Strainor is nervous and scared all the time. His major responsibility as a Saber Tooth warrior is to hold Sykor's leash, and since Sykor is constantly dragging him this way and that, it’s not an easy life. Strainor is basically allergic to pain and will fight hard in battle just to avoid being hurt. The other Saber Tooths know how nervous he is and like to play practical jokes, like making sudden, loud noises just to make him jump. Given that he spends all day trying to keep control of a crazed Saber Tooth, Strainor doesn’t really need help being afraid.
Strainor's name is a play on the word strain, giving it a double meaning; It can be used to refer to a type of stress, due to his frequent paranoia from his handling of Sykor. Likewise, it also reflects his status as Sykor's handler, always having to restrain him.
