Karthus vs Fizz Matchup Summary

The Karthus vs Fizz 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 players can confidently pick into Fizz and play aggressively from level 1. Look to establish lane dominance early through favorable trades and zone Fizz away from CS whenever possible. Understanding these matchup dynamics is essential for champion select decisions and in-game strategy when facing this lane opponent.

Damage
1,165Karthus
924Fizz
