Super Smash Bros. Wii U and 3DS Discussion

 My Confirmations

Dr.Mario does not require any intensity. I was doing all my Classic Mode runs at 4.5 for a long time, and the only three characters I did not unlock without increasing it are Ganondorf, Bowser Jr., and ROB.

Ganondorf and Bowser Jr. require 6.0 or higher intensity. It's the intensity that allows Master Core to appear if you choose to fight both hands at once instead of just Master Hand, however both hands are not required to unlock any character.

I'm not so sure about either of those Jigglypuff requirements. I don't remember what exactly unlocked her for me, but I never used Charizard in Classic Mode. In fact, the only Pokemon I did use was Greninja and I unlocked her after. It may just be a usage requirement, and not Classic Mode. I honestly don't remember.

ROB requires Game and Watch on 6.0 or higher.

 Spoiler

Thanks. When you ssay 'you unlocked her after' do you mean right after using Greninja or do you mean way after using Greninja? There's a requirement that says you have to use a character with custom moves and I don't know if that one is true.
