Dandadan's wild forms and emotions
For manga readers, this scene probably came as a surprise. For non-manga readers, Okarun doesn't lose control at this point (I won't say anything else to avoid possible spoilers).
What I find interesting about all this is that the manga also showed us what happens when a human with yokai powers loses control due to the influence of a second yokai. This happens with Unji Zuma starting in chapter 148 and later. And it's completely consistent with what appears in chapter 1 of the second season.
For those who don't quite understand the situation: Yokai powers are strongly influenced by the emotional state of the protagonists, and their appearance and manifestation can be altered. In this case, the influence of the yokai is driving negative emotions in Okarun and Momo. Unlike the monstrous transformation caused by the turbo when it first possesses him, now it's Okarun's induced state that brings him to this form, and as we can see, it's a different appearance than his initial one.
The other detail we shouldn't forget is that yokai are personality enhancers. The reason Okarun's yokai form is so depressed is because he already is. Just as Aira becomes more direct or Zuma more protective. Their personalities are there, but with an added intensity. Jiji's case is a little different because he's never piloting the ship… But it's important to remember that the appearance and personality of yokai forms is relative. It depends entirely on the state of their owners, and if any of them were to change drastically, so would their yokai form. Either because they change or because an external agent temporarily influences them.
Finally, remember that if this was the turbo's form when she was in control, it's because her negative emotions, laden with anger and rage, were winning. It's a wild, rough, and monstrous form. Not that of a yokai in control like Reiko's "cute" form. We can be sure the turbo has been raging for a long time, and for good reason.
