Golden Ferocity

His [Fireheart's] confidence evaporated when he approached the RiverClan deputy [Leopardfur]. Although they were equals now in the hierarchy of their Clans, this she-cat had a fierce and commanding presence. Ever since ThunderClan and riverClan cats had fought at the gorge and a RiverClan warrior, Whiteclaw, had fallen to his death, Fireheart had felt her unforgiving hostility as sharp as thorns.

He [Fireheart] hurried after Bluestar and caught up in time to hear the ThunderClan leader thank Crookedstar formerly for RiverClan's generosity. Leopardfur stood beside them, gazing coolly at the ThunderClan cats.

"ThunderClan is in your debt," Bluestar meowed, dipping her head.

Fireheart saw Leopardfur narrow her eyes at Bluestar's words, her emerald eyes glittering. His paws pricked warily. What payment would RiverClan demand for this kindness? he wondered. He knew Leopardfur well enough to suspect that she would ask for something in return.

The news of Crookedstar's death didn't surprise him [Fireheart], but it still brought a pang of anxiety. Leopardstar would be a strong leader. good for RiverClan, but she had no love of ThunderClan.

".... I cannot speak for WindClan's needs, but RiverClan needs better hunting grounds even more than ThunderClan." [said Leopardstar}

A few RiverClan cats yowled their agreement, and Fireheart's fur bristled with apprehension.... The new RiverClan leader meant to expand her territory, and the logical direction was asross the river into ThunderClan land.

"Good day, Bluestar," Leopardstar meowed, her voice confident. "I've been waiting since moonset to see thunderClan cats, but I never hoped that one would be you." There was an edge of mockery in her tone, and Fireheart winced that the head of his Clan could be scorned so openly by other leaders.

"Sunningrocks has always belonged to RiverClan," Leopardstar retorted, "even though we allowed ThunderClan to hunt here for awhile. But ThunderClan stands in our debt after the help we gave you at the time of the fire. Today we claim that debt, Bluestar. We are taking Sunningrocks back."

- A Dangerous Path, pg. 184

.... Spitting, she [Leopardstar] flung herself at him [Fireheart], driving the breath out of his body as she hurled him to the ground.

Fireheart gripped the RiverClan leader's neck with his front paws and felt her powerful hind paws raking at his belly. Pain stabbed through him, and he slashed out blindly, feeling his claws score through fur. For a few heatbeats all he could see was Leopardstar's spotted pelt; his face was pressed into it, half smothering him, and he struggled to breathe.... Suddenly he wasn't sure that this was a battle he could win.

- A Dangerous Path, pg. 191

" I had him," Leopardstar panted, almost incoherant with fury. "I heard you just now. You warned him."

- A Dangerous Path, pg. 192

" Punish you?" Leopardstar's face was contorted in fury. " I'll claw your eyes out; I'll set you lose in the forest for the foxes to track down. Traitor! I'll- "

"You're all mad," he [Darkstripe] spat. "Joining a kittypet? Well, I'm not going to follow him, whatever any cat says."

"You'll obey orders," snapped Leopardstar.

"Make me," Darkstripe retorted. "You're not my leader."

For a few heartbeats Leopardstar looked at him with cold eyes. Then she shrugged. "Thank StarClan I'm not. You're about as much use as a dead fox. Very well, Darkstripe, do as you like."

- The Darkest Hour,  pg. 276

Leopardstar stepped forward. "I swear by StarClan that we will meet you at dawn tomorrow at Fourtrees. We will fight with you and WindClan against BloodClan."

- The Darkest Hour, pg. 277

Leopardstar appeared briefly, yowling hoarse encouragement to her warriors, before she vanished again in a surge of BloodClan cats.
