Cable usually has a jovial happy-go-lucky attitude pulling jokes and pranks, you can usually catch him being incredibly hyperactive and friendly towards everyone he meets, however it's pretty easy to tick him off causing him to have short bouts of extreme emotions to a dramatic degree.
Cable also happens to be pretty gullible, despite having the internet quite literally at his fingertips he will take everything you tell him at complete face value. Due to this belief that everyone should be believed Cable is naturally very sincere at best and unfiltered at worst.
