Nin-ken is a hard-working ninja wolf, at around 13 feet tall (though can get to be 16-18 or even over 20 feet tall if overfed), weighing over 2000 pounds (though this is 2 year old outdated information) he manages to be the silentest fat ninja ever. Nin-ken’s personality other than hard-working is very friendly and very gluttonous (obviously), he loves belly rubs but dislikes being trapped and forced-fed to make his body much bigger, though he will relent and agree if on his own terms.
