Tangrowth is one of the best physical walls period. With a base HP of 100 and base defense of 125 it can eat any physical hit you throw at it and fight back with its respectable 100 base attack and 110 base special attack. Not to mention its regenerator ability.

It has the standard moves you'd expect from a grass type wall (leech seed, giga drain, synthesis, toxic, sleep powder) but also some other useful moves in knock off, block, and worry seed.

Its base 50 special defense is really its only downfall, and it even gets amnesia to counter it.

9.5/10

Next up is Cradily

Cradily is one of the best grass types one could ask for. Rock and grass individually are two of the worst types out there, but together, they have very few weaknesses: Steel and Fighting. Additionally, it's defenses make it the only great grass tank other than Ferrothorn. Overall, Cradily is an amazing Pokemon that deserves a 9 out of 10.

Next up is Dialga.

Dialga, as most of the legendaries, is overpowered as hell. Only speed falls form the three digits, and even then it stands at 90. Attack stands at 120, same as Defense, while Special Attack raises to 150. 

Let's take a look at the movelist: 12 damaging attacks out of 13. Out of those, 7 receive STAB. Not like they are overly powerful, only Roar of Time is above 100 attack and Iron Tail has exactly 100 attack, but recall its attack and special attack stats, which coupled with STAB make any 70-80 attack a fearsome offense. 

About defense? Well, it probably has two of the most resilience types out there: Steel and Dragon. Separately, they both have 3 weaknesses, none of them shared though. After combining both types, we get only two weaknesses and one immunity. Putting those aside, we have six types which deal the base damage, eight which deal half, and one which deals a quarter. Add its stats to the mix, and you get a massive wall to surpass.

Legendaries are both overpowered and overrated. 5/10, and that's only because I'm feeling generous.

Next up is Crawdaunt.

Crawdaunt is a pretty underrated pokemon that an actually dish out a lot of damage if you invest in it correctly. It one of few pokemon that have access to highly coveted ability, Adaptability. Top that off with STAB moves like crabhammer, waterfall, crunch, or aqua jet (for priority purposes) you will be doing massive amounts of damage to unsuspecting foes.

Although Crawdaunt has a decent movepool and an incredible ability, its stats leave much to be desired. Crawdaunt's bulk is glass thin at best (with the exception of a decent base 85 defense). With only 55 special defense and base 63 HP, a strong grass, fighting type move will finish it off pretty easily. Its regular level up movepool doesn't have a lot of useful moves, so it would be best to teach it stronger moves like waterfall from HM, and Dragon Dance/Aqua jet via egg moves. Overall, I rate it a 6.5/10.

The next pokemon to rate is Rampardos.

Rampardos is a pretty cool pokemon, in my opinion it isn't exactly strong but it looks sick. The blue and grey color combo is amazing and the spikes make it look even better. So for a grade? 8/10

Next Pokemon to rate is Togepi.

Togepi is one of the cutest pokemon out there, however it's stats and the fact that it has to be at max happiness to evolve make it a pain to have on your team. It's fully evolved form Togekiss is a great pokemon, however Togepi itself isn't really worth using without the exp share. I'm giving Togepi a 4.

The next pokemon to rate is Torchic.

Torchic has an extremely simple design and is a pretty solid fire starter all around. Its best stat is its special attack (70), and all of its other stats are all below 60. Its defenses are rather frail (even for a first evolution pokemon). Torchic can learn quite a few useful egg/move tutor moves including Night Slash, Last Resort, and Heat Wave.

Overall, Torchic has a lot of potential throughout its evolutions. With good investment in attack and speed, you can raise a terrifyingly strong Mega Blaziken if you choose to. With that in mind, I rate Torchic a 6/10.

The next pokemon to rate is Typhlosion.

Typhlosion is one of the better fire type starters out there, though it's stats are similar to the far better Charizard. It's pure fire typing makes it kinda bland compared to the other starters, and Typhlosion's moves won't blow you away either. Overall, Typhlosion is a pretty good pokemon for gen 2, but there are better ones out there. I'm giving Typhlosion a 7 out of 10.

The next pokemon to rate is Xatu.

Xatu is not the best Pokemon but does have some usability if correctly utilised. Its stats are fairly mediocre (65-75 range) aside from its special attack and speed (at 95)  which while not extremely good is alright. It has a pretty nice ability (especially for competetive purposes) in magic bounce and does have a fair bit of move pool variety. So while I think there's better options, it can still be used. I'd rate it a 6/10.

The next Pokemon to rate will be Lickylicky.

Lickylicky is easily the worst of the gen 4 pokemon that were evolved forms of previous gen pokemon. It's still got poor attack and special attack, it's defenses aren't that great, and it's slow. Fortunately, it's got some interesting moves such as Power Whip. Overall though, there are better pokemon out there. I'm giving Lickylicky a 6 out of 10.

The next pokemon to rate is Yanmega.

Very, very underrated/underused in my opinion.
Solid Pokemon if used correctly. Bug/flying doesn't help it too much, but it's certainly not bad.
It's moves aren't the best. However around 40+ or so, it gets good moves, like Slash, U-Turn, Air Slash and Bug Buzz, which have a good amount of power, especially for the latter being bug moves. It can also learn a good variety of TM's, which help it.
It has really good base stats for a bug type. At 86 HP, it has the highest of all bug type Pokemon, it's best two stats are Speed and Sp. Atk, which are really good. Overall, in the stats department it's doing insanely good.

Tinted Lens and Speed Boost are pretty good abilities, so that helps. Frisk is a hit or miss, depending on your play style.

Overall, it gets an 8.5/10 from me. Not the best choice, but it can be really good in my opinion.

Next up, Absol.

Absol is easily below average in more than one aspect.

First of all, stats. It does have an impressive 130 attack, but that's all. The other stats are at most nearly half that value. With 60 defense and special defense and 65 HP it's not like this Pokemon is made to last long. Also, 75 speed can easily be surpassed, so it doesn't guarantee the first hit either.

Then, we have the movelist. It learns a ton of attacks, but only four of those will ever receive STAB. Still, there is Night Slash there, and also Sucker Punch, which are its main weapons. The rest are non damaging or belong to the Normal type, with notable exceptions in Detect and Psycho Cut.

Last, but not least, abilities. Pressure isn't that overwhelming, and Justice is absolutely rubbish, who the hell would attempt to hit this Pokemon with an attack of its same type. Super Luck does give it an edge, even more if combined with Night Slash or Psycho Cut, but then again you will have to survive the enemy assault to have the chance to attack.

I don't think Absol deserves more than a 4.5/10. Good attacker, but lame on everything else.

The next Pokemon to rate will be Tropius.

Tropius is easily one of the worst grass types out there, mainly because of the fact it's also part flying. it has way too many weaknesses to be useful in any way, it's stats are horrendous, and it's moves aren't very good either. If you're looking for a decent grass type, then you should look elsewhere. I'm giving Tropius a 2.

The next pokemon to rate is Vileplume.

Vileplume has a really solid typing that has useful resistances including: electric, grass, water, and fighting. Its typing is a double edged sword however, because it does pick up common weaknesses to fire and flying. 

Stat wise, everything is pretty well distributed. It has an average HP stat of 75, followed by strong defenses of 85 and 90 respectively. It also has a usable special attack stat of 110. The only major hindrance in its stats would have to be its crippling base 50 speed. But that can be somewhat overlooked with its ability chlorophyll. 

It does get access to quite a few useful moves that mainly fill the role of status/support moves. Giga drain and moonlight are both pretty staple moves in terms of recovery, but it also has access to decent special attack type moves varying from sludge bomb to grass know and energy ball. 

Altogether, Vileplume is a bit underrated, sure there are pokemon that fill the same role better, but Vileplume has fairly good stats and a good movepool to make use of. Not something you find in every support/ specially offensive pokemon. I rate it a 7.5/10. 

The next pokemon to rate is a personal favorite. Chandelure.

Chandelure has an interesting type combo: ghost/fire. It has incredible special attack. It's defense and special defense are alright, but it's other stats aren't too impressive. It can learn a nice variety of moves as well. It's the best fire type from gen 5, but there are better fire type pokemon in the series such as Charizard. Overall though, I'm giving Chandelure an 8 out of 10.

The next pokemon to rate is Pachirisu.

I don't know a lot about Pachirisu, as I've only seen it a couple of times on the anime on TV. So, based on what I know, and my opinions, I will rate Pachirisu a 8/10. This is because I like Electric types and small-animal-related species.

Next Pokemon: Raikou (Raikou was one of my overall favorite Pokemon.)

With a high speed, a high special attack, and a decent attack..though lacking I think in defenses? I'd give it a 4.1 out of 5 due to my inferiority of electric typing and my skills. I'm a highly skilled trainer but a low end Electric typer.Now for the next user to rate....Rate the pokemon Cydaquil, he's my favorite!

Cyndaquil's the best starter to come from gen 2, however, it's nothing compared to the other fire type starters from gens 1-4. It's pure fire, which makes it kinda bland, it's got good speed and special attack though. It's got some interesting moves it can learn such as Eruption. Overall, Cyndaquil is worthy of a 7 in my eyes.

The next pokemon to rate is Lucario.

I think almost anyone can say that Lucario is probably overrated, right up there with Charizard, and also in the same way.

Lucario is not a bad pokemon, but it's obviously not the next best thing since sliced bread. It seems to be very solid in the game itself, as well. It's a pretty fast attacker, with a typing that can be hard-ish to crack, with the additive steel typing giving it better resistance against Psychic and Flying, the two types that are most likely to speed sweep Fighting types. Of course, this does leave it open to bulky sweepers, if Lucario can't OHKO before the attack.

I rate Lucario 8.9/10 (minus 0.1 because I hate having to deal with his aura boost in Smash 4!)

Next pokemon to rate is Aggron.

Aggron isn't any less useless than Golem for example. It's atrocious special defense and speed make it an easy pokemon to bring down. It doesn't matter how good your attack and defense are if you're supper slow and special attacks pretty much always one hit KO you. There are way better pokemon out there, even in gen 3. I give Aggron a 3.

The next pokemon to rate is Malamar.
