The only Biggles I've seen is an island event when it asked me if I wanted to let Biggles have a go at researching alone as he had something he wanted to try.

I said yes and it told me I remembered too late that I had no villager named Biggles (which I didn't, but I was not very far in the game and thought I'd forgotten a name), and that by the time my villagers got back he'd wrecked the research table and lost tech points.
