Backstory: Born into the Omnic Crisis, Laila was forced to grow up and defend. Her village wasn't as technologically advanced as other places around the globe, so Laila had to compromise. Enriched metals in caves near her village were farmed for her villages defense. She took those metals and made a suit of armor and a couple of arm blades for herself. (Torbjorn would be impressed).
Side Note: In the "Recall" animation, Reinhardt is shown in Greenland on the map. What is he doing in Greenland? I feel like this would be a perfect segway into Laila joining Overwatch. Reinhardt could recruit her.
Abilities: 1. Her first ability is her weapon. She has two arm daggers. Her daggers are slightly faster than Reinhardt's hammer swing, but her damage is significantly lower than Reinhardt's hammer.
2. Her second ability is a shield. Laila can use her arm daggers to shield herself for 5 seconds at a time. The more damage she takes with her shield, the more armor she generates for herself. Example: A bastion puts 1,000 damage into her shield, she would generate 100 armor from that.
3. Laila's third and last ability is a flurry. She flails with both daggers in a spinning motion.
Ultimate: Laila gives out a roar and her team gains 100 armor for 6 seconds.
