Gobboz the plural form of "goblin" iirc.
Anyway, this is why TF2 is Buddhist:
There's a fat bald guy who's jolly, like Budai, except his fatness and baldness causes him to become associated heavily with materialism and worldly pleasures from a western perspective.
There's a drunken immortal with a magic sword that eats ghosts, like Lu Dongbin. And though Lu Dongbin is enlightened and has some of the supernatural attributes of a buddha, he may be misconstrued as one, but a Westerner would have flanderised his association with Drunken Boxing and not realised that he was, in fact, a Taoist figure.
Soldier is what one would mistake for Bodhidharma, a person heavily dedicated in a dogmatic way to a single philosophy they believe heavily in. For Bodhidharma, that would be the Buddha, for Soldier, that is America. They both do insanely painful things to serve their philosophies. Soldier blows himself up to fly to higher places, Bodhidharma cuts off his own eyelids and turns them into tea leaves. Soldier is also brags about his grandfather (Likely himself in a past life, the way reincarnation in this game works) who invented the art of fighting, and then perfected it, so that no man could ever beat him, in the same way that, when exercising at Shaolin Temple, Bodhidharma created the movements that would become Shaolin Kungfu.
Pyro, as master of his own personal plane of existence that has vague influence on our own, is most certainly a buddhist-appropriated deva. But which one? Probably Yama. This is where the dynamic between the eastern and western views is sort of pointed out and explained. Yama himself views Naraka as a system where souls learn by suffering, and learn how to detach themselves and overcome suffering, the hard way. To Yama, Naraka is indeed a happy place and a learning process for younger essences that are, in comparison, babies. (Fairy wings optional) but to Westerners, Naraka equates more to a nigh-eternal hell where suffering is graphic and has very real and horrible bearing on their In-Hell existence.
I haven't found a match for the others yet, but Sniper is probably a monk, portrayed as a one-track-minded hermit stereotype who stays in one place all the time, not unlike a critical stereotype of Buddhist monastic practices. He may be Siddartha himself, considering one of the more famous images he's associated with is the shocking sort of statue that features his starved/mummified state from meditating under a tree for so long. The sniper, similarly, is also portrayed as a wiry man of questionable sanity, and his melee options tend to be weaker than the other classes.
The sniper and medic are capable of sneaking around and healing people, common things associated with religious miracles, and there are probably other figures I'm misconstruing here.
They're all ethnic stereotypes, but not racial ones (similar to how there are a lot of stereotypes attributed to Buddhism, but it's widespread enough that it's more like calling out the the stereotype of philosophies, rather than races) they all perform various sysiphean tasks in order to achieve a nebulous goal, much like the quest for enlightenment, and gaining wisdom (Often misconstrued as "Intelligence") is thought to be more important in Buddhism than it really is. The message is bogged down by the empty violence and commercialism (Hats and items) surrounding it, much like real Buddhism is offset by the tourist destinations and warrior monks.
TF2, in its parody of Buddhism, doesn't stop there. In fact, by playing with Christian, Euro-pagan, and Native American themes as they relate to a stereotypical 50s-60s setting, it becomes less about calling out people for their broad generalizations and in fact becomes an affectionate call for people all over the world to be more culturally aware, which is what Buddha would've done. Probably.
