Fargus was a fun Beserker, he had Dialouge that seemed to fit with his battle theme, even though you get a Game Over for attacking him(goodbye all that time spent in his level, only to foolishly challenge him), and he usually kills the unit attacking him if he lands a hit.
I always found it funnier to one shot him with someone.
Then again, I've lost my love for FE7 after finding out that the European version had content removed...
