Max is The Avatar.
- Remember in episode 1, when Max puts on the cap for the first time, a blinding flash of light happens, and SkullMaster's crystal lights up? Remind anyone of the light that shone in all the temples the first time Aang enters the Avatar State?
- Essentially, my theory is that one of SkullMaster's evil deeds way back when was to wipe out all traces of the Avatar in the world, so that by the present day no one remembers he ever even existed. He also wiped out bending. Max COULD bend all four elements, he just isn't aware of it so he never tries.
Max's parents are divorced.
- In Tar Wars, there's a brief gag where Norman has no idea how to address Max's mom, eventually defaulting to "Mrs... uh, mom." Which makes no sense, as he has every reason to know what Max's last name is — unless, of course, Max has a different last name from his mother. Specifically, his dad's. Of course Norman would know not to address her by her ex-husband's name, even if he couldn't remember what to say instead.
Virgil is not the only Lemurian left.
- Well, just think of how there's usually more than one survivor when disasters hit human settlements. Skullmaster had to have missed more than just his "old friend"...
- At least one Lemurian survived and was later adopted by a family of cryptozoologists.
- Don't forget that Skullmaster is also a Lemurian. That's not a guess, it's stated several times in the show.
Expanding from above, any other remaining Lemurians do not help Virgil because they blame him for their civilization's destruction.
- Not everyone's going to believe in a prophecy that foretells the end of their world, and generally those sorts of things don't come true. Easier to blame the teacher of the guy who did all the damage rather than believe in something so farfetched.
Skullmaster's unseen master is Black Hat.
Skullmaster and Virgil's appearance...
- Whatever magic caused these two, and one would assume other Lemurians, to live for 10,000 years, also changed their physical appearance to match their personalities. Virgil is a wise thinker and ended up as a fowl. Skullmaster used to look like a normal human, but there was darkness in his heart that Virgil overlooked due to pride. Then when whatever magic gave Virgil's student immortality, it also altered him to look monstrous, because of his black heart, and he became Skullmaster.
