Bob is a student at the New Domino City Duel Academy and a friend of Leo and Dexter.
He appears in the second season as one of the many students of Domino City's Duel Academy. He hangs around with the twins, Leo and Luna, as well as with Patty, and Dexter, who also are in his class.
Bob and the rest of his class were going to be expelled from the Duel Academy by Rudolph Heitmann until Yusei Fudo challenged Heitmann to a Duel to prevent this.
When Lester enrolled at Duel Academy as a normal student, Bob was impressed with Lester's skills. Later on, after Lester defeats Leo and Luna, it is revealed Bob no longer knows who Lester is.
He is often seen in the stands with his friends, watching Team 5D's' Duels in the WRGP.
During Yusei's Duel with Z-one, he is seen cheering Yusei on.
The only shown card in Bob's Deck is "Flamvell Guard".
- ↑ In the dub, Lester claims that Bob beat Luna. This is not present in the original.
