Ohm

Ohm, nicknamed Owen , is a decommissioned dinosaur robot meant for physical combat. They lost their wings while fighting and are now too old to move and function like they used to. Ohm can't get replacement wings from their manufacturers as they're no longer of use to the organisation in question, but they are allowed to roam free in society. They still have the capabilities to kill, but they tire easily, would get arrested, and don't desire to do so regardless. Ohm can change their body (like a Transformer) into an anthro form (good for tasks that require a prehensile grip) or a raptor-like non-anthro form (for more movement-based tasks).

As a retiree, Ohm just wants to live a calm life and make some friends even if they still present quite intimidatingly.

They got the name "Ohm" during their service, and it isn't their creation-name (which would be more like a serial number), and now they've received the nickname "Owen" as an even more casual name.
