As many people are interested, here is a list of all the char quotes I could find!

Vikings, Icelandic: Berserker jump heavy: Þú ert dauður! – You are dead! Warlord shield stance: HORÐU Á MIG! – Look at me! Berserker deflect: Náði þér! – Caught you! Raider unblockable: ÉG RÍF ÞIG Í BITA! - I'll tear you to pieces! Valkyrie: ÉG DREP ÞIG – I'll kill you!

Knights, Latin: Warden shoulder bash: Miserum! – Pitiful! Warden: Inseca Vos! – You insect! OR Ti secabo! – I'll cut you into pieces! Warden: Nulla misericordia! – No mercy! Peacekeeper stab: Peri! – Die!/Perish! Peacekeeper: Morituro! – You're gonna die! Lawbringer unblockable: Ad mortem, inimicus! - to death, my enemy! Lawbringer: No superstes! – No survivors!

The Samurai speak japanese, of course, but I sadly don't speak it and couldn't find any information on the quotes they say. Maybe someone can help to complete this list!
