Claims of Holding Back his Power
1. Claims the anger he felt at himself in the above scene manifested by his quitting the Avengers, returning to Asgard and not appearing on Earth for an entire year (and several publishing years in fact). However, this nature of his persists to this very day and became a recurring theme in his adventures. He is, in fact, just that powerful and to live on Earth, he must hold back. He certainly must restrain himself against foes of lesser stature, such as Puma.
2. Says he hesitates to unleash his full power until pushed to the brink.
3. Here, against Grog the Godslayer he supposedly uses a self-proclaimed full-force Mjolnir throw to no avail. But after getting over his own insecurities, he throws one again to devastating effect.
