On your walk, you found a seemingly deactivated robot sitting on the sidewalk. Since it was quite hefty and tall, it took a bit of work to drag it with you...since you obviously wanted to take it with you, for whatever reason.
Once you got it home, you tried to figure out how to..."turn it on." About an hour passed of fiddling with the bot, before you realized the oven in her chest had to be stoked. So, you opened the little gate and threw in some wood and coal, then lit it. Suddenly, it powers on, its eyes lighting with an orange-yellow glow due to the fire, small wisps of flames creating eyelashes. Unique aesthetic.
"BZZZT. CORE OVEN ACTIVATED. UNDERGOING REBOOT." Despite not having an obvious mouth, maybe it had some kind of voice box. "REBOOT COMPLETE. ENGAGING DIRECTORY FOR TASKS..."
"NO TASKS DETECTED. LOCATING DATABASE...DATABASE LOCATED. RUN PROTOCOL 'MASTER NAME...' NO CURRENT MASTER DETECTED. THIS IS AN OVERSIGHT." The robot looks down at you from her height. "UNIDENTIFIED SPECIMEN. FINGERPRINTS MATCH WITH DETECTED SCANS."
Oven suddenly paused. Rather than the whirring of gears, you only heard the sound of cracking wood and coals. Occasionally, a small ember would fling from her chest, thankfully disintegrating before hitting the ground. "SCANNING DATABASE...SAVE DATA FOUND. NOW REPLAYING LAST KNOWN SAVE DATA."
After a best of silence, the voice of Dr. Eggman plays from Oven's voice modules. "You worthless heap of scrap metal! I should have known better than to try and replicate Metal Sonic. After all, great genius can only be replicated once...oh well! Off to the Scrap Brain with you! Toodle-looooo!"
Who the heck days toodle-loo?
In any case, when the recording finished, Oven stood there silent, as if you didn't exist. Then: "...AH."
Oven stands there, like she was actually contemplating something, before she finally noticed you. Her hands fold in front of her white apron. "SO IT SEEMS, THEN, THAT YOU ARE THE ONE THAT ACTIVATED ME. PLEASE REGISTER A NAME FOR 'PROTOCOL_MASTER.''
