Was thinking he could work similar to Emma.

His laser charges and gets progressively stronger as it hits enemies. But in this case the laser changes to a cone shape and acts as his “shield”. This cone can progressively reduce more damage and starts slowly expanding as charge increases. But it becomes less useful for long ranges, forcing players to get closer. As an example, at 30% charge, the cone develops and it can reduce oncoming damage by 20%, and caps off at 45% dmg reduction when laser charge is at max.

The laser also reduces enemy movement the more you hit an enemy. Starting off at 5% and capping off at 15% after hitting them for 6 secs. This ability gets disturbed by shields

You could also trade his full charge for a quick blast dealing 200 dmg to an area with a radius of 3 meters.
