Squard is a person of loyalty, as he swore allegiance towards the Whitebeard Pirates and was willing to risk his own life to save his friend, Portgas D. Ace. He was also very hurt when he lost his faithful crew to Gol D. Roger, and felt lost and sad until joining forces with the Whitebeard Pirates.

However, Squard tends to hold grudges of his past. He developed a hatred towards Roger for killing his old crew, and this hatred extended to Roger's son, Ace.
