matscalle I actually did play it once, and if i did have a custom skylander (Not Imaginator), it would be a basic swarmling, but instead of the usual mini-shard cannon and beam cannons, it would get 5 beam cannons taking up most of its array of weapons, the idea is that its a glass cannon, meaning it does a lot of damage, but also being weak in terms of defense/health. The main thing making it a glass cannon is that on the back are 4 thrusters, each of them making up a quarter of the Swarmling’s mobility, and these would be the only damagable part of the Swarmling, each one having a small-moderate amount of health, when one is taken out, the swarmling has ¾ of its mobility, then 2/4, then ¼, and then finally crashing into the ground and exploding once the 4th thruster is taken out.
As for the amount of damage the beam cannons do, imagine 5 meter thick steel plating, it could definitely slice that easily.
I also forgot to mention it wouldn’t be any specific type.
