By dragon! Because you can.

Just because you can, and to impress your new mentor beforehand, you summon Tear in her draconic form and ask to ride her. She heartily agrees and crouches down so you can climb on top of her. In this form Tear looks like a classic western dragon, big four-legged, imposing and fire-breathing. Every time you see her like this you expect her to be guarding a treasure and sometimes you tell her this. Her reply is always that she is, that you are that treasure and that that is why she likes it when you ride her; it is easy to focus on protecting you when you are perched on top of her back.

So there you go flying off to the watchtower, headquarters to the JLA, on top of a massive dragon. You're wearing a leather jacket of the same rust red colour as Tear's scales, black military boots and city-camo cargo pants and the staff you carry has a bladed tip, making it look more like a spear then a staff.

So looking back it's not that odd that the first reaction of the watchtower's security wasn't to welcome you like a possible apprentice but to instead restrain you and lock you into a cell. The commotion your entrance made is big enough that soon enough you are transported from your cell to an interrogation room wearing handcuffs designed to disable magic.

You are surprised that the big bat himself isn't in the room but immediately suspect him to be on the other side of the one way mirror. Another surprise is the people that are in the room with you.
