Gentle Step Twin Lion Fists: I would alter this ability slightly by allowing it to absorb a finite amount of Chakra. The Lions would essentially “eat” the Chakra. Also, based on the user’s Chakra affinity, the shape of the Chakra would change. For example, Hinata’s affinity is Wind, so it becomes a Lion, while if Neji, who’s affinity would be Fire for example, uses it, it would be called the Twin Phoenix Fists but would still function the exact same.
Fire = Phoenix
Wind = Lion
Water = Turtle
Earth = Dragon
Lightening = Rabbit
Byakugan Beam: Byakugan users are capable of expelling Chakra from all points on their bodies, so this would be a method wherein the user shoots a concentrated beam of Chakra from the Chakra Points in their eyes. Eye lasers basically.
8 Trigrams 64 Air Palms: An Air Palm/64 Palms combination technique.
Gentle Step Roaring Lion: An Air Palm/Twin Lions combination technique that shoots a ranged lion head.
Protective 64 Palms: Hinata’s filler technique that enables her to create a dome of blade-like Chakra around her.
Gentle Fist Art Tenketsu Needle: Senbon needles made from Chakra that are shot out of the fingers to hit the pressure points. Akin to what Kaguya did with her Rabbit Hair Needle.
8 Trigrams Fist of Kaguya: A beefed up Air Palm more powerful than Hiashi's Wall Palm, but still weaker than Kaguya's Vacuum Attack.
8 Trigrams: Air Kick: Air Palm used through the foot. Allows the user to fly like 8th Gate Gai
8 Trigrams Fanged Palm: An Air Palm wherein the air pressure rotates rapidly, creating blades of sharp wind that can cut opponents. Similar to what RasenShuriken and Fang over Fang do.
Byakugan Battle Avatar: - A battle avatar made of Chakra akin to Bijuu Mode or Susano’O, but far, far weaker, arguably on par with a simple Skeletal Susano’O. Like with the Twin Lions, the shape of the avatar would alter between 5 animals based on the user’s own affinity.
I can give more if you want, though you'll need to be specific on what types of techs you want since I have so many ideas (ei defensive, offensive, nature type, chakra absorption)
