the American South; in the WDKYverse, he speaks Japanese, but with a thick accent) was once the Vice-President of Kaiba Corp.– that is, before Seto Kaiba ousted him in favor of his younger brother. Easily the smartest and cruelest of the Big Five, Leichter is not one to be messed with.
