In Mario Superstar Baseball, chemistry is a stat that signifies how well characters get along with others on the team. Every possible matchup of two characters has its own chemistry value ranging from 5 (horrible) to 99 (perfect) attached to it.

Interestingly, despite characters one might readily imagine not getting along well (Mario and Wario, Peach and Bowser, Luigi and King Boo, etc.) having bad chemistry, none of the "obvious" rivalries and bad relationships have the worst possible chemistry value of 5.

This one is used only for the matchups between Peach and Petey Piranha, and between Toadette and Bowser. This must mean that in the minds of the developers, these two pairs of characters harbor exceptionally deep hatred for each other.
