'Probably' everything that ripped off Dragon Ball

Akira Toriyama's original manga is combined with Dragon Ball Z, ensuring post's volume isn't just loud, it's over 9000.

Characters

Blue Mary (debuted in Fatal Fury 3: Road to the Final Victory) vs Android 18

Retsu (Street Fighter) vs Krillin

Cloud Strife (Final Fantasy VII) vs Goku (Super Saiyan)

Sonic (Sonic X) vs Vegeta

Bit of a stretch I know, but if it wasn't for eye-piece...

Master Roshi

Everybody's favourite old perv has a very special story to tell.

Metal Slug

If random prisoner is given the opportunity to climb background (in this case lamppost), fall is broken by comically flapping arms.

Choi Bounge (The King of Fighters series) vs Fedora

It appears there's more to Freddy Krueger than meets the glove.

But SNK were just warming up.

Chung (Savage Reign)

HA HA HA!

Tung Fu Rue (Fatal Fury)

Like Street Fighter, original played appallingly.

In fact, shit didn't really click until Real Bout.

Anyway, I digress.

Monster vs Max Power

In glorious colour.

Check out Tung's Super in Neo Geo Battle Coliseum.

Damn I'm good.

For shits and giggles, this was duplicated in The King of Fighters XI.

Fists and Feet

Vegito is the result of fusion between Goku and Vegeta via the Potara Earrings.

Technique obviously wasn't unique to him, but hey ho.

E. Honda and Chun-Li (SF II)

Ryo and Robert (Art of Fighting)

Also, Fist of the North Star?

Probably.

Unofficial cameos

Street Fighter III

New Generation
The Glade of Ninjas has a few recruits, and one of those is Genda (posing as Krillin).

2nd Impact - Giant Attack
Reworked stage features anonymous dude, who could easily be mistaken for Roshi.

Super Saiyan

Minato in Jinchūriki form (Naruto)

Flaming aura is same principle, yes?

Billy charged (Double Dragon 1995)

Shadow Andy (Real Bout Fatal Fury Special)

And most infamous of all.

Sonic the Hedgehog 2 (Mega Drive)

Once the seven Chaos Emeralds are found, cheeky chappie can become Super Sonic, temporarily granting extra speed and invincibility.

Wait a minute, there are seven Dragon Balls.

Holy SHIT!

It's worth remembering that feat couldn't be achieved in the slightly different Master System/Game Gear originals.

Why?

There's only six.

Despite this incredible act of plagiarism, transformation appears regularly.

Here's how he looks during first season's final episode of Sonic X.

Birth! Super Sonic

Concluding with a nuclear bang.

Kamehameha

Take it away Goku.

Street Fighter (1987)

Remember when Ryu had red hair?

No?

Let me refresh your memory.

Takashi Nishiyama (who co-founded Dimps in 2000), claimed the Hadouken was inspired by 70's anime Space Battleship Yamato.

Titular flying fortress fires laser missile weapon Hadouho, or Wave Motion Gun.

I buy name, but hands?

Not convinced.

In 1988, Taito released obscure scrolling brawler Kuri Kinton, whose protagonist is capable of unleashing a similar projectile.

Street Fighter II: The World Warrior (1991)

Akira 'Nin-Nin' Nishitani and Akira Yasuda designed one of the greatest sequels of all time.

Ryu/Ken's signature move included a new pair of hands.

Beyond iconic.

Super SF II: The New Challengers

As much as we loved watching Scott knocking Max the fuck out, intro received a welcome makeover.

Immediately comparable to:

Father and Son

With so many variations to choose from, I've settled on two panels to base final flourish around.

Kamehameha (left) and The Super Kamehameha (right)

The following may well be innocent, but then again, that's like saying Boo Boo never took a dump in Jellystone Park.

Enjoy guys.

Castlevania: Dawn of Sorrow (DS)

Blazing Star (Neo Geo)

Contra: Shattered Soldier (PS2)

Darkstalkers: The Night Warriors (Arcade)

Guilty Gear (PS1)

The King of Fighters XIV (PS4)

Super Dimensional Fortress Macross II¹ (Arcade)

Marvel Super Heroes (Arcade)

Neo Geo Battle Coliseum (Atomiswave)

Prehistoric Isle 2 (Neo Geo)

R-Type Leo (Arcade)

X-Men vs. Street Fighter (Arcade)

X-Men: Children of the Atom (Arcade)

Finally.

Rescuing prisoner Hyakutaro Ichimonji in Metal Slug 2 paid dividends.

Assist could be a nod to SF, but whatever, Marco calls upon Shaggy in NGBC.
