"The Queen/Drone combination upgrade." Samus selected from the list. Still in her Drone upgrade form, she had discovered that the Drone upgrade was compatible with the Queen upgrade, and was curious as to what would happen. She also for some reason felt like it would be an improvement, like what she was meant to do
She took the upgrade from the machine and inserted it into the upgrade slot, waiting for the changes to begin.
Immediately, Samus' hips and rear began to widen, the fuzz on her thighs thickening as she nearly doubled in width, her breasts growing a few sizes to match. There was a cracking sound as her carapaced feet changed, the flat heel changing into a natural high heel, giving Samus a few extra inches of height as she adjusted her footing, walking on it perfectly naturally. The black chitin itself on her arms and legs few shinier and glossier, as the antennae on her head grew a bit longer, while her clothes began to change as well.
The leotard of her suit began to become thicker, going from skin-tight to a silky fabric, material growing at the hips to drop down into a dress, reaching her ankles as it took on the same black and yellow striped pattern as the rest of her dress. The stitching on her dress grew more elaborate as a hole was opened to allow her stinger to be exposed from the back, the stinger itself growing larger and longer. The dress became high-necked, her exposed cleavage being covered up as a large, octagonal yellow broach was placed on her breasts, two smaller versions being pierced through her ears as earrings.
As Samus patiently waited for her changes to end, her face began to change as well, her lips plumping up as they gained a similar layer of lipstick to the queen upgrade, light yellow makeup and mascara adorning her eyes as her eyelashes grew longer and more appealing. Her hair grew as well, trailing down to just below her stinger. On her head, a pointed crown formed, encrusted with the same jewels as her earrings and broach, her symbol as a queen.
Believing her changes to be complete, Samus began to walk towards the mirror, her hips shaking through the dress, when she stopped suddenly, a rumbling coming from her belly, as the final stage of her transformation into a queen bee began. Her belly began to swell outwards, the dress growing to match, filling with hundreds of eggs, ready to populate a colony of her own. As she reached the size of full term with twins, the size of an early stage in her pregnancy as a queen, inside the eggs were actually artificial, the upgrade still being reversible keeping the eggs that way. Were she to keep the upgrade for long enough, they would be made natural. Cradling her belly in her rigid hands, she continued her walk over to the mirror as her mind was altered, a confident smile going over her face as she realised her duty as a queen.
She took a look at herself, going over the changes that had been made. She was much wider, with a large belly under a yellow and black striped dress, her stinger and antennae much larger and longer. Her wings could no longer support her weight in flight, but she realised that she didn't need it.
"A perfect body for my role, far better than that common worker's body." Samus said, appreciating her new body for her new role.
