So Alice vs Tiffany eh? The girl who can do anything vs the Girl who is always the 1%. The hothead vs the cold bitch.
Alice's Abilities:
1) Orbs: She can summon condensed Dark Energy around her hands which acts as a strong repulsive force on contact, and it can act as a barrier for pretty much every tangible attack, melee, projectile or energy based. The orbs can also be used to propel her and augment her mobility.
2) Graviton Impact: She can smash her fist orbs together and launch a repulsive wave in a radius around her. The effective radius is fairly short, 5-10 meters and it loses potency the further the target is from her.
3) Graviton Bomb: She can create an ball of Dark Energy and throw it. It explodes on impact and deals devastating damage. The force of the explosion depends on how much power she poured into the ball.
4) Gravitational Pull: Alice can make a target "fall" into her. Seems to be especially effective against flying targets.
5) True Graviton - Minute Collapse: The opposite of Graviton Bomb. It throws a ball that creates a strong attractive force and the affected target collapses under it's weight.
Tactical summary:
Alice after her evolution is a well rounded combatant. She has a strong passive defense, her orbs are pretty much indestructible and can shield her from any physical and energy based attacks. She has ranged attacks, a personal aoe attack that can deal heavy damage around her without needing to target something, and a way to pull ranged or fleeing enemies to her.
Her main problem is that all her attacks are telegraphed and she doesn't seem to be able to mix and match her abilities. For example she can't maintain her fist orbs while preparing a Graviton Bomb, her new attack requires both hands, etc.
Tiffany's Abilities:
1) Light Radiance: Tiffany can increase her luminance. The effects at low levels heal and rejuvenate the affected, but at higher levels she can cause blindness and damage through light beams.
2) Light Form: Tiffany can turn into light and move at it's speed. She can use this speed to create momentum for her physical attacks.
3) Exceptional Mobility: Tiffany can hover and she can move at light speed in a straight line.
Tactical summary:
Naturally, the combination of light speed and ranged attacks should make Tiffany one of the most powerful combatants. Light speed is so effective that at least at level 2, the only way to observe her is by tanking her attacks enough to understand her "rythm" which puts her opponent in an unfavorable position.
However her ranged attacks seem to limit her mobility and she is very weak physically. Perhaps it was Michael's power and resistance to energy based attacks that made her seem weak, but both in her fight against MC and Michael, they could just take her melee hits without any problem.
Engagement:
Tiffany has the initiative thanks to her better mobility and speed. She moves so fast that her opponent can't know where she is at any time. So even if she is visible at the start of the fight, the attack can come from anywhere.
Who I think wins:
If Tiffany's fight against Michael is of any indication, she is terrible at this. Not only she gave Michael the initiative when she could just start blasting him with her light beam, but her melee attacks are so weak that Michael wasn't even bothered by it. Alice has good passive defenses and a punch from her hurts a lot so it's plausible that the exact scenario will repeat.
If I was "controlling" Tiffany like an action videogame, the fight would look very different, although her lack of power is still a serious problem.
It's possible that Tiffany's ranged attacks mess with her mobility. This is really bad because Alice's Graviton Bombs are one of the most powerful attacks we've seen in the game and she is eerily accurate with them.
At this point, I can't see a way to victory for Tiffany. However she should have a relatively easy time beating her if she could just hit n run with ranged attacks. Alice's Gravitational Pull seems to be targeted but she would never see Tiffany so she would have to play full defense and hope that Tiffany becomes exhausted before trying to attack.
