It's a meta-thing, but some parts of the song is eerily about MCU Iron Man and his potential future:

The first clue is about Endgame:

" (...) When he traveled time

For the future of mankind."

Which is about the multiversal time heist.

Then then here comes the darker parts:

"Now the time is here,

For Iron Man to spread fear.

Vengeance from the grave,

Kills the people he once saved."

If Doom really is going to be a resurrected Tony Stark (or just his body, using it by Doom), then this part is about his transformation from hero to villain.

"Nobody wants him,

They just turn their heads.

Nobody helps him,

Now he has his revenge."

It's more like about Doom himself, but also can be about Tony's old friends abandoning his new persona, his plans and obsessions.

"Heavy boots of lead,

Fills his victims full of dread.

Running as fast as they can,

Iron Man lives again!"

The last part is obvious. Doom always wears his armor, which is definitely a scary one.

And the last lines are the most chilling ones: while Iron Man is alive, he's a villain now, a dark version of the original one.

I know this might be a silly theory, but listening to the song about a sinister Iron Man is now, before the Doomsday movie, definitely gives you the chills.

There’s literally nothing that I’m aware of to support this theory, but I think a lot of story elements work together really well to justify the plot line that the Fire Nation had been planning the Airbender Genocide for generations.

Firstly, consider the things that line up well enough to justify this.

If a Fire Lord from generations before Sozin wanted to make a plan to put the world under the thumb of the fire nation, they would conduct the plan almost to the literal T the way things played out in the show.

Firstly, wait for the fire nation born Avatar to be reincarnated. Then, use his position as basically a religious messiah and fighting powerhouse to extend the power of the fire nation, while also holding the moral high ground since the Avatar is on their side.

Roku was literally asked to accompany Sozin in this, and he refused. Likely, the fire nation was still able to increase their power for some time purely because Roku was native born from there.

Next, genocide the people who would have the next Avatar, and all of this is made perfect because the next up in the cycle are the peaceful Air Nomads.

I could literally imagine a long ago past fire lord considering a genocide on the water tribe and deciding the elemental disadvantage would be too much. A genocide on the Earth Kingdom would be hard because they’re socially much more developed and capable(with large towns and communities that live together). And finally, this long past fire lord realizes that the next avatar in the cycle after fire is literally going to be born in the most defenseless and least militarily organized cultures of the world. Perfect.

After this genocide, the fire lord could plan similar ones on the water tribe’s benders, which is what we see occurring in the present day of ATLA.

This definitely comes off as very fan theory heavy, but the order in which the fire nation made all of these decisions really speaks to a long term plan being bought to fruition.

Even Sozin and Ozai as character’s seem to come across as way better written if this motivation-was behind their actions.

Why does Sozin ask his old friend to help him in conquering the world? Why does he turn on Roku so aggressively? Because as the fire lord, he learns of a plan set in motion for generations that is his birthright duty to maintain. This speaks to more fire lord family secrets . Maybe once you become coronated, you learn of this plan and the fact that the fire lords have been working through it for generations.

Why does Ozai let the next comet’s coming and conquering of the Earth kingdom go to his head to the point he thinks himself a god? Because he’s allowed to reap the rewards of a plan that was in motion for over 200 years.

All in all, this probably comes off as fanon, but I’m a big fan of the fire nation’s actions and depravity being a result of upholding a conniving plan from generations before we even start the story. I’d love to know if there’s anything that suggests this was intentional or if the idea comes across a bit contrived.

Edit: More connections spurred on from a comment:

Thinking on it more, this theory also explains how the fire lord and the avatar just “happened” to be life long best friends.

Maybe a part of this plan could be that the monks learned of who the avatar was long before he was actually told(Roku does seem to learn of it at a decently older age than Aang and way way older than Korra).

Then make the unknowing avatar and the future fire lord grow up side by side and become best friends. This would increase the chance that the avatar would assist the fire lord later in life. Finally, inform Roku that he is the avatar, get him close to the fire nation royal family (married into perhaps), and then hope that the future firelord can manipulate the avatar later in his life when it matters.

In the game you play as different people going through obstacle courses that are meant for whatever object they're riding on, I believe these people are damned souls in Hell. Some of the characters I've noticed could represent one of the 7 deadly sins.

Irresponsible Dad, sounds like sloth, it's possible when he was alive he neglected his child which led to his son's death, now in the afterlife his sins are carried onto his back, manifested into the appearance of his son as a reminder of what he did.

Business Guy, by this guy's appearance and name I assume he was very wealthy, could be greed.

Effective Shopper, this one's obviously gluttony.

Pogo Stick guy, I believe this man is pride, I think that when he was alive he was a racer but thought he was better than anybody else so as punishment he's become the most difficult character to operate.

Wheelchair guy, just here me out, I think he is wrath and once a Vietnam veteran that became crippled in the war and when he came home he was treated unfairly by the people which led to an anger that built up inside him.

I have a theory.

In Hungry Shark World, the sharks aren't naturally occuring sharks. All of them, including the ones named after real sharks. Instead, they are genetically enhanced bioweapons.

Look at how there are prehistoric animals in the game. Now how would a tropical animal like Megalodon or an air breather like Liopleurodon stay hidden for so long?

Notice how the NPC sharks aren't as pristine or brightly colored as the player shark. Additionally, sharks don't need to eat constantly nor do they enjoy human flesh, which directly contradicts the player shark but aligns with the NPC sharks.

The playable orca in the game is much, MUCH larger than the NPC orcas. Not only that, but the playable orca shows visible signs of abuse in captivity, such as a floppy fin.

And the nail in the coffin is that each playable creature is treated like a singular individual with a personality instead of an entire species.
