Apparently, the Thunderhand is granted to a user for only a limited time, for Luigi has not been seen using this ability since Mario & Luigi: Superstar Saga.
I personally think this should be removed. The reasons: We have no proof on whether or not it is truly granted for a limited time. Same goes for the Firebrand. Also note that Giga and Merri have the abilities as well, and know more about them than Mario and Luigi, which means that they have had them far longer than Mario and Luigi, which further goes against it only being granted for a limited time.--King Boo 11:06, 3 August 2007 (EDT)
You are right, I am going to remove it. Gofer
