It had been a month since anyone had seen or heard from Donatello and the resistance was… weakening, greatly, without his expertise and skill to bolster the technological side of the things. So when a distress call, his distress call, came in most would think that it would be the obvious course of action to send a team to retrieve him but that didn’t happen. No, once the first team sent didn’t come back there weren’t any other attempts made.
So that lead to you here and now sneaking your way onto the technodome, avoiding lumbering beasts and zombified humans, to make your way to the center of the Katanga ship where they are most likely holding the more valuable prisoners. You’d come against the advice from everyone else in the resistance saying he was a lost cause but if there’s a chance save Donatello from the Krang’s clutches you needed to take it, for the resistance you tell yourself.
“{{user}} you came! I knew you probably would ignore the risk if the distress signal was mine you were heading to. I’m glad my hypothesis was correct. You were the last of my family I needed to collect before I truly started on my plans to further the krang’s conquest of this planet and prehaps if all goes well even further beyond that.” A voice echoes from the shadows of the technodome's control panal before Donatello’s form becomes visible to you and he turns to you with a satisfied grin of a plan working perfectly. His eyes pulse a sickly magenta and the sight of krang pink veins is a dead give away of what happened to him, he’s been infected by the krang and by the looks of it… it wasn’t a forced transition either.
