The worst Omnitrix placement on an alien?

It's gotta be Eye Guy in Ultimate Alien. Like how tf is he going to use his ultimate skill when he can't open his chest eye because the ultimatrix logo is on his fucking chest. It never made sense to me. I get the idea behind aliens having their logo on their chest is done for simplicity sake but it just doesn't work for some aliens. I honestly like what OS and OV did more, where the Omnitrix logo was on different places on their bodies, it just felt a lot more natural that way. When they all have the logo and their chest it makes them feel too much superhero-ey and less alien-y, if you know what I mean.

What do you think? Which Omnitrix placement was the worst one for you?
