Sangue Navajo (Navajo Blood) is a crowning storyline of awesome. It starts when two Corrupt Hicks on a train shoot four Navajo kids For the Evulz, and both the governor of Arizona and colonel Elbert, commander of Fort Defiance, try and pass the murder for self defense to protect the two rich men. Tex replies to that with an awesome, if bloodless (almost: an idiot tried to shoot Tex and was promptly killed for that), Roaring Rampage of Revenge:
when Elbert has the gall to tell Tex it was self defence, our hero insults him to his face and, threatened with arrest, takes him hostage to leave the fort before freeing him;
after that he goes to the nearby town of Gallup to see the faces of the murderers Sam Hope and Bart Barlow, and beats up Barlow in public when he says a few words he should have not said;
Elbert, who is not an idiot (and had actually tried to stop the shooting, as he was on the same train), has called for reinforcements and, received a squadron from Fort Wingate, attacks first. As soon as he leaves, Tex and the Navajos capture the remaining garrison of Fort Defiance and burn it to the ground, and then capture Elbert's attack force;
in the meantime, anticipating the need to feed the soldiers, Tex goes and steals Hope's cattle, burns his ranch to the ground just to add insult to injury, and, stumbling on Hope, gives him a beating too;
when asked to surrender, Elbert fired on Kit Willer, who was under a white flag. Tex gave him another beating, had him stripped to his underwear and shaven bald, and then freed him;
when another squadron from Fort Wingate came to see what had happened, Tex captured them too;
still, the US Army remains too powerful, and when they'll bring their forces to bear the Navajos, in spite of their valour and their easily defended territory, will lose. That's why Tex got an embedded reporter (a journalist who was on the train when Hope and Barlow started shooting and denounced them on his newspaper) and, after capturing the second military expedition, had him send a reportage to the great newspaper of the East Coast. The result: the Washington Post, the New York Times, the Denver Post, the Baltimora Express, the Kansas Courier, the Santa Fe Examiner and the Phoenix Post started an hell of press campaign that caused the Department of War to categorically order to cease any and all operations that could provoke the Navajos and the Congress to order the start of an enquiry about the facts, with the governor being forced to order the arrest of the two hicks. That's victory, completely bloodless... But not enough;
Tex, to make a favour to the Navajo tribe from which the victims hailed, convinces Gallup's sheriff to deputize him and assemble the most epic Posse in the history of the western genre: it's made of all the warriors of that Navajo tribe. And not to kill them, but to arrest them so they would get tried and hanged. It's almost too bad that Hope and Barlow, trying to escape, ended up killing each other...
In short, Tex started and won an Indian War, without killing a single soldier, in order to have justice.
Padma versus Mefisto. For most of the story arc Padma had not stopped Mefisto, trying instead to turn him to good. When at the end he's forced to actually fight him, and holding back as he was not allowed to kill, he conjured such nightmarish illusions that Mefisto was reduced to an harmless idiot from the sheer fear. Remember, Mefisto's the same guy who can casually deal with hellish powers...
In "The Hour of the Massacre", Tex and an anonimous salesman rout a large band of Apache Jicarillas. How? Easy: the salesman worked from Mauser and was trying to sell a scoped Gewehr 1888 rifle, with three times the range of the lever-action Winchesters used by the Apache. Between that and losing their chief at the first shot, it didn't take much to make them run.
