The KO coverage calculator focuses on the question players ask during team preview: which of my Pokemon can remove each opposing threat? It compares six attackers into six defenders and summarizes OHKO targets, damage rolls, and moves that fall short.
You can start from ranked sample sets and then adjust items, abilities, natures, moves, rank boosts, weather, and other battle assumptions. That makes it useful for quickly checking whether a matchup is actually safe or only looks good because of type advantage.
For newer Pokemon Champions players, the page gives a simple way to avoid bringing Pokemon that cannot pressure the opponent. For stronger players, it works as a scouting screen for KO coverage, speed pressure, and preview planning before a set.
Results are a planning aid based on sample sets. Real battles can change with opponent spreads, boosts, weather, field effects, and move choices, so adjust important matchups before relying on a line.
