So the article on-site is currently very lacking in content so I'm going to bump that quality up with the help of Orange Islands.
The best Pokemon is one that is obtained at the start of the game, can OHKO enemies off the bat, and loses only 1 HP when damaged. It also learns every HM, heals itself automatically, and has some neat ability to top it off. Such a Pokemon doesn't exist, of course, but this means that Pokemon closer to this ideal are the best.
The goal of this in-game tier list is to recommend a select group of Pokemon for an efficient run-through of the game. Those will be put in the Top tier. Very inefficient Pokemon will be put in the Bottom tier. Pokemon that are neither efficient nor inefficient—for example, Pokemon who have an initial downside but can eventually perform as well as High-tiered ones—are put in the Middle tier.
Pokemon are graded based on five factors: availability, raw stats, movepool, typing, and match-ups against major in-game opponents. Availability is a measure of how easy it is to obtain the Pokemon, and it ranges from very low (gift Pokemon) to very high (common "tall-grass" Pokemon). It also takes into account the part of the game at which you are able to get the Pokemon. For example, a Pokemon could be extremely good, but he would be worthless if you get him after every major battle. Raw stats affect the Pokemon's ability to KO others and to take hits in-game. Obviously, you want Pokemon with great stats, since that means they can easily KO many other Pokemon without fainting, or at least taking repeated trips to a Pokemon Center.
A Pokemon's movepool is the variety of attacks the Pokemon learns. Does he need a lot of TMs to have a good moveset? Can he learn a lot of HMs to help you navigate in the overworld? Does he learn powerful attacks of his own type? Having good TM compatibility and level-up moves is of great importance.
Typing and match-ups go hand in hand. The optimal typing gives a Pokemon both STAB on useful attack types and leaves it with little to no weaknesses. If a Pokemon has a dual typing, it should complement him both important to offensively and defensively. Typing also determines the major battles in which a Pokemon will be useful. (Major battles can range from Gym Leaders battles to Rival battles.) Therefore, it is use Pokemon with good type combinations that give them an advantage in most of the game's major battles.
Don't confuse an efficient run with a speed run. Speed runs are often segmented and recorded while manipulating luck through resets; these aim for the absolute fastest on-screen time, but the real time spent on them is much greater. If you want to play through the game in a relatively low time frame, then you’re looking for an efficient run.
A team is actually the most efficient (in terms of utility per team member) if it only consists of a single member. This tier list will assume a team size of around three or four Pokemon, however, as otherwise the list would be extremely centralized around starters and early-game Pokemon—everything else wouldn't be worth the effort.
The list of Pokemon we will be tiering are as follows:
The format you will use for submitting Pokemon is as follows:
Name: - Tier
Discuss when this Pokemon appears in a few sentences. Which gyms does it comes between? Does it come at a level where it can quickly compete with you team? How effectively can it catch up based on where it can train shortly after appearing?
Discuss this Pokemon's stats in a few sentences. Where does this Pokemon excel? Is it a Godly sweeper? A gifted wall? A strong wallbreaker? Discuss why you would use this Pokemon thank to its stats.
Discuss this Pokemon's typing in a sentence or two. How effective are its STABs at defeating opponents? Is it vulnerable to many types of attacks from opponents?
Describe this Pokemon's movepool in a few sentences. Does it have many effective movepool options through level up? Is it over reliant on TMs to function? Does it have access to useful HMs to help you traverse the region?
Break down the Pokemon's performance against the major opponents in the game. Discuss how well they can deal with each opponent in a few sentences. The major opponents one should cover are: Brock, Misty, Lt. Surge, Erika, Koga, Sabrina, Blaine, Giovanni, Rival Battle Pre-E4, Lorelei, Bruno, Agatha, Lance, Champion Rival. It is not necessary to mention any major battle prior to the Pokemon's appearance.
Discuss any miscellaneous information not covered in other sections here. Factors such as experience growth, abilities, and other lesser characteristics can be discussed here.
Please write somewhat professionally (I saw a LOLOLOL in one of the entries).
Some guidelines we picked up along the way:
- No glitches allowed.
- No trading in Pokemon from other games. Back and forth to evolve Graveler, Kadabra, Haunter and Machoke can be considered, but is not assumed.
- Have Fun!
Feel free to dispute and discuss other users submissions, but please, no flaming.
