My reasonings per ranking

S TIER "The GOATs"

1. Spongebob: literally Mr. Nicktoon himself

2-5. Leonardo, Michelangelo, Raphael and Donatello: TMNT is a global phenomenon

6. Garfield: From comics to TV shows to Mario Party rip offs to movies to being voiced by Chris Pratt himself

A TIER "Imagine Not Knowing Them Lol"

7. Aang: Avatar alone is part of Nick's Big Three (Alongside Spongebob and TMNT) and is a pop culture juggernaut

8-10. Patrick Star, Sandy Cheeks and Squidward: The best friends and grumpy neighbor of one of animation's biggest icons

11. Shredder: As the main antagonist of the TMNT, he's arguably one of the most iconic villains in fiction

12. Plankton: Same logic as Shredder but Shredder have more longevity comoared to Plankton

13-14. Mr. Krabs and April O'Neil: Being a Spongebob and TMNT character respectively is enough to boost them this high

15. Korra: The main characters to Avatar's sequel. Though more controversial than Aang ever was, she still became a Nickelodeon staple

16. Zuko: The most iconic redemption arc in all of fiction

17. Danny Phantom: The Link to SpongeBob's Mario. Though his show is in the "underrated but has a massive following" category. Him alone appeared in multiple games and has had two graphic novels recently

B TIER "Popular But Not As Iconic"

18-19. Toph and Iroh: These two are arguably the most beloved characters in ATLA, which I remind you is basically a globally known franchise

20. Azula: Same logic, as she is the most iconic villain in ATLA

21. Lincoln Loud: Basically the mascot for Modern Nickelodeon l Loud House is quite a successful show with how many seasons it has

22. Lucy Loud: Though not the most loved Loud Sister in the fandom (That honor goes to Luna), she's still a fan-favorite in the show and may be iconic among casuals and appeared in more Nickelodeon crossovers than any of her sisters (Lynn technically has more because of the Nick sports games but those aren't as well-known as NASB or Kart Racers)

23. Jimmy Neutron: Though not as relevant now, he was a icon back in the early 2000s, often seen on par with Fairly Oddparents itself

24. Reptar: Sure, Rugrats was one of Nickelodeon's biggest titansl.. Reptar himself is a minor character, a parody of Godzilla. But still, that doesn't change the fact that he's often seen in plenty of merch, video games and is iconic to Rugrats

25. Ren and Stimpy: As one of Nickelodeon's first cartoons, that legacy alone boosts them up, as well as being revolutionary at the time for pushing the boundaries of what TV animation can do. What drags them down however is lack of modern relevance and the infamy of both their adult party cartoon as well as their controversial creator

C TIER "Has Their Fans"

26. Catdog: Quite popular in the 90s and was at one point considered to be Rugrats' successor by Nickelodeon itself... until Spongebob came along

27-28. Zim and Rocko: Honestly quite similar. Considered cult classics and having a dedicated fanbase despite their shows ended years ago as well as having their own movies later on

29. Jenny Wakeman: MLAATR is one of the more underrated shows in Nickelodeon, Jenny specifically is boosted by being part of Nicktoons Unite and in a lot of recent Nick crossovers like NASB and Dice of Destiny that keep her relevant

30-31. Helga and Gerald: Both Arnold's bully and best friend, and Hey Arnold is a Nickelodeon classic. But it would mainly be the 90s kids who'd actually know them

32-33. Nigel Thornberry and Hugh Neutron: The memes alone carried their popularity and relevance

D TIER "I Think I've Heard of Them"

34. Rocksteady: Though yes, him and Bebop are TMNT fan-favorites, he doesn't always appear in every iteration of the franchise

35: Ember Mclain: A fan-favorite among Danny Phantom fans, but only stars in a few episodes and have certain... people in the fandom that dampened her reputation a bit

36-37. El Tigre and Angry Beavers: Honestly the same boat of "Underrated Gems" that has a small but dedicated fanbase. El Tigre slightly higher since he's part of the main 6 Nicktoons Unite squad

E TIER "Who?"

38: Powdered Toast Man: Though iconic in Ren and Stimpy, those who barely know the show would probably not know this guy even existed

39: Oblina: The show itself is quite the deep cut pick for the first game
