I don't care if people hate this queen for being the main protagonist of the show for the first 7 seasons, Emma had so many iconic storylines. Emma ripping off her dress in front of school? Iconic. Emma's entire eating-disorder storyline? Iconic. Young Emma was a boring nerd, but as she got older she really was such a queen and I will always love her for that.
5. Fiona Coyne (Degrassi 9-12)
I mentioned this about Alli, but it's probably even more prevalent about Fiona. She was never like my favorite character on the show nor was there ever one moment where I can recall as her defining moment, but I just loved Fiona since the second she walked into Degrassi and she was consistent the entire time. She was funny, kind, and her alcoholic storyline really was iconic. There's nothing I didn't love about Fiona. She deserved better than Imogen because Imogen was annoying as hell, but in a way, they were cute together.
