Moebius D & J (Xenoblade 3)
Phase 1 has them separated, You fight D Or J for the first 1/4 of their health and the other for the next 1/4th
D will attack with his blades and is a much more physical fighter, and has a few abilities
Unstoppable Spear - D throws an energy spear at a player, this Spear deals fire damage over time
Grim Rush - D slashes downwards and anyone hit is trapped in a multi hit combo
Chaos Arch - D will Dash across the stage dealing damage to anyone in his path
Dread Edge - D throws an exploding projectile forwards
J will attack with his fists and jumps and has different abilities
Brave Hand - J Leaps Forwards slamming his hand on the ground and this produces a shockwave on the ground.
Incarceration - J will spin around moving across the ground and end by clapping his hands together
Healing Light - J will start to heal himself but this can be interrupted by dealing big damage
Regardless of which one is attacking J will also use
Decoy Soul - An ability that summons a mini clone of D or J which performs much weaker and smaller moves than their bigger counterparts and can be KOd early
Before the second phase, J will detonate any remaining clones.
Phase 2 has them Interlink. This is activated at half health
They essentially act as a faster and more powerful D with some new abilities
D & J has all of D's abilities but are more powerful
D & J Also gain
Doom Rain - D & J jump in the background and summon a volley of projectiles onto the stage
Beyond Death - D & J float and slash forward with an energy Sword
Sanguine Fire - D & J only use this when they have a quarter health left, this just increases their speed
They are fought in the Cloudkeep from Xenoblade 3 at night (basically a snowy stone platform above the clouds)
