maybe some were supposed to be after SF3 timeline if they are still alive?
You really have no problem with Ken having his classic Gi and haircut in SFIV, to having a completely different hairstyle and updated outfit in SFV, back to classic Gi and haircut in SFIII?
I really donât because he is still the same exact person with his hair styled differently (but similar length) and wearing a different top.
Why should he? Have you never changed your hair or clothes?
It could be his wife buying/washing his clothes. Man buns might not last long as a fashion.
Thereâs no reason to over think it. If you really need an explanation.
SF3 was released what? 15ish years ago. Pretty close to SF2 so the changes werenât that great. SF4 comes along and its kinda a reboot so people are happy to see classic looking characters. SF5 comes not long after SF4 so to differentiate a few tweaks are made. Characters are still recognisable but ârevampedâ enough so people arenât thinking âsame old shitâ.
If you really need a canon reason for KenâŚ
Alpha, young Ken has long hair. SF2, Ken cuts hair. SF4, Ken likes haircut. SF5, manbuns are in and Ken gets a UA sponsorship. SF3, Ken looses sponsorship and manbuns are out.
No problem, here dude
i add Elena too
Why does Elena have feathers instead of hair?
Akuma has always had a red aura in his intro.
Red aura, but his Ki manifestation (fireball and the ground spikes) were always purple, same for the Raging Demon hit animation
SNH is a sister power to Psycho Power hence the purple flames. Bison also has a red aura in some of the anime prologues/epilogues of SF4. So Akuma having a red aura but purple flames as a physical manifestation of his power isnât unprecedented.
why is evil ryu on SF4 always have the aura always on?
Same reason why Oni constantly emits the blue aura - SnH is out of their control so their Ki goes crazy all over the place, while Akuma is still somewhat in control of his mind and the aura only appears when he prepares a strong attack (e.g. any of his SF3 supers)
Just sketched braids 
There is a character for maniacs, huh.
Heâs Thunder Hawkâs father.
A hero of the Thunderfoot tribe.
Itâs said he fought against Lord Bison in the past.
Name: Arroyo Hawk
Height: 212cm
Weight: 140kg
Blood Type: O
Birthday: Juni 30
Home Country: Mexico
Favorite things: Clear water
Dislikes: Lies, alcohol
Father of Thunder Hawk.
A virtuous person who wonât forgive a lie.
Heâs always fought only to protect the sacred soil of Thunderfoot tribe.
Doesnât like useless fights, nor vengeances.
It seems he was a grappler!
Why couldnât Seth and Elena look that awesome all the time?
Arroyoâs bio makes it sound like he survived the fight with Bison. However I feel thatâs unlikely (cuz PSYCHO POWAAAAH!). Itâs good to see them giving some shit about Hawk though.
Whoa, liking Arroyoâs design, I was worried if we ever saw him heâd just be a slight alteration of T. Hawk.
edit: @Daemos yeah when I first read it I couldnât tell if he was still alive or they made a tense error.
6â11.5" 308lbs, well we know where T.Hawk got his size from.
Clearly Shadaloo acknowledges the fight but omits the detailsâŚ
Really? Cause I feel like heâs exactly that.
First time I saw the picture I was like âIs todays article an alt costume for T. Hawk?â
Well the statement âhe was a grapplerâ suggests that he is dead, but not necessarily dead because of Bison.
These bios wouldâve been perfect if they had a âWhere are they nowâ stat to fill.
