Sugar Rush (シュガードープ Shugā Dōpu?) is a Quirk used by Rikido Sato.

Quirk Description

Sugar Rush allows Rikido to multiply his strength five-fold for three minutes by every 10 grams of sugar he ingests.

Rikido must consume the required sugar quantities for his Quirk to be activated in the first place. This can be achieved by eating any food items that carry enough sugar content, such as most sweets, soft drinks or even raw, granulated sugar. Once this condition is met, Rikido is able to convert the absorbed sugar into raw strength, with his body slightly bulking up.

When converting sugar into strength, his cognitive functions gradually drop, decreasing his intelligence and causing lethargy in the process.[1] Without a source of sugar, Rikido can't activate his Quirk.


Rikido is a straightforward fighter who takes advantage of the temporarily augmented physical might granted by Sugar Rush to punch his way through obstacles and enemies.

As part of his Quirk training, Rikido has developed remarkable skills in baking confectionery, and is implied to use said confections as a way to acquire sugar for his hero activities.

Rikido's costume comes with a belt equipped with pockets that hold small containers of granulated sugar, which he can take out to ingest the contents inside. This gives Rikido a quick method to empower himself.


  • Sugar Rush's Japanese name Sugar Dope (シュガードープ Shugā Dōpu?) is a play on the Quirk's effects: increased performance and reduced mental capacity.
