#techno:

C!Technoblade just has major memory issues and his full name is "Technoblade never dies" so that's why he keeps on saying it.

This paired with the fact that he also seemingly never dies just makes everyone else think its just his catchphrase and he never corrects them because who would he be to show his weakness like that.

Also he just has comedic timing so the only times he feels his memory slipping is after a near death occasion that any NORMAL person most certainly would have died during.

Just to make this funnier the voices are also unaware of this fact and just think their host has this cool catchphrase.

But C!Philza Minecraft knows because... Philza

(Minecraft is so brave, he's the bravest man I've ever met)
