Mothership is a fan-made monster that can be found in Level-Up Dimension.
It's a UFO variant. It's colored completely black with light blue shading. A pair of Mii eyebrows, eyes, and a nose are attached to it.
|Attack||Inflicts physical damage to one party member.|
|Steal HP Bananas||Steals all HP Bananas held by a party member, permanently removing them from his/her inventory.|
|Super Beam||Fires a damaging beam from its antenna. Uses the target's Magic stat for base damage calculation, which is then multiplied by 8 for the skill's total damage. Rarely used.|
|One More Time! (auto)||Allows this monster to perform two actions in one turn, each aimed at a different target.|
Trying to save up HP Bananas is basically useless due to this boss's tendency of stealing them whenever it has the chance. While it mostly performs regular attacks otherwise, beware of its beam attack, which inflicts massive damage, not helped by the fact that it depends on its target's Magic stat, which is then multiplied by 8 after calculation. Even though it starts with the usual weakness to magic attacks, it will gradually gain more resistance to them as the challenge goes on.
Like all Level-Up Dimension monsters, there's a rare chance of a level skip after a level is cleared, the likeliness of it happening increasing the more party members are in a critical state (less than 25% of their max HP). In Mothership's case, skips are not given starting at LV. 21 until LV. 25 has been cleared and are no longer given if its level is 46 or above.
