The actor told Zap2it that Vince's "vitriol and obsession" will fade as the first season continues.
"You start to see the light and the shade," he claimed. "There was a lot of shade when this came in [and] a lot of anger. As I grow with the character, I learn he's not always angry... and not always obsessive."
He added that Vince will grow through his interactions with allies Max Malini (Keith David) and Orwell (Summer Glau).
"It's... characters like [those] that really bring that side of [Vince] out," he claimed. "It's an extreme circumstance... but it's also an incredible psychedelic world he's found himself in. It's like Alice down the rabbit hole."
Lyons also confirmed that Vince's relationship with Max will become more complicated.
"[Max is] the leader of a bunch of criminals, but he also takes [Vince] in and trains him to become The Cape," he explained. "One of the constant battles Vince has in accessing Max and what he wants from [him] is that sometimes he's a sensei and sometimes he's an obstacle."
The Cape airs on Mondays at 9/8c on NBC.
