Y'all know about the power the Rise boys get once they unlock their ninpo. But in Mutant Mashup, the 2012 boys get some powers too (Draxum Clutch Tm).
Large bodies of text ahead, be warned!
At the moment, the Rise fam retains the same ninpo abilities as in canon (Red: holographic constructs, Purple: mystic tech, Blue: portals, Orange: mystic chains). If you watched the show you know that Orange (Rise Mikey) gets mystic chains and fire, but in the Au he only has his chains. A small but important change.
The 2012 boys are the Rise fam's cousins so they get ninpo too, which is more geared towards the elements. I think I'd be fun if their mystic weapon's amplified their mystic powers to dangerous levels. Draxum likely kept the weapons locked up as they were "too destructive" when compared to the Rise fam's weapons.
DaVinci's ninpo is water/air. When using his mystic weapon (a pair of tekko-kagi claws), Vin can create violent whirlwinds that can throw enemies around. These winds don't affect Vin's family unless he is trying to catch them or himself. The claws grow or shrink depending on how Vin is feeling so if he feels super angry then the claws sharpen and grow longer. Once the claws are destroyed by Shredder, Vin unlocks another aspect of his ninpo which is basically water bending. He can pressurize the water to the point it can cut through anything. When Vin combines both powers he goes full typhoon mode.
Sanzio's ninpo is fire. His mystic weapon are a pair of gauntlets and can shoot fire from his fists or even breathe fire. These flames can be all consuming and Zio can't always control them once lit, but he learns how to temper them over time. Sometimes the flames burn his family so Zio isn't too keen on using them at first, but that changes once the gauntlets are broken. After the gauntlets break, Sanzio can set himself on fire for a limited time, his tolerance builds up as he ages. More importantly, Zio has more control over what his flames burn and how strongly they do burn. (Yoshi doesn't like his ninpo unfortunately, it reminds him too much of what happened to Miwa and Tang Shen)
Niccolo's ninpo is earth. His weapon is a two sided battle axe that can "shatter the earth." (Nico tried using the mystic weapon Purple was supposed to get but it didn't work for whatever reason). If Nico hits the ground, everything starts shaking, kinda like a mini earthquake. This kicks up a lot of spikey rocks that Nico can send over to the enemy, a bit like his family's ninja stars. Due to the near permanent results of his ninpo, Nico doesn't use it all too much which irritates him. Once the axe breaks, Nico can finally do what he always does, create something new. He can still cause earthquakes and force large rocks to jutt out of the ground, but he can also reshape the earth into whatever he needs and even walk through magma, though only for a limited time and with proper mental preparation. Nico starts off by making small lab assists but as he grows, he can create huge Kaiju sized golems.
Simoni's ninpo is electricity. His mystic weapon is a scorpion chain that helps him electrocute baddies from a distance. The first time Simon used his ninpo he took out the entire city's power grid. It was fixed really quick but Simoni's electric current was way too strong to be used around machines (Nico and Purple were paranoid for weeks). Thankfully, Simon got more control over the power output once the his weapon broke. Simon can now use his ninpo to tether things together and keep them in place, a little like a spider web (Big Mama absolutely loves this). The things Simon can do are simple but versatile like creating electric ropes only he can walk on or dangle from. His ninpo can give him a little burst of speed which he exploits a lot when running away from his bros. Maybe Simon can sense things a lot faster then everyone, probably because he can feel the electricity in the air or something.
