I remade this thinking of the previously deleted Sandbox Sentai, but I really don't want it deleted again.
This is the world of the Sandbox Sentai. Hero Supporters. The Black World. There are monsters, and when someone wants to protect others or something precious, they awaken and a god grants them powers (limited to Sandbox Creator members). (Please don't delete this; if there's an issue, let me know.)
Affiliation: In Hero Supporters, she is Alice-ing, the supporter in charge. (In the Black World, she is a bioengineering researcher.) She wears a hat with a flower and is a 'closed-eyes' character who usually keeps her eyes shut. The Heroes killed her parents and fellow villagers, then took her into the Sentai under the pretext of raising her. Because of this, she grew to loathe Heroes and stepped into the Black World. (When creating monsters, she secretly digs up corpses from the Hero cemetery to experiment on.) Her usual speech is delivered with a smile and closed eyes— (She actively uses a unique, cunning, and creepy laugh to express madness and cold-bloodedness. However, when acting as a spy for Hero Supporters, she uses a kind, typical 'nice person' laugh.) When she gets serious, she opens her eyes to reveal a look of pure contempt. Trait: Rebirth is her ability. Weapon: Syringe
Weapon: None Ability: Time Manipulation Affiliation: Commander of the Sandbox Sentai Central Branch Techniques: Mega-gu Kick, Clock Up One of the Four Great Powers. Speech Style: Ends sentences with "-dane" (Not a dialect).
A Hero expelled from Hero Supporters. Weapon: None (Uses a spray that emits fainting gas). Ability: Unknown Affiliation: Black World Anti-Hero Speech Style: A bit sly and mischievous.
Weapon: None (Uses a bike depending on the situation) Ability: None Affiliation: Sandbox Sentai Hero Skills: Aji Kick, Aji Bike Bomber, Aji Power Punch, Aji Counter Trait: Biological younger sister of Yang Noeul. She is only rude to Yang Noeul.
Real name is Yang Noeul, Hero name is Red Sunset. Older brother of Yang Aji (Aji Rider). Weapon: None Ability: Flame-based Affiliation: Sandbox Sentai Hero Techniques Used: Beneath the Sunset Hill, Red Sunset Stoner Trait: Comedy character. He was a fan of Aji Rider before realizing she was Yang Aji. His speech is attention-seeking and his moods shift quickly.
Weapon: Kitchen Knife (Magic Wand) Ability: Magic-based Affiliation: Sandbox Sentai Hero Techniques Used: Slash, Deep Dark Blast (An ability, but deals only 1 damage) "I, the magical girl who protects justice, Purple Show, has arrived!" (She introduces herself this way only once and gets very embarrassed.) Trait: Accompanied by a fairy named Metacon (Purple Show's subscription partner and Slave No. 1. Purple Show gets embarrassed easily. Metacon's catchphrase is 'kkuru-ppang-pping-bong'). She acts shy, but if spoken to, she snaps back intimidatingly, so people find her scary.
Weapon: A pair of axes Affiliation: Former Sandbox Sentai, currently Black World Ability: Regeneration She has sad memories from the past and hates it when people leave her. Flo-Pin told God she wanted to be with her precious people forever, and in response, God gave her the ability to regenerate. She joined the Sandbox Sentai and fought alongside her fellow Heroes, but most died in battle. When the one presumed to be her lover or closest comrade died leaving only a brooch, she fell into despair. As she cursed her ability and lamented at the Hero cemetery, Alice-ing approached her. Alice-ing told her she did nothing wrong, insulted the dead Heroes for choosing death and leaving her behind, and persuaded her to join the Black World by saying her pain came from having loved. Then, she injected a brainwashing syringe into Flo-Pin's back. When King Blue greeted her after a long time, she tried to slash him with her axes, but due to his ability, she kept missing. She glared at him, asking how he could be here, and grimaced, telling him he should have stayed asleep in his coffin. (Presumed to be hostile toward Kim Blue due to past events.)
Weapon: Mecha Iron-chan, Bronze-chan, Gold-chan, Diamond-chan in order (Rideable robots). Affiliation: Black World Mechanical Engineer Ability: None Trait: Half of the persona is a woman named 'Walsun', and the other half is a man named 'Waldo'. (Walsun and Waldo have distinct personalities; Walsun speaks robotically and gets straight to the point, while Waldo speaks with a mad laugh.)
Affiliation: Sandbox Sentai Weapon: Unknown Ability: Absorption, High-speed Movement Trait: Presumed to be long-time acquaintances with Flo-Pin. One of the Four Great Powers. Always looks tired.
Trait: A monster created through experiments in the Black World. Follows orders from the Black World (usually Moing's orders). Affiliation: None (Black World, if anything).
