eventually they will add echo to stadium, this is how i would do it. the main problem will be balancing the copy system, if you use your itens or the oponents, do you also gain ther other's character powers and so on and so forth

POWERS:

Replacement: after an hero is eliminated, can copy them for 2 or 3 seconds(needs to be close like mercy Resurrect)

Arsenal duplication: while reloading can copy only the primary fire of the target,(5s duration and a 20s cd)

duplicate storage: when Duplicate is fully charged can still charge the ult of the hero you are transforming into with 50% efficiency.

Superior copy: During duplicate has 50% cooldown reduction.

Adaptative bombs: Sticky bombs has 6 charges, each with 1 bomb and takes 1s to charge a bomb( normal sticky bombs takes 6s to recharge) activating it use all the charges.

Focusing ray: Focusing beam pierce through enemies with less than 50% hp

Razor wings: deal 30 ability dmg to enemies you colide with during flight

aerodinamic: increase your speed during Flight and during Glide

second wind: flight has 2 charges

energy shield: using one ability initiate your shields regen

reinitiacion protocol: when you die can Resurrect with 1hp and all your abilities in cooldown. 90s cd

wings atack: quick melee send a piercing attack that deal 20 attack power dmg

ITENS:

polishot: fire 1 extra projectile in the middle of the triangle

Bigger storage: Sticky bombs shoot more bombs

Military bombs: Sticky bombs has a bigger explosion radius

long beam: Focusing beam has more range

Tanker duplication: now duplicating tanks don't have the hp reduction and gain more armor

lasting copy: eliminations increase the duration of duplication by 2 s

tell me how you guys feel about this concept and what else can be added to her kit when she joins the stadium
