Idea №3 David & Goliath (but not really) x Worm
Alt power Taylor.
Taylor gets the power to split herself into 2 bodies, each can turn into either "David" or "Goliath" (but there can't be 2 Davids or Goliaths at the same time). She can also turn into either David or Goliath without splitting (more on that later on). Both the split and the change happen instantly with a small flash of light blue... well, light. Can use weaker, about 2 times weaker, versions of powers of both forms without splitting or turning into them.
When split: if one of the bodies dies it is absorbed into the other body. After that Taylor can split into two bodies again, but it takes some time for the other body to recharge after death, a minute or so. When split into 2 bodies Goliath gets the full benefit of David's thinker ability because both bodies share one mind. Both bodies can use weakened powers of both forms, same as the normal, unsplit body.
When taking either David or Goliath form without splitting, the powers of this form get two times stronger. The same increase in power for either of the forms happens when one of the split bodies dies and gets absorbed into the other body.
1) "David" - blaster (can create and shoot stone-like, extremely durable projectiles at supersonic speeds from any part of the body, but only one at a time, with an interval of at least half a second long between each shot, and only when not using the mover power, can charge up the shot for more power, speed and penetration, but has to wait for a few seconds after that to shoot again, can still use mover power while the blaster power is on cooldown after the charged shot, can change the shape, but not the size, of the projectiles before they are created and add the spin, in any direction, while charging the shot), mover (can move at extremely high speed,ignoring gravity and air resistense, increases traction when toughing the surface) and thinker (the world is moving in slow motion, increased analytical ability based around finding the weakness, can discover the weaknesses of people, objects, powers, and pretty much anything, both physical and psychological, but has to observe the target over a period of time for all the weaknesses to be revealed, doesn't work that well on Endbringers and Scion for obvious reasons). 4/5 of Taylor's normal hight.
2) "Goliath" - brute (strong, tough, slowly regenerates, unnaturally heavy, also has an armor coating that can regenerate), striker (think of it as an opposite of "reinforcement" magic from Nasuverse, can make anything that is in direct physical contact "weaker" in an instant it touches the body, making it even harder to damage Goliaths form, for example, a blade would get duller and more fragile) and shaker/master (can project an aura that enhances already existing negative emotions). 6/5 of Taylor's normal hight.
Both forms look like almost androgynous and featureless, except for the "hair" (yes, that hair that Taylor is so proud of), humanoid golems made from some dark, barely transparent blue-ish crystal. Goliath also has a yellow-ish, almost transparent crystalline coating covering every part of the body, except for the "hair". The "hair" looks like its made from the same material as the bodies, only darker in colour, closer to black then to blue. Both forms don't bleed, but shatter and crumble.
Normal body Taylor (or Taylors): 50% power strength of both David's and Goliath's power sets.
David & Goliath forms, 2 body split: 100% power strength for each form.
David OR Goliath, one body: 200% power strength for either of the forms.
