There is one bit near the end of Disgaea where Laharl experiences something particularly traumatic (won't spoil it here), and he goes into a half-raging, half-anguished speech about it. That scene had a bit of an impact on me, so I ended up making a wallpaper based on it. The main image of Laharl in the field of flowers is from one of the anime eyecatches, and the quotes are from the random bits of angry ranting he does in that episode.
