No Lilith got the best power cause phaselock is awful compared to phasewalk and phaselock not good at all and Maya is my least favorite siren, Amara has the better version

of phaselock

To add to my comment her tattoos aren't blue so it rules out phaseleech, It's the same color as Asha's power when she uses it in the comics again proving that it's likely animal control

No you don't know what her power is, It's between the laser she used in the trailer and animal control like Asha from the comics so she'd be a better FL4K, As for the laser she can probably put explosive, shock, fire or corrisive elements into it as well as normal guns, She's likely the first ever soldier type siren who can spawn different guns since the trailer shows her using a laser  

You're going off of everyone else's speculation and there are animals in the back shown to not attack her that's why I think it's animal control or to do with her laser

It isn't commandant Steele's power or Tyreen's phaseleech, All Commandant Steele did was power vault keys and Tyreen's ability will not be playable since it was used by an NPC
