The Defenders vs. The Avengers

Ill check it out if i can, i think i remember reading something in those lines. Anyway none wer equal to theyr top showings at the time. They had better against others.

True, it was Strange's like....4th appearance and loki's like 10th, neither were fully thought out. But, since loki is an immortal, it's doubtful his power has grown in a few years.
He's not a god like Thor or Odin, he's a dwarf frost giant.

I thought he was god of mischief or something...

He isn't a god like Thor and Odin.
He isn't even related to them, he's a stepchild born of a frost giant.

He's a dwarf frost giant.

There is a reason why Loki needed to steal Strange's magic to do things beyond his normal power, it's because Strange's magic and artifacts are beyond his own.

Yeah even in the myths Loki was never an Asgardian. Thats why he ends up against them with his sons by his side in ragnarok.
