O'Chunks is one of the main villains in the game Super Paper Mario. He is fought a total of four times in the game, making him the most encountered boss in the game (even though there is a huge gap between his first and second battles; Chapter 1-3 and Chapter 5-2). He speaks with a Scottish accent and his bushy ginger beard and eagerness to brawl are both Scottish stereotypes. However, the fact that his name begins with "O'" is an Irish tradition. Other translations use the Scottish patronym "Mc" instead, while in the Italian version, he has a stereotypical Roman accent.
O'Chunks was once the general of an army from a certain land (the name of which is not mentioned) for a period of time, during which he was able to successfully lead a squadron of one thousand troops across enemy lines. Unfortunately for him, one of his advisors sold him out and all of his men fell to enemy forces as a result. Count Bleck may have played upon his shame and depression to enlist him into his service, given that Carson claimed that Bleck made O'Chunks feel gradually worse until he finally pledged allegiance to the Count.

When he is fought for the first time, O'Chunks will attempt to Ground Pound, shoulder-ram and toss Mario as part of his battle strategy. Every time he is successful in tossing the plumber (despite only one HP of damage being done), he performs a victory dance. He has twenty HP in this battle.
When O'Chunks throws Princess Peach, he merely tosses her without doing the spinning and victory pose.
He is not encountered again until Chapter 5. In 5-2, he attacks the heroes, but loses to them once again. He asks them to finish him off because he failed the Count, but Dimentio then appears, offering him a chance at redemption. O'Chunks accepts his offer because he "lives for the Count", and then leaves with Dimentio.
O'Chunks is fought again in Chapter 5-4, this time having been brainwashed by a Floro Sprout. He randomly shouts out the names of various vegetables while in this form, which Dimentio nicknamed him O'Cabbage. After being defeated, the Floro Sprout on his head shrivels up and falls off his head, erasing his memory of the third fight. He attempts to engage Mario in battle once again, but eventually retreats back to Castle Bleck.
O'Chunks is fought for the fourth and final time in Castle Bleck. Here, he faces off against Bowser in a one-on-one fight as the much bigger Super O'Chunks (the player is unable to play as Princess Peach, Luigi, or Mario in this battle, as Bowser challenges him one-on-one). When he loses, the ceiling begins to collapse. O'Chunks stays and holds it up out of honor for Mario's party, giving them a chance to escape unharmed because " they gained the right to pass". Bowser remains behind to help him instead of leaving though, and after a pointless display of brawn and willingness to sacrifice themselves between the two, the ceiling presumably crushes them both.
However, it is later revealed that he (along with Bowser) survived the cave in because Bowser's weight caused the floor to collapse as well, and they both fell downward unharmed. In addition, O'Chunks also learned from Nastasia about Dimentio's treachery, and also learned from her where Bleck was most likely to be imprisoned. Later, Mimi takes him with her to Dimension D to assist Count Bleck. He and Mimi give the Count and Tippi enough hope to restore the Pure Hearts, thereby helping to defeat Super Dimentio.
