Fizz vs Karthus Matchup Summary

The Fizz vs Karthus matchup is a decisive matchup in League of Legends ranked play. Based on 9 recent matches analyzed, Karthus wins with a 77.8% win rate compared to Fizz's 22.2%, giving Karthus a 55.6 percentage point advantage. Karthus dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Fizz players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential. The most significant statistical gap is in sustain, where Fizz leads by 187 HP/min — a difference that heavily influences the outcome of trades and skirmishes. Karthus has a strong advantage in this matchup. Fizz players should play defensively, prioritize safe farming under tower, and look for opportunities created by jungle pressure or Karthus overextending. Avoid prolonged trades and wait for team fights where positioning and coordination matter more. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Damage
924Fizz
1,165Karthus

Sustain
874Fizz
687Karthus
