This Was A Really Quick Drawing - Tumblr Posts

Well I was thinking that it was kind unfair that Selly had no especial equipment of her own, or at least something similar to other Robot-Trains, soooooooo:

Selly's especial equipment: unlike the rest of her friends, she doesn't need to add an "extra layer" when she's using her powers. Instead, she modifies her hands by concentrating a lot of energy in her fingertips. The metal literally melts and reshapes into claws, that now are sharp and hot enough to cut through basically anything.

In a later actualization, she is also able to send and receive signals through these claws, this is especially useful when changing the properties of certain machines she has made or... to mentally control other trains! When she buries her claws into an engine, and activates the "yellow mode" she will connect "them" to her own engine, and the two will function as just one train. The other train is still conscious and able to communicate with her, but ultimately she's the one in control.

She uses the latter mostly during expeditions that require certain actions to be done with precision, for example setting up weather sensors on dangerous places.

Cons:

The claws take a "lot of time" to be ready to use, at least in comparison to the rest of the special equipment.

They can be tricky to control since she has to deactivate most of the sensors in her hands before melting them down.

She has to get her hands replaced each time she uses her ability for them to have normal functions again.

Pros:

After they are set they actually are the least energy-consuming special equipment.

They come in really handy for her day to day work.

When she is connected to another train, she can make their shared energy last a lot longer than usual, optimizing most of their general functions.
