Damn fry guy, he was annoying as anything.
Firstly I realised he was effectively a living embodiment of flame was in charge of world 4 which was the ice level. Here he is in the snow;
Secondly, my little 6 year old brain struggled to beat him, of course when I did he split off into five little FryGuys just made me quite a bit pissed off.
Outside of Super Mario bros 2, I'm sure he was in one of the Wario games, though not 100% and as IC mentioned he had a a few appearances in the TV show, well our little boyo also seems to have his own flamethrower business in the worst movie ever made.
Whilst I think FryGuy was a classic boss, perhaps this threasd should be renamed "Forgotten Video Game Villains?"
