Im pretty sure you remember Tansformer the movie, well….let me tap in your memory lane once more shall we?
 
During the nearly end of Robot Storm, adagio forces and the rainbooms deadlocked on final battle in canterlot city causing the city itself destroyed in oblivion  
during that course sunset shimmer were fighting off against Adagio dazzle. Sunset was able to weaken adagio, however the siren herself saw the weapon and pretend  
but during that time Gamma saw adagio ploy and decide to stop her. Adagio begging sunset for mercy but Sunset Shimmer having none of that and decide to kill her but not before  
adagio pull out the weapon gamma was in the way tackled adagio causing sunset unable to shoot her.
 
Adagio manage to pull a grasp against gamma and pull the trigger at sunset, giving the bacon hair a fatal shot on the body. Weaken adagio aim her weapon and ready to execute sunset, with  
all her energy left sunset were able to deliver a fatal blow on adagio, damaging futher the siren. Gamma felt regret what she have done as she saw her mother battered and damage. With adagio side  
aria remarks to adagio that shes not that powerfull anymore and kick her, she call out the remainiing troops to retreat while the remaining adagio forces manage to carry adagio back to the dropship and  
retreat. The rainbooms won but it cost them in return.
