*Zelgius* Ike. I have long looked forward to the day we would fight again. Now that it is here, let us not delay any longer. Raise your sword and begin! *Ike* Let's finish this! *Tibarn* Stop right there. I've got a debt to settle with this scum. *Zelgius* True, your revenge against me remains incomplete. However, may I ask you to step aside for now? Though at different times, Ike and I both learned the way of the sword from the same master: one of Daein's famous Four Riders, General Gawain. He left Daein under an assumed name and formed a mercenary company. I was entranced by Greil's swordsmanship while he was in Daein. I studied under him, I fought next to him... I idolized him. When he left, I was crushed. I vowed to find him again, and challenge him to a duel. I had to know if I had surpassed him! Three years ago, I caught up to Greil. I challenged him to a duel, and was victorious. But, something was wrong... The fight had been too simple. I thought I'd never feel satisfaction again. Then, Ike told me why it had been so easy. Greil had severed all the tendons in his right hand, and swore never again to draw a blade. Can you imagine my joy at the news? I knew that a swordsman of his stature couldn't have been so easy to defeat! My master's skills were passed down to his son, Ike. I will defeat him and finally surpass my master! I trust that you understand. Once our fight is finished, I will allow you to settle your quarrel, Hawk King. *Ike* Please, Tibarn. *Tibarn* ...Fine. If you're taking my place, you'd better win. Got that? *Ike* Of course. This is my chance to avenge my father's death. This time, he won't walk away. *Zelgius* Let us begin. *Mist* Ike! Be careful! *Ike* Trust me, all right? *Mist* ...Fine. *Zelgius* I won't allow anyone to interfere with our fight. *Ike* Agreed. It's better this way. I can focus on you! *Zelgius* No draw. No escape. One wins. One loses. We shall end this. One of us will live... And one of us will die. *Ike* I'm ready. Good-bye, General Zelgius.
This is already badass with just Ike and Zelgius, but give some credit to Tibarn as well. Man is reasonably and justifiably pissed at Zelgius and wants his head, but he has the calmness to hear both out and decide to let Ike carry out that revenge for him too, knowing that for what he went through, its far more personal for Ike than it is for him.
he killed him cus greil was his master who trained him in the ways of the sword, and he was angry when greil left daein and he also wanted to defeat him so he could prove he was better than him..im pretty sure thats why
He wanted to prove to himself he was better than the man who taught him swordplay, but was disappointed in the fight. Only after Ike told him greil cut the tendons in his arm did he understand why the fight went the way it did. He let ike become as powerful as he did so he could face off against the one who learned everything Greil knew, to fully test himself. Read his wiki if you want the full story he's a great character
