Unfortunately, your suggestion break rule #5 on the Suggestion rules. I will explain now.
Count Bleck, Lakitu, Boom Boom, & Fawful are all Mario characters. As you know, on the Main Roster, we have 9 playable Mario characters. Since the Mario series has playable characters on the Main Roster, they are only allowed to have 1 rep on the Main DLC Poll. If you look through the Main DLC Poll, you will notice that Daisy is already a candidate. Therefore, Daisy already holds the only Mario rep DLC spot for the series and no more Mario characters will be accepted to the DLC Poll, unless its in favor to replace Daisy.
As for Mr. L, alternate characters are not confirmed to happen through DLC. So for now, that is out the question. Also, Mr. L doesn't carry support to be playable according to the results of our Alt Discussion Poll which closed 3 months ago.
Slippy Toad will also not be accepted for this poll. Reason for that is cause we had a Star Fox poll last year. The end results were that nobody supports having a Star Fox DLC since the series already has 4 playables on the Main Roster. Therefore, there will no longer be anymore Star Fox characters other than the 4 present on the Main Roster.
Mother Brain will also not be accepted for suggestion. Reason cause we have Samus & Ridley on the Main Roster while Anthony Higgs is Confirmed DLC. Therefore, no more Metroid reps will be accepted.
In conclusion, none of these suggestions will be approved and this poll will no longer continue.
LOCKED.
