Disney vs Non-Disney
Soundwave has done no actual fighting so far apart from firing at Captain Gantu's ship. He did play a major part in Megatron's involvement however. When Megatron was mortally wounded, Soundwave carried Megatron off to Mok Swagger who rebuilt Megatron into Galvatron.
Transformers vs Disney and Non Disney Villains
Soundwave's first actual fight appeared in this series. As a matter of fact, he had the very first fight in the sereis, not counting the practice round.
Soundwave faced Ember Mclain, a rock and roll ghost. Ember was holding a concert in a club called Danceitron. She gained power by the cheering audiance. Knowing she would eventually become too powerful, Soundwave interrupted her concert. After facing harsh attacks, Soundwave managed to activate the sprinklers or the building, making the audiacne stop cheering and causing Emeber to lose her power.
- As revealed in the fanfic, Soundwave has feelings for Ember. His loyalty to the Decepticons is greater than those feelings though.
