Vegeta wears a new armor model with a black long-sleeved jumpsuit and a chest piece which features Whis’ signature. This armor was developed by Capsule Corporation to replace his previous model, and gained its Whis symbol during a training session with him when Whis playfully drew his symbol on Vegeta’s armor using his superior speed. This model also seems to feature armored shoulder sections similar to those of the basic model, rather than the straps of Bulma’s model. Appears under the name Whis Symbol Battle Suit in the Dragon Ball Xenoverse series.
