The Scotsman is a secondary character from Samurai Jack. He is a loud and boisterous Scottish man who is an ally to Samurai Jack.
Half a century later, he is seen to have (unlike Jack) aged significantly and changed in appearance. He has sporting gray hair with two smaller braids for his mustache and a plaid eyepatch. As for his arsenal, he retains his own magic sword, and is shown with an upgraded leg in the form of a minigun. He and his wife had, raised, and trained several dozen young female Scottish girls as their children. Later on, their children joined their father to fight Aku. During this time, he has become a shadow of his former self due his advanced age, confinement to a wheelchair and requiring Flora to assist him in battle, indicating that he cannot fight like he used to anymore.
The Scotsman was killed by Aku when the former assaulted him with a barrage of insults. Fortunately, he returned as a ghost in his prime age. He then told his daughters that they regroup, plan to fight for another day, amass a larger army and most importantly, find Jack and then battle Aku once more. (Episode XCVI)
He comes to aid Jack against Aku with his daughters as well as the rest of Jack's allies. After Jack destroyed Aku in the past, it is implied that the Scotsman, his wife and their daughters were erased from existence.
"What do you think of that, Mr. Pajama-Wearing, Basket-Face, Slipper-Wielding, Clype-Dreep-Bachle, Gether-Uping-Blate-Maw, Bleathering, Gomeril, Jessie, Oaf-Looking, Scooner, Nyaff, Plookie, Shan, Milk-Drinking, Soy-Faced Shilpit, Mim-Moothed, Sniveling, Worm-Eyed, Hotten-Blaugh, Vile-Stoochie, Cally-Breek-Tattie?"
"Magic Runes, laddie! All them fancy moves will get you nowhere. Now quit your jumpin' around and get to fighting!"
I ain't lost, ya tree ogre. I might be old, but I've lived long enough to see the world rise against your tyranny! Admit it, ya big oaf! You're scared. The samurai is still out there inspiring people by the thousands. After all these years, you're powerless against him. You've been shivering like a wee baby, hiding in your crib, afraid to show yourself 'cause ya know he's out there, and you can't do anything about it! (laugh) You're just a big baby! Why don't you go cry to your mama?
I be back, and in me prime no less! (returns in Ghost Form)
"Don't squash him, Muffin! He's a friend of mine!"
