Beast Hunters Skystalker comes to mind. Barely a transformation, and just really lackluster compared to the other Predacons in the line.

 

FOC Sideswipe was a pretty awful figure. I too only bought it for the big ass gun. The black eyes didn't help this soulless figure..

 

In my case about 90 to 91% of the Animated line sucked,they all looks so disproportionate either they were tall and skinny or short and dumpy,very few of them were halfway shaped accordingly,so out of all the lines in the past 32 years by far Animated was the worst in my opinion.

But if I have to choose the #1 worst figure that honor would have to go to Supreme Rollout Optimus Prime,back then I still remember my Walmart having about 10 or 12 of those for months,and even marked down to less than $20 they still didn't sell,finally I found out from my friend that worked in the toy department and she said they boxed them all up and sold them to my local BigLots,which they eventually sold there for like $10 apiece that following Christmas.

But I advise anyone to stay clear of Supreme Optimus,that was by far the ugliest and most useless Transformer ever produced,I swear.

 

Transformers: Prime deluxe class Airachnid. She exists in my collection just because of her awesomeness in the show. The figure is terribly disappointing next to her other deluxe counterparts from the line such as the Vehicon and Ratchet.

 

That I currently own? Tough call. If I loathe a mold or figure that much, I'll take it back to the store and get my money back.

From what I still have right now? RTS Grapple since comes with no accessories and his hands are useless. I keep hm for completeness' sake. Also, Generations Roadbuster. The weapons and even the wheels won't stay on, and he's kind of ugly.

 

Because I never owned Supreme Cheetor!

 

I've chosen one: that Beast Machines Nightscream thing.
