[FairyKing]

Some other recurring characters, because every Sentai needs a supporting cast. I tried to develop them enough that they'd be at least somewhat interesting, but they wouldn't get much focus, their character arcs would be done either as subplots in the background or one single focus episode:

- Ramses Pharaoh, a mummy king and Cleo's father, and the commanding officer of the Monstranger project. He acts stern and distant, even towards his own daughter, and lets the rangers mostly handle things themselves while he's busy with monster politics. However, he takes his duty to protect monsterkind very seriously, and the real reason he keeps the Monstrangers at a distance is so he won't worry about sending them into danger. When Cleo is captured, he actually panics at the thought of never getting to reconcile with her.

- Webster, a large talking spider (roughly hand-sized) who knows a lot about monster folklore and likes to tell fun facts about other monsters he encounters, which sometimes gives the Monstrangers useful information but is sometimes just trivia. He's been Drack's companion for as long as the vampire can remember, serving a role somewhere between an advisor and a pet. Later on, he becomes poisoned with power-up potion and goes berserk, then consumes the regrowth potion as well and grows into the more monstrous Gigant Webster. The Monstrangers are able to save him, but he retains the ability to turn into Gigant Webster.

- TA.I.yo (pronounced "taiyo"), an artificial intelligence created by Hikaru to aid him in locating monsters and operating his equipment, appearing onscreen as a sun-shaped face. Its personality is calm and logical, and it often tries to be a voice of reason for Hikaru when his rage against a monster distracts him from the bigger picture. Its knowledge of monster folklore is similar to Webster, enough that the spider sees it as a rival, though TA.I.yo finds the idea of rivalry pointless and mostly ignores Webster's attempts to upstage it.

- Koharu Sato, a very ordinary woman who works as a saleswoman at Hikaru's company, though she's never met Hikaru himself. After getting caught in a berserk monster attack, she becomes determined to find out the truth about monsters, and her snooping combined with just bad luck means she repeatedly gets caught up in the battles between the Monstrangers and Grim's faction. At first she reacts like any normal person would, with panic, but she gradually gets used to it and grows braver, and whenever she meets the Monstrangers she asks them a lot of questions. Eventually Hikaru notices her and promotes her to his personal secretary.
