I'm going to have to disagree with several of the Pokemon you have on this list.
Golurk looks nothing like a robot, but more of a statue.
What's wrong with Vanniluxe? I think he's a cute little guy, who would have though of an ice cream cone as a Pokemon? I think it's brilliant that they went away from the animal/humanoid/dragon thing they've had going.
While Reshiram looks like crap what's wrong with Zekrom? He's got a decent design, and at least looks better than Dialga and Palkia.
Bisharp is pretty cool. I think the concept of him is great, and he's personally one of my favorites.
Reuniclus is another Pokemon that I think looks great. He's not amazingly designed, but I think he's got something good going for him. I'd say he's pretty unique.
And finally Gigalith. Gigalith is one of my favorite 5th generation Pokemon. I don't understand why you don't think he looks good, he's got a cool design, nice coloring, and a good concept for what they were trying to achieve. Overall I would give him an 8/10.
Yes I have more Pokemon on this list I would like to offend, but I'm too lazy to do so, so I picked out a few of my favorites.
Why are you hating on so many of the 5th gen Pokemon? If you want poorly designed Pokemon look at a few of the 4th gen Pokemon like Ambipom. 4th gen was probably the least creative being mostly evolutions and preevolutions. Happiny is also a terrible Pokemon from the 4th gen. As well as Kriketot/Kriketune, Glameow/Purugly, Carnivine, Lickilicky and so on.
Within my lifetime, I've done a lot of walking. I started my journey walking on a little path called Route 1. Little did I know that walking down that route would lead me onwards to a road that went by the name of Victory. Just west of Victory Road, I walked up an entire mountain where atop stood a silent trainer who was one of the mightiest I had ever faced. I've walked, through sandstorms, across the hard desert of Hoenn. I've walked through pelting hail, across the snow covered terrains of Sinnoh. And now as I look back on all my travels I find myself walking across the Skyarrow Bridge of Unova. It took a lot of walking through tall grass patches to get where I am today...But it was worth the walk.
