There is not much that stands out about Axis' personality except that it is able to feel love and kindness, as proved in the Pacifist Route. Axis is clearly not very smart, due to letting Clover escape many times during the Pacifist Route and buying into many obvious tricks, He also crashed into a couple of servers that one time, They also mistake you for Clover, the Cowboy with the soul of Justice, who was female, Sadly since it's been so long Axis forgot what she looks like.
