1: Akuma Kira
It means Devil Killer in Japanese. It is essentially a giant mechanic left arm that utilises the fact that San has cyborg arms. It hooks onto his cyborized arm and allowing it to be function as if he always has an abnormally long left arm his whole life(Meaning it feels like a normal arm without feeling weird).

It looks like a red arm covered in scales. It has claws and a circular white sphere on the top of the palm. The hand is also capable of being fired to be used like a grappling hook and then retract. The whole length of the Arm is from Sans' Head down to between the foot and knee exactly in the middle. It has vents all along the arm that allow Sans to use Dust in it's arm mode to use either to cover the arm in ignited Dust, for movement by using Wind Dust or a mid range Dust Based attack.

2nd Form - Gun/Shield Form
It changes the hand and the parts near the hand open up, forming a barrel. It uses Dust as ammo to shoot 2 ways. Normal way, it shoots Dust bullets while the 2nd way uses a lot of Dust to shoot something almost like a laser beam using Dust. The forearm opens up as well, forming a shield.

3rd Form - Sword/Whip Form
The whole arm opens to extend out a huge blade that can act straighten or to use like a whip with the whip. The Sword changes colour to whatever Dust it is using.

2: Toku Katto - Secondary Weapon
It means Far Cut in Japanese. In terms of appearance, it looks like an oversized blade of a katana with a device stuck on it on a hilt with a tubing along the blade with the exit of the tube near the end of the blade. It is White in colour.

It is incapable of changing form making it difficult to use as a normal flamethrower. However San uses this to create powerful shockwave attacks. It works by spraying and igniting Dust, and using the shockwave to propel the Dust creating Dust-Based Shockwave attacks allowing a normal Shockwave to be much stronger.

Trivia:
-San means Acid in japanese. Very acidic solutions are shown as Red on the Universial Indicator.

-Kori means Ice in Japanese. Ice is white in colour.

-He might be slightly alluded to Allen Walker from D-Gray Man but i don't want to rip off other anime characters.

-His Symbol is A Red Fist with white ice cubes around it.
