Superboy vs Thunderstrike

Oki, once again I try. The battle of the copies, no BFR:

1) Freestyle.

2) Thunderstrike with Bloodaxe.

3) Thunderstrike with Bloodaxe, Superboy has Kripto to help him.

Who wins?

Thunderstrike with the Axe beats Superboy and Krypto

Thunderstrike without the Bloodaxe looses to Superboy.

What's the bloodaxe?

It appears in the arch where Thunderstrike fights the Avengers, but I can't fully explain it myself.
