For me It's Bruno from HG/SS. I managed to Wiz though Will and Koga very easily but Bruno had one trump cart..his Machamp, i manged to beat most of his Pokemon fine but that Machamp is so powerful and has a lot of defense...i have to use my Electrode as a Suicide Bomber to do lots of damage to it..i still haven't beaten HG/SS because of his Machamp
Lucien from Diamond and Pearl. I was in the 'only train the starter' phase, and no matter what I'd do, my Torterra would always get fainted. It was so satisfying to take him down with a level 87 Murkrow when I traded it to Diamond.
