"Sucker-punching isn't on my skill list," he promised with no lack of good-nature. "If anyone is worth cracking in the face, they should see you coming."
He stepped forward a little and lifted his left hand, waving a few fingers of his right in the air over his forearm. Almost instantly his omni-tool flashed to life, the holographic device encompassing him from fingers to elbow. "This is an omni-tool, and it's what allows me cloak, among other things. It's technology from my universe. Most of these devices are just for analyzing data, storing media or repairing things, but the military grade ones have a number of functions used for combat or survival. Each set of abilities is tied to a specialization. Mine allows me to cloak, incinerate things, add freezing abilities to ammunition. At some point maybe I'll show you the rest of that if I can, but not as a surprise like the last one."
