Arch's personality mostly boils down to being immature and short-tempered. He regularly acts innocently and refuses to say swear words. He also isn't able to understand big words, implying he only has a simple vocabulary. Arch can be rather grumpy, especially towards Trowel and Beer, who constantly bully/prank him. He is also considered a loudmouth, since he tends to shout almost every time he speaks. He also can be a 'tough guy wannabe' when he gets angered. Hates being called "U rip-off"
