I take a stuff from Crysis. Pose and body of Nightmare Moon. Background isnt mine, but I like it.
Her original guise you can see here: [link]
MLP by Hasbro.
Character by me.
Down in the bowels of canterlot a pony not known to even celestia sat in front of that machine. Left with a choice that her set her on a course from which she could never turn back. She stared at the pony shaped cradle emotionless. Encased just behind it the solution. Cybernetics. A technology that had worked to replace limbs or enhance but this moment she pursued something so much more. To merge with the nanosuit would bring with it a step closer to the thing she wanted more than anything else. Vengeance.
Magdalene-Cross was her name. Ever since the death of her sister in a church at the hands of murderers she search for an answer no other pony thought possible let alone understand. Cloaking abilities was just the start. In armor mode she could drop eight stories and walk unscathed. Maximum power the strength of ten stallions. Even her vision could change from normal to thermal with tactical options.
“Sister. This is for you” she said out loud in affirmation. As expressionless as before she set herself on the cradle and took a medical sleeping shot to the neck. Finaly gave the computer its verbal command. “Computer. Initialize merging procedure.”
A set of instruments and mechanical arms folded out from the wall as the sleeping shot had started to take its effect. Her vision started to blur and the ‘whering’ of motors was the last thing she heard slipping into that pit of unconsciousness.
A deepened voice resonated in her head only a tinge different from a normal pony voice. “Integrating new DNA profile.” The interface also started to loading with code as she sat up. What was once a glistening white coat was now a wave of nanites conforming to the muscles of her body.
Standing up she heard the slight ‘clank’ of metal to floor a mirror just in front.This was her new form. She had become “Science”
