The strongest char you fight ever.

[Azlan Sosuke]

have you fighting enemies that you consider strong, whom he?

[Gaulbetti]

What? Well, I guess Ryugen, DnF characters, Ella, Mataou Sakura, Doraemon, Teaf's characters, and Kaz's characters.

[Kazagami]

but you didn't fight them, you let cheapies and f1 button to do the works

[Octavia Melody]

Ovnunu by OMEGAPSYCHO. Both the boss itself and the eyeballs take FOREVER to kill! To quote the Nostalgia Critic: "I can eat my way through a WALL faster than I can defeat these [eyeballs]!"

[Flowering Knight]

Limiter Cut Broly.  No, I'm not saying I beat him, because I didn't, and unless I pick a character cheaper than him, I ain't gonna.

[Azlan Sosuke]

I must confess that kaixa, broly and mugetsu is a strong enemy.

[DarkWolf13]

My strongest enemies are hsienth's Morrigan, Matsutzu's WereGarurumon (MvC2 conversion), Kamekaze's Shin Bison, KAZ's Magneto, All Street Fighter Spec Ops characters... I got many more but there's too much to detail...best way for me to deal with any of them is to USE one of them to defeat the other.

 

The greatest enemy I ever faced: Onodera Ren!

[Ex✭Cᴀʜᴍ]

the most hard to beat char i have atm is.....

Goku SSJ3 by Sankity and Skullomania by Divinewolf (AI patched) 

Need to add more chars :P

[Shinzaki]

Oda Nobunaga by Rei

*shot*

[Gaulbetti]

but you didn't fight them, you let cheapies and f1 button to do the works

 

Oh, you're right. Guess I'll just revise them to the "harder to out cheap with Aaron Roulette list".

[Wargame-kun]

ogre by jun

 

yea its a cheap character but i manage to win using nanaya shiki

[Dumanios]

The strongest characters I beat without using someone exceedingly cheap would probably be Legendary Wolf Terry Bogard, Evil Ryu, and MegaMari.

[miru]

Omega Tiger Woods.

[tehdevil]

Kaz's Ryu and Ken and Chotto's Zero Ryu

[Remzy]

*inserts Pre-To's and baggy's characters and edited characters by LJH*

[Kazagami]

Oh, you're right. Guess I'll just revise them to the "harder to out cheap with Aaron Roulette list".

 

[Zemilia]

The strongest characters I beat without using someone exceedingly cheap would probably be Legendary Wolf Terry Bogard

 

IDK, I had no problem fighting Legendary Wolf Terry Bogard with Silent Storm. :P (In fact, it was a surprisingly fun fight as well)

 

Anyway: Does Nightmare SSJ Beat your ass up to oblivion Broli by Guthor counts?

If broken chars don't count; then let's just say that I had a hard time fighting this dude: Gustab Manchausen by Zelgadis

[SSBKing65✯]

A lot of characters, probably G-Tenko R. She has so many effects...

[ろくお 石田 (旗 の 心)]

which choose not to everyone.
