Mayor Dobe and his wife in Final Fantasy VIII. Just wanted Squall to give that self-righteous jackwagon a boot in the middle of his ass.
Jann Lee in the DoA games. The constant high-pitched Bruce Lee screaming drills into my eardrums.
Roman from GTA IV.
Kratos from the God of War series.
Most annoying game character of all time: Anyone who screams into his mic during an online game should get his ass booted instantly. Full stop.
