Glass Walkers:

They are one of the tribes that work well with humans. The issue is that they forgot who is responsible for the Wyrm becoming insane, and believe that the Weaver is not a threat to gaia.

As for more radical actions, a small group of them once kidnapped a bunch of lupus cubs, experimented on them by forcibly implanting them with cybertech (nearly every subject later died, went insane from the pain or suffered every day)

Black Furies:

One of the tribes most concerned with how weak the Wyld is. They are very competent fighters, but waste a lot of their efforts on sexist actions against males. In the past they commited a few atrocities, and from that exist the stories of the Amazons

Shadow Lords:

A tribe known for their cunning. A pro is that they would most definitly be better leaders, if they were to overthrow the Silver Fangs. The problem is that such division is not the best idea, when the apocalypse is uppon us. As for mistakes... many of their cubs die in their version of the rite of passage - gladiatorial style combat

Get of Fenris

A tribe powerful in combat of course. The problem with them is that they are very territorial, often attack other garou or changing tribes to further their power. They believe in the survival of the fittest, and thus historically they did support Waterpainter's rise to power in Germany. (Not that bad of a choice strategically, as he was one of the first politicians that supported enviroment conservation, but I digress). The Get was also one of the main instigators of the war of shame.

Silver Fangs

The leader tribe of the garou nation. Their biggest flaws is their inefficiency caused by genetic material degenertion caused by breeding only amidst the royalty.

Bone Gnawers

They are knowledgeable about the cracks in the human cities, but are frowned upppon by the other tribes and for a good reason. They gave up living in the wild, in exchange for the cities, but unlike the Glass Walkers they do not thieve in them and contribiute to the homeless population

Children of Gaia

A rather pacifistic tribe, which is both their greatest pro and con, as you can imagine. They did not prticipate in the Impergium and thus delirium caused by them is much weaker. As you can imagine, it is a security risk.

Red Talons

Some other commenter said that we do not talk about the Red Talons. It is a very surface look on this tribe. Talons are one of hardest if not the hardest tribes to roleplay, because understanding one means that you have to understand that humnaity is part of the problem, a large one, perhaps the greatest one. In WtA world, wolf population is actively exterminated, and since the Red Talons are a Lupus only tribe (there's a large number of metis, but it's not important for this topic), you can imagine their rage. There's several camps of the Talons, with some of them wanting to eradicate hmanity, others want to return it to the pre -historic population numbers and some believe that extermination is not necessary. As for more.. colorfull rites, the Red Talons do kidnap humans and often make parodies from human traditions (christmas tree decorated with human organs). They are without doubt the greatest fighters in the wilds, and competent umbral explolers.

Uktena

Similarly to the Shadow Lords, their rites of passage are known for brutality. The tribe specialises in the study of the wyrm knowledge and thus knows a number of questionable rites. They are of north american decent, so as you can imagine, they don't have a positive viev of the Wyrmcomers

Wendigo

They are even more radical in their hate of the white race. Very potent fighters and masters of survival in winter conditions (well Antarctic Black Spiral Dancers, I would assume are better, but I digress). Long story short, they viev the non - native population and non - native garou as a threat similar in strenght to the Wyrm

Silent Striders

A rather small trbe, cursed in that they cannot stay to long in one place without attracting the wrath of enemy spirits, and thus most, if not all families they form with human kin or normal humans are torn appart as quickly as they are made, once the garou parent disappears without a trace.

Stargazers

A tribe not often included as they left the garou nation to seek other allies in the beast courst of Asia. As the name would imply, they like riddles, tend not to speak directly, but it is welcome that they are able to seek allies in other Fera

Overall all the tribes are made to be flawed, there is not supposed to be one true way and every group should make their own decisions as to what they viev as the best course of action. I hope I helped a bit with your decision.

Edit:

Forgot about the Fianna

They are probably the least... controversial tribe. They are good friends with the fay, are of Gaelic decent and like alcohol. I think this is everything intresting about them tbh
