Fusion

Fusion is one of the things that only Steven Universe units can do.It combines two units when they get close enough to each others range.

However, you can only make certain combinations here:

Ruby + Sapphire = Garnet

Garnet + Pearl = Sardonyx

Steven + Connie = Stevonnie

(No other possible combinations are made in the game so far)

It's also notable to say the fusion of Stevonnie will not work if Steven or Connie (or both) are in costume

They are the only ones that have costumes so other units are not affected by this.
