You know, I felt felt like what this game really REALLY needs is some kind of alike to the "PvZ Gargantuar" AND I think I found the perfect fit!
I would suggest a late game enemy which is the "Sweeper" from the movie "Robots 2005"

I think these would add a huge tanky and slow unit that would be towering over the units, and having something like this would also make a good "Boss-like" unit for late game for variety of levels with different themes.
Lemme know what you think of my suggestion. Thank you :D
P.S. a lil bio idea bellow...
"Sweeper" - When streets are flooded with trash that not even the Big Harry can handle, that's when they send in... the Sweeper. Its presence alone scares even most of the Vroombas with mix of fear and awe as the true professional joins their ranks to do its job. Taking down this towering giant is going to take a lot of effort.
