This article is about a/an villain in Kamen Rider W.

Mick (ミック Mikku) is the pet of the Sonozaki Family, namely Ryubee Sonozaki, also known by its monster identity Smilodon Dopant (スミロドン・ドーパント Sumirodon Dōpanto).

Unlike the other members of the family, Mick is more of a neutral character and only acts on Ryubee's orders, and goes into the ownership of the Narumi Detective Agency after Ryubee's death.



While normally appearing as a regular blue British Shorthair, Mick has shown to be more intelligent than the average house cat, appearing to know how to transform into his Dopant form and back. Out of all the Sonozaki Family members, Mick appears to favor Wakana Sonozaki, though will faithfully follow Ryubee's orders. Ryubee had Mick trained to go to a set location, when he moved a metal spoon back and forth three times, then pointed to that location. This was something Philip knew, leading to the Smilodon Dopant's defeat at the hands of Kamen Rider Double CycloneMetal, as Double used this trick with the Metal Shaft to have Mick sit calmly while he prepared his Maximum Drive. It seems that losing the Smilodon Memory has changed Mick for the better as he seemingly obediently came with Shotaro to the Agency without putting up a fight as well as allowed Akiko to hold and pet him without resisting.


Mick was named by the son of the Sonozaki Family, Raito (now known as Philip). He is often utilized by the Sonozaki Family to deal with matters outside their estate, such as hunting down Philip and traitors, as well as bodyguard and spy. While targeting Kyoko Todoroki, the Smilodon Dopant defeats AccelTrial before Double CycloneMetal catches the cat off guard before destroying his Gaia Driver and Smilodon Memory with the Metal Stag Break Maximum Drive. After Ryubee's death, Mick is adopted by the Narumi Agency for Philip. Shotaro is often shown buying him special cat food.
