Any champions Dominant in Early and Late Game that are easy and uncounterable?
EDIT: Thanks for the suggestions. They work, but not with brainless teams. I got my champions and I will post a thread why they are and who they are. Stay tuned if you wish to see my suggestions. I changed my core gameplay to make them work, but they did good.
Tryndamere, Master Yi, Malphite.
Depends on your style and what rank you're at. Each rank has it own set of champs that's considered overpowered and that helps you climb. Example; if you're bronze and you main support, your best bet is probably blitzkek. Platimun and you play JG? I believe Hecarim does well.
Although be warned, this makes the game very boring.
But serious

This is not just me being biased, 
is extremely strong in both phases of the game.
The only trade off is he is slightly harder to learn the some other easy to play champs (Ex. 
)
But his poke in lane is great, your q is an amazing tool for harass along with your w, his e is a great combo opener or disengage, and when team fights start to breakout, he just needs to land one combo and a fight can be swayed heavily, his true damage is super high late game, and can shred tanks if fed enough.
Aside from that, some others i suggest are: 
any splitpusher
Land a Q. Profit. GG.
