Yes, I question about Timothy/The Pulverizer/Mutagen Man.
What if he didn't get mutated into Mutagen Man? I honestly think that it would of been good if he didn't. Why you ask? Well don't you think that Timothy's past and character wasn't explained enough despite the fact that he was annoying, stupid, and a interference to the turtles? I think if he stick around longer, he would of been some kind of funny comic relief or/and a running gag.
I also like to know, since he's a teenager, where does he go to school? Did he go to April's school? Did he had friends or had any hobbies? And most importantly, WHERE THE HECK is his parents in all of this!?!? I'm pretty sure any other parent would be worried as a bitch if their child was missing for months!!! At least with April they provided that someone should be watching/being a guardian for her (she's staying with her aunt), but with Timothy, they didn't explain anything like that at all. He's just missing and it seems that no one notices or gives a dam.
I think the reason why the writers didn't include this is because it didn't have anything to do with the main storyline (just like April's living arrangements), but it's still stupid. I feel like that his life should of been more explored. If they wasn't so much in a hurry to mutate him into a mutant, then maybe his life would of been more explored than it was. They could of even made him a mutant in later season OR made someone else the mutagen man, but no. He has to be a insane TMNT fanboy who's annoying, stupid and gets in the turtles way of their missions. And if Donnie doesn't find a cure, then that's all he would be remembered by: An unlikeable teenage boy.
I think Tim could of been a great character (and maybe a funny one) if the writers didn't make him the way he was. I don't know if it was meant to be this way or not, but it still sucks.
