- — Mr. Genetor
Mr. Genetor is a boss in Mother 3. It guards the generator of the Thunder Tower, and is encountered while Lucas and friends are fleeing from Fassad and two other Pigmasks. When they pass the tower's generator, Mr. Genetor appears and attacks them, having deduced the party to be a threat to the generator.
The name of this boss is a shortening of the word "generator", and may also be a pun on the word "generator" and "janitor".
When this boss is encountered, it is seen inside of its "work station" (the generator itself). In battle, the generator unit is not to be seen, and is replaced by a yellow/black background. Also, its in-battle sprite's colors are noticeably different from those of its overworld sprite. This may be because of the yellow background's reflection off his metal surface.
During the battle, Mr. Genetor can use electrical attacks like Volt Chops. While he is powered, all physical weapon-based attacks against him result in 20 points of recoil damage; this also nullifies rhythm combos. After some time, he will store electricity for a turn, then unleash his Discharge Zap attack, which inflicts high electrical damage to the entire party. After using this attack, the machine loses power, changes his sprite, and stops attacking for several turns while he recharges his batteries, giving the party several turns to attack him without taking recoil damage. Mr. Genetor is weak to ice and the flash will make him miss.
Mr. Genetor heals slightly while recharging, but this is usually not enough to compensate for the damage he will take from the party while vulnerable.
When his health becomes very low (to the point where one or two hits will finish him), his charger will break, leaving him permanently disabled and open to attack.
Its battle sound is Battle Sound 56 which falls under Code Numbers 927 for regular attack, 928 for Smaaaash! and 929 for Miss.
