Basic design, but at the same time his eyes are so commanding and characterized, they strike fear into anyone who sees them.

 

As for why everyone thinks the original 151 are the best, it's simple: Because they are. Obviously nostalgia is a factor for some of us older users, but take a look at the designs. They are so unique compared to what you see after. It's like they stopped trying after the Orange League, because they knew the kids would like Pokemon no matter how bad the designs get, and to keep the games going with new ones.

Whenever I think of the original 151, I get this "rough" feeling. You know, all the Pokemon were tough and badass in their own right. When I think of the ones after that they all get like... puffy and... not tough. They try to be tough, but come off as jokes...

 That's not to say they ALL suck after 151/251,  as  I've seen some cool designs. There are just some though where I think to myself "Stop raping my child-hood plz".
