So in my story of EarthSpark, now mainly aiming the S4, I was planning to include my Megatron's old war design after you know already what, relapsing.. yadda yadda- because you'd assume that would actually happen with him too like it did with Bumblebee but the part with Bee we are not gonna include.. or mention really. Yeah they kinda rescued him but he is hard to trust properly again with how aggressive he is like I said before on my other page about this.
The Terrans may also like that alt mode he has, But then again he would probably scan an new alt mode again because he's on Earth and where is the point in being a Cybertronian Tank now if there is no war or anything.. plus it looks kinda out of Place to have it on Earth with the Design it has unlike Shockwave's own. But he did keep it again for a little while but then again also the damned collar he has to wear made him unable to tranfrorm either for a while, so basically limited transformation as if he is just a prisoner.
Hashtag personally loved that alt mode he has, then Thrash was terrified because he was paranoid he will get shot at any time Megatron was there of if they were with him- And yet his Fusion Cannon was also taken away somehow and it's in Wheeljack's lab somewhere. Others weren't as sure either about him trying to be good again really.
