Personally, I can see Cole keep going between them as they are both his family. However, we still don't know what will happen... Bonzle already met her creator who now occasionally babysits her, Fritz and Spitz. So maybe the other two will reunite with their families...

Considering the element of Form comes from the Source Dragon of Flow, maybe they can change their form and take a human appearance. It would be interesting if the Source Dragon of Flow would walk between mortals unnoticed to observe them.

*all or nothing (not all of nothing).

I think Doc already told that, for elemental powers to be taken, it needs to be all of nothing. Meaning... the SDs need to come to a consensus about removing the powers altogether and not just a few in particular. Like... Lloyd was showed still having his element, despite Life left the council.

I always imagined that dragons with form powers could assume a human form. Like... having a tribe of dragons that normally take a human form and live like humans in order to mislead anyone that seeks them.

I personally don't think Bonzle will be targeted again... at least because of her being a spell. After all, she is the spell specifically made to open a portal to Nether-space, which only works during the blood moon. Unless... she is targeted by people who want to modify her original design.

Doc, can you answer this one question: if the Land of the Three Mountains is part of Imperium, does that mean Riyu's tribe used to live alongside Imperians before Beatrix rose to power and started to enslave dragons?

Constrictai would make sense, as it fits Frak's element of Quake and his love for speleology. Not to mention his relative that is an archeologist. Now, I thought of Venomari because it would be cool if Frak had inherited their venom, but also because Fangpyre and Hypnobrai don't seem to match.

Well... not all Venomari have four eyes... Besides, there has to be some between the same tribe that can differ from the others. The five tribes did use to be together before separating. Maybe some individuals carried out some traits from an ancestor that was from a different tribe.

I think not... It wouldn't make sense, considering his element.

I believe Frak is half-Venomari/half-Constrictai. It would be cool if he could use the Venomari venom or the Constrictai strength, but I guess he would only use them as a last resource. His elemental power is about causing things to vibrate, not just the ground, but anything he touches.

Hey, Doc, here's a silly question... If Frak is better than Arin in pie baking, would the former be able to beat Chef Grab-Barg in a pie contest (or with Arin's help).

The Great Devourer also blew up and both Master Wu and Pythor were able to survive. So it's possible that Kaalmar also survived.

I have this theory that the FSM's dragon parent is actually one of Firstbourne's first children (along with Thunderfang). Also, I wouldn't be surprise if either Motion or Energy called Lloyd to the Council of Sources' reunion so he would know about Thunderfang.

Considering the Serpentine migrated from the Wyldness, it's possible there are other tribes, either on their home realm or in other realms. However, the ones in Ninjago are the five ones (now four) that we know so well. So it's only logical to conclude Frak is a hybrid of at least two of them.
