As mentioned in his Yo-kai Medallium bio, The Shark is related to "a certain well-known IT company president". However, he arbors a deep hatred towards Steve for being too focused on his job.
Abilities and Powers
Not much is known about Steve Jaws' Yo-kai abilities, although he is likely to possess considerable technical expertise as the re-creator of the Yo-Kai Watch Model Zero. After leaving Yopple Inc., he developed the Yokai Watch Dream and all its peripheral devices.
Steve Jaws first appears in EP027, where he showcases his latest gadget namely the Yo-Kai Watch Model Zero. This leads to a big sale in Yo-kai-lifornia, Yo-kai World.
He later makes a brief appearance in EP035, having been invited by Directator to star in the shark attack scene of his latest movie "Yo-Titanic-ai."
In EP078, he is revealed to have stepped down from being charge of Yopple Inc. due to a controversy about the Yo-Kai Watch Model Zero (claiming to have been the one who built it when it was Nate's grandfather). He is succeeded by Mark Shachiberg.
In Yo-kai Watch 3, he has gone into hiding somewhere in North America and is the one who builds the Yo-Kai Watch Dream and its weapon modes.
