Chakron

Chakron is the third sage who holds a Star Cure in Mario & Luigi: Bowser's Inside Story. When Bowser first discovers Chakroads, Chakron (albeit unseen) explains them to Bowser. Later on in the game, when Mario and Luigi are searching for the Star Cures, they find Chakron atop a mountain, meditating. He explains that he has frozen in a pose for 1,000 years, gathering knowledge from the stars. He offers them the third Star Cure if they can use an attack that would shake the ground and break his pose. During his explanation, Luigi humorously tries to imitate his pose, but falls over. He then tries to tickle Chakron, to the annoyance of the latter.

At first, Mario and Luigi battle him. After 3 turns, the match is ended and Chakron becomes disappointed. He tells the bros that there is an attack in the wood that will free him of his pose. Mario and Luigi then learn Snack Basket in Dimble Wood, and use it in battle against Chakron. The bros. would need to get an Excellent in order to win the battle. When Snack Basket is used, Chakron will flip out of control and fall back on the ground. He will then slither towards the edge and fall off. Fortunately, he survives and he finds a new pose that satisfies him, which he plans to hold for another 100 years. Chakron then awards Mario and Luigi with the last Star Cure. He then offers to teleport the brothers back to Toad Town.

Chakron's last appearance is at the ending of the game. After Peach's cake is shown, Chakron's mysterious voice appears, congratulating the player. Then their status will be seen.

Trivia

 * Chakron's star cure is the only one Mario and Luigi gain outside of Bowser's body.
 * With 9,999 HP and 999 POW, DEF and SPEED, Chakron is actually the strongest boss in the game. However, as Chakron cannot be defeated, because his battle will be finished when a perfect Snack Basket is performed, the title of stongest boss in the game is awarded to Dark Bowser. The boss with the most HP is Blizzard Midbus and the boss with the most EXP is the Dark Star.
