Notable Attacks/Techniques:

- Atsu Atsu no Mi (Heat Heat Fruit): A Paramecia - type Devil Fruit, this fruit gives the user the ability to produce and control vast amounts of heat. The major strength of the fruit, as demonstrated by Don Achino, is that its user gains the ability to produce vast amounts of heat, more than can be normally produced by a regular person. The Devil Fruit user can use this heat to melt anything they touch. The user is also able to use it to either protect themselves from physical blows or attack opponents with various heat-based attacks. Because the user has the ability to regulate their temperature, they are able to withstand varying temperatures of extreme magnitude, from being surrounded by the freezing cold of a winter island to being completely immersed in molten lava. The heat produced is also affected by the user's temperament. If the user is calm, the heat that is produced is moderately safe. However, if the user is angry in any sort of way, the heat that is produced becomes so dangerously high that the user can melt everything around him. Their heat can also drastically affect the environment around the user and can wake up sleeping volcanoes in the vicinity.

- Netsuryou Up: While fighting against an opponent, Don Achino is able to increase the amount of heat he produces with this technique. This technique has varying levels which include 3000 degrees, 5,500 degrees, and a maximum level of 10,000 degrees. As Don Achino raises his temperature, the redder he becomes and the more dangerous his techniques become. At his maximum level of 10,000 degrees, Don Achino turns completely bright red-orange and his stomach, in particular, turns golden yellow.

- Atsu Gesho: Using the hot air that he produces with his body, Don Achino creates a whirlwind of hot air. With it, he sets it on to an opponent.

- Steam Iron: Whenever his opponent falls onto the ground from any of his various heat-based techniques, Don Achino is then able to belly flop onto the fallen opponent with his belly producing large amounts of heat.

- Atsuyaki Tamago: Using his Devil Fruit powers, Don Achino creates from his hand's balls of pure heat which he calls Atsuyaki Tamago. With these balls, he throws them at an opponent as long-ranged projectiles. The technique's name is a pun referring to a roasted egg.

- Atsu Atsu no Gatling: A technique of Don Achino's which surprisingly shares almost the same name and execution of one of Luffy's trademark moves. While heating up, Don Achino sends a barrage of punches towards an opponent. Though the punches themselves don't reach the opponent, several Atsuyaki Eggs are created by this flurry and sent towards the opponent.

- Atsutto Odoroku Hana Jet: Using the steam that comes out from his nose due to his heat, Don Achino blows hard on his nose and propels himself through the air like a jet. With this, Achino is able to move within the air and dodge attacks from opponents.

- Net Tire: While producing vast amounts of heat from his body, Don Achino rolls towards an opponent and attempts to run them over. While he is rolling, Don Achino resembles a large heated tire, and is capable of burrowing through solid ice and propelling himself through the air.

- Atsu Atsu no Net Surfing: While immersed in lava, Don Achino manipulates the heat of the molten rock and causes it to rise up in a massive wave. With him "surfing" on top of wave, he then causes it to fall onto an opponent. The technique's name "Net Surfing" literally means "Heat Surfing".

Notable OBD Losses:

Other: Don Achino was designed by Oda, but is still generally considered to be filler, due to his arc being anime only, and thus non-canon to the One Piece manga. It's also notable that, due to his powers, the only reason Luffy was able to defeat him was plot.
