WSTs are ... well, tiny! Legends figures just tower over them. "WST" is just a slang name which Anglophone fans have given to this line, the actual name is
Kyokushou Henkei which means "Extremely Small Transformations" and they are _extremely_ small. WST Ravage is only 1mm wide!

You didn't see my WSTs when you saw my collection, gdmetro? They were lined up in front of the TV next to those Beast Wars PVCs (mebbe you didn't notice them cos they are so darn small

)
