What if Sabre had a power that made him basically invincible?

How it would work is the power would make him heal so fast, it's as if what was trying to hurt him just bounced off. Stab him? Sword just bounces off. Poison? No effect. Fire? Sabre just walks right through the flames lol. Throw him off a cliff? This guy gets up like nothing happened. Lightning? He doesn't even notice most of the time. Lava? He can't be submerged, so he just walks on it. And of it's coming from above, it slides off him.

I'm sure you get the idea.

Here are some situations as examples:

—

(Tree falls on Sabre)

Orange Steve: SABRE HOLY CRAP-

Sabre: (lifting up the tree) I'm fine. Chill.

Orange Steve: ...Right. You can do that.

—

(The time when Nightmare was about to kill him)

Nightmare: Then you shall perish.

Sabre: What-

(Lightning strikes Sabre, but after it's done he's completely fine.)

Nightmare: Wait WHAT-

Sabre: 'Kay then.

(Nightmare proceeds to get drop kicked)

—

(Light and Elemental looking for Sabre after he got yeeted by a giant Darkness)

Elemental: You sure it was this way?

Light: Sabre? You around here-

Sabre: (distant screaming from above)

(Sabre proceeds to fall from a nearby cliff, landing face-first.)

Elemental: HOLY-

Light: Oh hey, there you are.

Sabre: (Getting up and waving to Light) Yo.

Elemental: WH- HOW ARE YOU NOT DEAD?

Sabre: I can heal so fast, I'm basically invincible.

Light: We just stopped questioning it.

Elemental: (visible confusion)

—

(Reverse fighting Sabre and Rainbow, when a boulder falls from the mountain they're fighting near and hits Sabre.)

Reverse: HA! NOW HE'S DEAD!

Rainbow: Haha no he's not.

Sabre: (climbing out from under the boulder) No I'm not.

Reverse: ARE YOU EVEN MORTAL?!

—

(Corrected Sun member charging towards Sabre)

Sabre: Whoop-

(Gets stabbed with the member's spear, it bounces off, then Sabre just looks at him for a minute.)

CSM: (visible panic and confusion)

Sabre: Clearly you haven't met me before.

(CSM is quickly captured. Light comes over because he heard something.)

Light: What's going- oh.

Sabre: Pfft, he tried to stab me.

Light: Clearly he hasn't met you before.

Sabre: That's what I said.
