Activating Hunger Mode makes Buu more dangerous! This changes a few things, gameplay-wise.
-At activation, an empty Majin 'M' symbol appears onscreen.
Its level is indicated by the color it gets filled up with: yellow = LV1, red = LV2, black = LV3.
-Power Charging is still possible with MP+MK.
-Hunger Power Charge can be done by down+MP+MK.
-Can now perform Just Defend (press Back for high/mid attacks or Down-Back for low attacks at the instant an opponent's attack would have otherwise hit you). Succesfully performing it gives Buu faster recovery along with an health and Hunger Bar gain.
Just Defend can be cancelled into Buu Ball.
-Buu gains Guard Push, performed with 3P while blocking. Using this gives him steam as an indicator he cannot use it again until the steam stops.
-Gain access to Armor Mode (detailed below).
-Kill You gains Finishers at the end, there are three variants:
LV1 - Vanishing Ball.
LV2 - Chocolate Revel.
LV3 - Human Extinction Attack.
