There's 8 Constructicons here. While they are distinct characters, to be honest they are not very compelling and tend to blend together, the G1 versions at least (to me). So I've made one role for that and for the sake of keeping the page tidy. I'm open to casting multiple people here, but essentially the voice can be any kind of 'blue-collar construction worker' sounding voice. I know, not a great description, but I like to let people come up with their own ideas!
