TuffyMon's 110 challenge opponents

Search for an opponent or filter by region, stage and type. The challenge covers 110 rows across 9 regions, with 105 distinct names. A name can appear again in another region or role; use the challenge number to identify the row you need.

Regions follow the game's order from Kanto to Paldea. Rows are grouped as Gym, Kahuna, Elite Four or Champion. Enter a complete team in the team builder to fill the failure-risk column, then sort by highest risk to find your hardest matchups.

Compare your team's threats

The Difficulty value is a challenge coefficient. Gym and Kahuna rows progress from 0.15 to 0.75 within their region. Elite Four rows start at 0.85, rising by 0.05 per row, and Champions use 0.88. Normal, Hard and Tuffest affect drafting; this coefficient belongs to the opponent's result calculation.

Your team's average BST and its attacking and defending type matchups affect each result. Champions use different type and risk adjustments, so compare the risk column for your team rather than choosing a replacement from Difficulty alone. Open a row to see which members create its weaknesses and which changes reduce them.

A cursed run always assigns a random row a loss. The table's percentage includes that chance alongside the row's ordinary risk. An uncursed team has 0% actual failure risk on every row and completes the 110-0 Challenge. Use the curse-removal guide to fix the conditions before chasing a lower percentage.

Watch for a shared weakness

If at least three members are weak to an opponent's type and at most one resists it, a cursed team loses to that ordinary challenge row. Against a Champion, this shared weakness sets ordinary failure risk to at least 75%, before the random forced-loss contribution.

For Rillaboom, Cinderace, Inteleon, Regieleki, Lucario and Tyranitar in Regular, Brock's displayed failure risk is 1.01%. The same team has 100% risk against Giovanni: four members are weak to Ground and only one resists it. Rillaboom's reduction is applied before the shared-weakness rule.
