Super Saiyan 4 Gohan (Boo arc) vs. Evil Boo

[Six Trails]

Who wins?

 

[SSJ2]

Boo.

I'd like to believe that Gohan's powers going well beyond their limits is more than a 1.4x boost or so.

 

[FutureProtagonist]

Definitely Boo. Potential unlock isn't special, Elder Kaioshin's ability is.

I'd see him reaching SSJ Gotenks-post at best.

 

[Let's Go Fearless!]

Beyond to its limts > Potential Unlock

So Boo wins.

 

[Captain Cadaver]

From the way Elder Kaioshin emphasised on the "Beyond" natural limits part, the ritual power up should be a great deal more than the character's limits. I'd give this to Boo with high difficulty, though mid diff if he's smart enough to utilise his skills efficiently.
