New Rules: Instead of rating the individual races within the race categories, I'm going to rate the races as they're displayed in the How to Play. Also, instead of a rant-type description, I'll list a few pros and cons.

Tier S (Godlike)

Characterized by high stat totals along with super strong racials, or racials that supersede the need for high stat totals.

Artificial Creation

Pros:
- Soooooo many options for customization
- Has some of the most powerful/useful racials, including the Standard Mechanics and Bio-Android
- Can switch out their attachments to prepare for ANY situation
Cons:
- Some combinations don't work together

Changeling

Pros:
- Each of their nightmare forms provide good boosts that carry over to their final forms
- Ultimate Evolution is the greatest form on the site, hands down.
- Bio Suit enhancements only add more fun to the table
Cons:
- Starting the battle in a nightmare form gimps your battle power

Majin

Pros:
- Tanky as heck, even being able to tank severing or fracturing attacks
- Candy Beam lets them get extra power by killing
- Majin Absorption allows them to comeback from being outnumbered
Cons:
- Lowered STA regen
- Their only transformation (Pure Form) is lackluster at the moment, locking them into moves and draining a lot of stamina for comparatively small benefit (Similar to Xenoverse 2's Pure Form)


Tier A (Rival of the Gods)

Characterized by high stat totals along with decent racials.

Saiyan

Pros:
- Saiyan Persistence is an incredible stat boosting passive
- Have the most transformations on the site, and can go between all of them at will
Cons:
- Zenkai requires getting knocked out and losing in a battle, which usually requires setup

Shadow Dragon (A WIP, but we have enough info about them to make assumptions)

Pros:
- Have plenty of racials, including special techniques and out-of-battle benefits
- An ultimate form that's quite easily unlocked, and can be attained right from the start in special circumstances
Cons:
Big Con - Both of these things require you to hold Dragon Balls, which can be difficult if you're not partnered with someone strong, making it a risk vs reward class


Tier B (Average)

Characterized by average stat totals with good racials.

Namekian

Pros:
- The skills given to them by their clans benefit them greatly
- Their transformation reduces damage taken as well as giving them a stat boost
Cons:
- Their only transformation locks them into certain techniques, locking you out of your chosen moves until you get out of it, preventing you from using it like Saiyans use Super Saiyan

Celestial Warrior (Kai Warrior currently a WIP)

Pros:
Big Pro - A transformation with no cost
- Unique and fun racials to go along with your transformation
Cons:
- Racials don't allow for god-like stats, lacking a god form or an end-game bonus

Demon (Races aside from Demon Scientist are WIP)

Pros:
- Demon Scientist is the best supportive class
- Stone Spit is a strong tool to remove threats for a few turns
Cons:
- Demon Scientist needs a partner, or they will be a below average fighter until they reach their final form


Tier C (Below Average)

Characterized by a lack of tools to combat evenly with the above races.

Aliens

Pros:
- Fully customizable, allowing you to create any alien character you can imagine
- Strong transformations that can be upgraded two different ways, making them potentially the best single transformations on the site
Cons:
- Without their transformation, Aliens have 0 racials.
