    UNDERTALE is one of the greatest games ever made, and the bosses are some of the best and most difficult. But what makes the Monsters so powerful? We know that Human souls are much stronger than the souls of Monsters, but that doesn't seem to slow them down. In this episode, Austin dives deep into the Underground to investigate the history and power of Souls, Monsters, and Humans in the world of Undertale!

    When you talk about the monsters being murderous, here's the thing. The humans and monsters are already pretty racial stereotypical about the monsters. This is a crime both the humans and monsters probably committed this crime. If you saw a monster on the street, you would probably steer clear. Most of the monsters are trying to kill you for the greater good: hundreds freed. OF COURSE they'd want to kill you, not just for themselves but for there family, their friends. And besides, a lot of them don't actually want to kill you. Toriel, Mettaton, probably all of snowdins random encounters. A lot of them are forced to. And besides, with hundreds of these (7:12) and these (8:59) I think the monsters would have won.

    MATPAT! Do a five nights of freddy's: joy of creation theory! I have a small kick starter for it! So when you finish the first night you see that at the top of the news paper it says august 8th 201.... it does not say the last number but it does mean that it is more closer to 2017 than any other fnaf game but that is only the first night that means that that is a long time ago compared to when Scott's son get's his house back. I do not remember if Scott's son says it started 5 years ago, or something, when he is going to start telling you how it all happened. So yeah get to it Matpat!

    my son ordered one of your shirts from STUDIO &! US SHOP on June 18th. Despite 3 emails telling me it had shipped and sending me your inane video (3 Times!!!) telling me I'm gonna get a "free pin" shirt still hasn't arrived. This company are liars and cheats, in my opinion and your endorsement of them implicates you in this deceit. You should be ashamed of yourself ripping off kids in this way - disgraceful! DO NOT HAVE ANYTHING TO DO WITH THIS COMPANY STUDIO 21 US SHOP - OR ANY OF ITS SUPPORTERS INCLUDING GAME THEORISTS

    You should talk about how Echo Flowers work. A couple of friends and I have been putting together a theory about how these flowers exist in abundance in a place without sunlight, echoing everything that they hear. I'd enjoy hearing your thoughts on them.
    And, also, this is one of the many reasons why Flowey is my favorite character(s?).

    Theres one simple thing you missed. Asriel took charas soul to make it through the barriar. He died with charas soul, but asriel turned into flowey. Flowey had charas soul when he turned into asriel again. That meens he had another soul to use to be that powerful

    I am terribly sorry that the over-zealous fans of Undertale gives you guys so much trouble. Those kind of fans is what gives descent fans like me a bad name and treated the same as the bad kind of fans. I think the game theories of Undertale is actually really good and plausible in most areas... Except for the first Undertale theory, I just don't get it really but at least I didn't take the theory too seriously like everyone else did. Keep up the good work and maybe someday Toby Fox will see these and he'll clap his hands and say, "Congratulations, you've managed to reveal my secret in the lore of Undertale!" =)

    Anyway, cool video, very enjoyable, cheers~ <3

    Flowey absorbed 6 human souls he absorbed all monsters soul(or 1 human soul) so that means he absorbed 7 human souls.You need just 7 human souls to become a god(or in this case the god of hyperdeath)not 13.687.So there is no way that there is extra 6.687 souls.And if they did hunt humans on the surface wouldn't they used that power in the war to destroy not just the whole village but the whole human species.All of this can support my theory that i written down in the comments.Monsters were pacifist all of the time.
