When you are selecting your characters in Team Select, you might notice a green Icon appears with numbers that change depending on what characters you place in your team. This represents your team's "Synergy."

The icon represents that the character has at least one passive or ability that conditionally activiates or provides a bonus with another character on the same team. The number represents the total amount of bonuses that the character benefits from.

If you press and hold on the icon, you can receive more details on which abilities or passives receive bonuses and which character provides that bonus.
