The CW (ended 2011)
Fine, fine. *gives medal*
I'm re-watching the Jack Vs Carly duel, and, Jack pulling the Savior Dragon reminded me of a duel i had today, field: empty, hand: Caius The Shadow Monarch (lvl 6), he had two Gladiator Beasts, of which one had 2100 ATK, and also an Arcanite Magician who had used it's effect already, another attack and i would die, then, i drew, Brain Control, i took his 2100 beast, removed his Magician, and attacked his other beast to win! It felt so epic!
(1.) My "Best Dragon" List (+ Power Tool Dragon):
Stardust Dragon (my vote)
Red Archfiend Dragon
Black Rose Dragon
Ancient Fairy Dragon
Power Tool Dragon
Kind of generic, but I'm sure most people would be having Stardust Dragon as their favorite and Blackfeather Dragon as last.
(2.) Dragon Card Gathering:
The Crimson Dragon could either have limited ability to see in the future or could sense Yusei's father, Rex, and Roman messing with the Ener-D and fearing that the Earthbound Immortals could use that to free themselves, it sent the dragons it could to help contain the Ener-D Reactor in the forms of cloud (Ancient Fairy Dragon was more of a blank but Crimson Dragon probably still gave it the ability to be used to seal the Ener-D Reactor until Ancient Fairy Dragon could get into it). How Yusei's father found them we don't know, Crimson Dragon could have just dropped them in front of him and persuaded him use them to seal Ener-D Reactor with them (The choice to shut off the Ener-D Reactor was still Yusei's father's idea, Crimson Dragon just gav ehim the tools to do so). That's the theory I could think up anyway.
And as for Pearson having Blackfeather Dragon, I'll get to that in a second.
(3.) Blackfeather Dragon & The Fifth Dragon:
Let's first clear one thing up: Being in the anime there are a few cards which are one-of-a-kind, Blackfeather Dragon was probably one of these cards and Pearson found it. Now here is where things split:
Theory 1: Blackfeather Dragon is the fifth Dragon and Pearson "found it" when it was looking for a fifth Signer as Roman had given-up his Signer privileges. The Crimson Dragon meanwhile send Stardust Dragon, Red Archfined Dragon, and Black Rose Dragon (as well as an empty Ancient Fairy Dragon) to deal with the Ener-D Reactor. Blackfeather Dragon sensed something in Crow but until they can get the actual mark from the Goodwin brothers, it had to lay low and went to Pearson and persuaded him to keep it and give it to Crow when Crow got his mark.
As for why Luna saw a Power Tool Dragon-esque dragon, being it was a half prophecy/half dream Luna's subconscious filled in the fifth dragon as she only knew four of them. So now she needs a fifth dragon to fill the slot and the only other dragon she knew personally was Power Tool Dragon. However having a highly mechanical dragon in the past would probably have been a bit too jarring so her mind made Power Tool Dragon more organic by replacing its metal with muscle.
Theory 2: Power Tool Dragon was the fifth Dragon but Crimson Dragon kept it behind when it sent Stardust Dragon, Red Arhcfiend Dragon, and Black Rose Dragon (+ empty Ancient Fairy Dragon card) as the fifth Signer had turned on them and it doesn't want all 5 Dragons near a Signer as one of them is for that Signer (and as long as the other Signers weren't chosen, it didn't have to give out the dragons just yet). When the other Signers were chosen, Luna's Dragon, Ancient Fairy Dragon, was MIA (both itself and its card) so the Crimson Dragon, now having assigned Dragons, sent Power Tool Dragon to protect Luna until she got Fairy Ancient Dragon. However Crimson Dragon just couldn't give Luna a dragon so instead it gave Power Tool Dragon to Leo. Power Tool Dragon took on a form of a robot to fit into Leo's deck and since then has been protecting Leo and Luna. In addition being Leo is a sibling of a Signer he was in the danger zone so Power Tool Dragon was also protecting him.
Now when Crow became a Signer, a robot Dragon with a Blackwings deck doesn't make sense but a Signer still needs a dragon. Then suddenly, Crow was given a dragon. So now with a Dragon, the Crimson Dragon made Blackfeather Dragon into the new fifth dragon. As for Power Tool Dragon, I'm sure it has a few ("colorful") words it wants with the Crimson Dragon.
