I lived in Singapore for a while as a kid and we went to the beach one day where a monitor lizard showed up. Not a komodo dragon but still.
I don't really remember details - it's one of those family stories. I just remember we saw a monster. I think it was about 1.5 - 2m long, which is big enough but as a 4 - 5 year old kid it was a real life monster. It's one of those family stories and I think there's a box in storage somewhere with a picture of a monitor lizard 20 or 30 metres away.
My parents said they were told they can bite so we cut that beach trip short.
