These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Bloody Roar
Alternative Character Interpretation: The unborn possessing Xion in his debut can either be his sister's vengeful spirit or the unborn posing as his sister's spirit, and may or may not be the same unborn who appears in 4. You decide!
Awesome Music: YES. It's vastly overlooked due to this series' status, but some of the music is top-notch. Take the opening to 3 for instance. The soundtrack from 2 should be called to attention, as it sounds like the long-lost cousin of Guilty Gear.
It goes back to the first game. This is Uriko's boss theme.
Related to this is the undisclosed connection between Uranus and Cronos. In 3, each character fights a person that is somehow linked to them (for example, Kenji/Bakuryu fights Yugo on the last stage to prove his worth to his big brother). Cronos faces Uranus, instead of Ganesha or Yugo, who are connected to his storyline. It's speculated that Uranus may be the wife of King Orion, which would make her Cronos' mother. For the record, Cronos' story states that his mother was killed in a war along with his best friend, Jane (aka Shina), the latter of whom was revealed to be alive. Uranus' lack of an ending sequence in all of her appearances doesn't help either of these beliefs.
In fact, according to the Official Players Guide by BradyGames, there's only a five year age difference between them — their ages are stated to be 28 (Uranus) and 23 (Cronos) respectively. (It should be noted that BradyGames is sometimes hit-or-miss with the quality of their guides, some of which contain erroneous information, so make of that as you will.)
To go into detail, Uranus has most of the traits associated with Final Boss Uriko from the first game—the lightning powers, Teleport Spam, etc. From the beginning, she outclasses her foes, but upon accessing her Chimera form, her strength increases exponentially without losing speed. She can also immediately switch between her human and beast forms. Her Hyper Beast mode, on the other hand, allows her to retain her human shape, but gives her the moveset of her beast form. For these reasons, it's no wonder that Uranus is usually banned from competitive and Tournament Play.
Ryoho, being an outright SNK Boss, is no better. For one, you fight him alongside Mana (who is in her Ninetails form). Mana usually serves as a distraction, allowing Ryoho to followup with devastating blows, the worst of which is a stance which unleashes a powerful punch the longer he holds it. Should he fall, Mana sacrifices her health to recharge his, taking her out of the battle, but giving Ryoho a second wind. His Beast Form, the Dragon, is the largest of all the fighters, with tremendous range, an OHKOfirebreath attack, and resistance to flinching. Like Uranus, he stays as a human in Hyper Beast Mode, and gains the fireball projectiles of his beast form.
The Scrappy: Most of the fandom doesn't take lightly to the new characters introduced in 4 (of the four, Reiji and Mana seem to get the least flak), although this also overlaps with the fandom's hatred for 4 in general.
It also echoes what pretty much happened in Primal Fury as well since any new character there was also hated.
Shipping Goggles: Thanks to Cronos affectionately stroking Uriko's face in her Extreme/PR ending (an act that causes an awkward reaction from both), quite a few people have misinterpreted the scene as something a bit more tender. In reality, he most likely mistook Uriko in her true form for that of his mother, tying into the aforementioned Uriko = Uranus = Cronos' mother theories.
Surprisingly Improved Sequel: Bloody Roar 1 was a fairly crude mash fest with poor controls, crap A.I. with a wannabe SNK Boss that can be defeated by blocking and punch spamming, with no balance whatsoever. Bloody Roar 2 was a wonderfully elegant game, refining the engine of the first, making it easier to pick up and play, but making it nearly impossible to move spam, dramatically improving the A.I., and fixing the mechanics until you had a game that was simple to pick up yet had a surprising amount of depth, and would screw you.
The Scrappy: Many portrayals of Cronos in fanfiction often involve bashing him to no end and making him a gay, whiny, emo/snobbish brat who often is killed in various different gruesome ways. He was never really shown as wangst-ridden, spoiled, or gay either (bar the mistranslation noted in his section of the characters sheet).
The Woobie: Stun used to be a top-notch scientist at Tylon but was captured by his friend/rival, Busuzima, when he learned about the evils of the organization. He then used Stun as a guinea pig in an attempt to create the first man-made Zoanthrope. The experiment "succeeded" and mutated Stun into an insect-man-beast, unable to change back to human. The unstable nature of his form, caused every moment of his existence to be filled with pain. Stun vowed revenge on the company and person who did this to him, when the burden of his form simply proved too much for him to bear and he died bitter, miserable, and alone.
Anything in 4, from the cutscenes, new characters, crap A.I., ease of button mashing (going from it being pretty much impossible in 2, to being a way to get an automatic combo in 4), and the change to the series' image. Not to mention the negation of a good deal of the Character Development...
