Dodrio is a interesting case. Two heads are like, really cool to hang out with (the middle and right ones specifically), being extroverted, funny, just some good banter.But the third head (the one that grew between the evolution stages) is problematic, being less mature, more argumentative, and asshole, just always trying to start shit and dragging the whole experience down. Plus they would be annoying to buy rounds for, since all three heads get drunk separately with different taste preferences
