For the Channel:
- Network Decay: As said on the main page, the channel has moved away from ACTUAL Nicktoons in favor of original programs and imports (like the Yu-Gi-Oh! franchise). They've even aired live-action programming, including Power Rangers and NickCom reruns.
- Snark Bait: The channel became notoriously mocked by fans due to the aforementioned Network Decay but also because it's been noted that whenever a Nick cartoon is not doing well (whether it's not popular or it's not in the same level as its two juggernauts), it's thrown into the Nicktoons channel and let it quietly fade away.
For the series of Cartoons:
- Broken Base: Do KaBlam, Pelswick, Mr. Meaty, and Wayside count as Nicktoons?
- Ensemble Darkhorse: Invader Zim, hands down.
- The Scrappy: Fanboy and Chum Chum and Breadwinners are not without fans, but are notoriously unpopular.
