SquidMask is a Shadowblood/Merman hybrid, and is the central comedic relief of WZRP. He is used by Tengen Toppa Lazengann.
SquidMask appears to suffer from some form of insanity, as he will talk to things that are not there (secretly breaking the fourth wall to speak to users), or will do insane things, such as flipping car that he is driving to prove a point, but is completely unfazed when it stops, and drives the car normally, as if it never happened, suggesting there is more to his madness than simple insanity.
SquidMask is a 60-something year old Shadowblood hybrid, whose past appears to be mysterious, and mixed between conjecture, lies, and facts that makes up, but are somehow all true. Some believe he is just a lunatic, and some think that he may be a Shadowblood deity hidden in disguise. Whatever the case is, SquidMask is somewhat respected by everyone, despite his aloof personality, and ridiculous abilities. The first known sighting of SquidMask seems to have been meeting WolfMask and Quet, followed by appearing in the Neo Empire, before his apparent 'death' at the hands of the Shadowblood 'Z', before disappearing from the universe for a while. After his subsequent revival by Kamen Rider Kiva, and transformation into a fangire, he returned to the land of the living, going on to torment/humor the universe in several ridiculous plots, that seem to have little to no connection to each other. Recently he began to have something of a feud between himself, and the Viledrode Detective Cypher, as well as Tazarus himself, leading to several antics between them. He would later meet the Shadowblood FlamingoMask, and accidentally drag him into his feud with Cypher.
- SquidMask was one of the first Shadowbloods, following FoxMask, WolfMask, and CoyoteMask, but preceding Quet, and the subsequent Shadowbloods.
