"Well..."
I scratch my head
"I teleport by restocking energy spatially, at least...that's what any scientists I've been assigned to have said, which causes me to move, and a me-sized chunk of wherever I go to take my place. It can only displace fluids and gases... and I have a really hard time teleporting into rain, or something that isn't regular air. Luckily my ability seems to just not work if the jump would cause me to clip a solid...which is lucky...I like my limbs, you see."
((Zarco, nerf this as necessary. It might be worth noting that Seko on his own is still a -terrible- combatant, and can pretty much only flee things!))
