I'm sure I missed a few, but these are just the ones off the top of my head. Personally I hate Skids and Mudflap the most on the grounds that they were a part of a theatrical production and were representatives of Transformers to millions of average joes. They had a standard to uphold and they failed in the most epic and offensive way possible. Any others?
When we say Autobot, does that include any Maximal descendants too? Because if so I'm picking Nightscream.
Animated Ultra Magnus is kinda lame for what he's supposed to be. As the so called "Highest leader of all Autobots" among the Autobots in the show, he didn't do anything aside from stands there and get shot by Shockwave and die off-screen. I'm sorry, but he's just lame for me. Skids, Mudflap and basically any of the Autobots that isn't Optimus, Bumblebee and Ironhide in the Bayverse is just lame. They aren't too bad as characters, but most of them like Jolt, Que and Arcee are just cannon fodders that are just exists so that the Decepticons can shoot them.
When you are making a poll which is the worst at something and you plan to include G1 Wheelie to it, you dont need the poll at all. Its an automatic win.
No. Anyway, I'd have to go with Energon Ironhide. I mean I kinda like certain parts of Energon but not Ironhide, thats not Ironhide I don't even know what that thing is.
It's what happens when you try to maintain a naming copyright without screening the new recipient first.
Lamest would be the UK exclusive, Shitbot. He had a Universe entry in the Marvel UK Transformers comic book and got a figure in 1990 as an Action Master. All true. HE TELL ME.
