My first semi-lucid dream when I was younger involved me realising a monster in a nightmare wasn't real and turning into a power ranger to defeat him I didn't have much control or anything but just enough to change the dream's course of events a tiny bit.

I don't think i've really resembled any hero too closely in my lucids more recently. I'll say Goku is closest because I did fly in one of my dreams in a similar way to DBZ.
