Advancing creatures for Gate is way better than having to go to other books for wacky monsters with enough HD.
When I played an Alienist with 3.0 Gate, the advanced pseudonatural solar was one of my favorites. I had several different creatures stated up, in various states of 'advanced' and 'leveled'. They weren't intended as specific entities as much as "The baddest pseudonatural purple worm gate can find me", to save the DM from having to stat up 34/36/38/40HD of horror every time I cast it. It's Gate. It's freakishly powerful. The bad guys get to use it too.
My favorites off the random gate list were:
- advanced pseudonatural solar
- advanced awakened pseudonatural iron golem barbarian/psychic warrior (think Evangelion)
- pseudonatural stirge swarm (all feeding aparati of a single Far Realms creature)
- advanced pseudonatural grizzly mastodon (The Trompplodon)
- advanced pseudonatural purple worm (The Finger. A collosal finger poking through the gate, dragging it around behind them. It's swallow whole attack was replaced with "squish and drag through the gate" and it's stinger was replaced with "swing the gate at someone")
- advanced paragon pseudonatural black pudding barbarian (Just eeew.)
