The Stand repeatedly goads its enemies into pursuing and triggering its ability, through mockery or threats. As Josuke discovers a new aspect to his Stand's bubbles, Wonder of U decides that the best course of action is to simply retreat. Much like the user, Wonder of U is fairly resourceful, as it takes care to avoid direct combat by utilizing Dododo De Dadada in the fight against Josuke and Mamezuku, and notably releases Obladi Oblada on Josuke when the timing is right. Wonder of U is perceptive, as it sees through a trap Josuke has been laying for it and quickly analyzes the threat that Josuke could pose because of a surprise injury. When it's finally wounded by Josuke's bubbles, Wonder of U is shocked that anyone could wound it. Under the threat of danger, it's surprised when Rai Mamezuku manages to get as close as a few centimeters to it. When Taoka threatens to expose the Locacaca Organization's illegal clinical trial, Akefu calmly points out how a disaster may strike the journalist before leaving. It's quite confident in its abilities, stating that nothing can approach nor hurt it. Wonder of U is a sentient Stand that is, unlike most Stands in the series, considerably expressive and holds a calm yet threatening demeanor. However, it displays the hospital director's face less often to Rai Mamezuku and Josuke Higashikata.Įven when threatened, Wonder of U remains calm Once it is revealed that Satoru Akefu and Wonder of U are the same entity, Wonder of U keeps Satoru's outfit and accessories.
